Though my face is falling off, I can't stop using this lens. I love it.
"I can't feel my face when I'm with you... "
A lens to die for!
I know Im asking randomly but does anyone know a tool to log back into an instagram account..?
I was dumb lost my password. I would love any tips you can give me!
@Samir Manuel instablaster :)
@Sutton Felix i really appreciate your reply. I got to the site thru google and Im in the hacking process atm.
Looks like it's gonna take quite some time so I will reply here later with my results.
@Sutton Felix it did the trick and I now got access to my account again. I'm so happy:D
Thank you so much, you saved my account!
@Samir Manuel happy to help =)
I love how RUclipsra started to make videos about 5months ago to 1 year ago about this lense yet you made this video 7 years ago incredible visionary
I love this lens. I have a mint condition copy of all 4 versions. Each has it’s own personality.
My old man gave me a honeywell pentax ES that he used in his teenage years. Been sitting around in my room coz Im really not into film photography, more of a digital photography guy. Last night I was cleaning all my camera gears and decided to pick it up and clean it and to my surprise this was the lens that's on it that I've not noticed before. Long story short my m42 to fuji x mount is on its way now :)
Can this lens be used on a Nikon d7200 with a m42 adaptor? or are there some issues with focus. Thank you in advance
I have a 50mm f1.4 on the way !! ... I have the 55mm f2 which is INCREDIBLE when I do my flower pics !!! ... super sharp and colors slightly warm but sweet ... thanks for the recommend !!!!
I have a 8 element lens with thorium I don’t understand can you clarify . Do the serial numbers just apply then in this case . ??
Though they are not using thoriated glass to my knowledge, what is your opinion of the Konika Hexanon (AR mount)....to start....the 40mm/1.8?
I had the early 50mm 1.4 m42 screw mount purchased back in the 60’s.with the Pentax Spotmatic camera(Asahi) I actually sold it and purchased another 50mm f1.4 SMC-M k mount which I still have.
I'm mid repair of my takumar 50 1.4... the aperture wouldn't stop down and I've narrowed down the problem but don't know how to fix it. The two pins attached to the arm of the aperture control doesn't want to spring back into place. Any advise on what to do next? I can email you pictures if that will help I just need an email to send it to. Thanks!
This video answers my questions about your position with this type of lenses. I am getting one and will be pretty damn careful with it but will love it as crazy just as my other Takumar lenses.
what if you use live view with the camera are you getting as much exposure?
This is absolutely fantastic!
Just got one on e-bay for 60.00 bucks, mint condition (supposedly) will clean it up and play with radiation a little bit
Thanks again for the great info man, I keep opening my eyes more and more as a prime lens shooter thanks to your channel
make sure to get the right adapter and be careful about its rear element hitting your mirror
Yep, got the M42 adapter and I use an X-T2 so no mirror muahaha!
@@kathodosdotcom Hello Ken, I just received my 50 1.4 Super Takumar 8 element, from Japan. 1393172 Serial Number, IR right of 4, A M marking, there is no POINT in the place of 2, has 6 blades and Back element is protruding at infinity, All characteristics are there for it to be the 8 element which you say is NOT RADIOACTIVE. But WHY it seems a bit yellow to me????? Also How should I go about not hitting the mirror.? Only way is Through view finder and NOT focus at infinity? Any other solution? I have both a Canon and a Nikon. Not a Fuji yet...Thank you again for being here !!!
AWESOME video!!!!!! Do the Takumar 135mm next! :)
I've just bought Pentax-M SMC 50mm f/1.2 F2 is it any where near as good as 1.4.
Yesterday I stumbled upon this lens which is EXTREMELY rare in my country, so I bought it for your recommendation and it cost me only $60, what's a bargain considered I didn't need to pay for any shipping, and now I'm happy as a worm in the pile of 💩
Mint condition by the way...
So I found out my room mate has one of these. Might order an adapter for my D800e... does it harm the camera at all?
Just snagged mint, excellent + condition SMC version on eBay for $90. Got outbid at the last second on an Auto Rikenon 55mm F1.4. Not a bad consolation prize!
Heyah! Would you consider buying one off eBay, for cheap, but with a small fungus on the rear glass element - and cleaning it?
Or is that living too dangerously?
which is better: Auto Takumar 55mm f2 or Takumar 50 f1.4?
I have the 50 mm f 1,4 8 element, the 50 mm f 1;4 7 element radioaktive and the SMC 50 mm 1;4 7 elements. They are gooooood, fantastic and wonderful made. After all the years the focusing are as new! I first SAS the lenses as a body when my father had these.
Thomas Edetun, I have a super takumar 7 element version. Is it worth trying the super-multi-coated or SMC version? Are they much better in terms of colors, contrast, sharpness and flare resistance?
There are som small difference, the Super Multi Coated and SMC are a little bit better. Concerning flare, contrast and so but i could be happy with either one of them. If you don’t mind spending the money go for it.
Thomas Edetun, thank you for your answer!:)
How does it compare to its analog of Pentax M?
what are the top ten lenses of all time Ken. it would be awesome if you can
Ken.. I received one of these a couple of days ago. The focus dial is nice and smooth when the lens is off my K&F M42-FX adapter... BUT when it is on the adapter the dial needs quite a lot more force to turn when going towards the infinity end .. I noticed this is when the rear element is extending past the screw thread.. Any ideas ? I don't have this issue with my Helios lenses on the M42 adapter.
I observed the same thing with mine (with M42-EF adapter.) In my case it was even more pronounced. Without the adapter it just got sticky when extending past the screw thread, but did not seem to be a big issue. On the adapter it was so tight that turning the focus ring often took the lens off the adapter!!!!! I took it apart, cleaned and greased it. There was also external sign of external denting, but not very pronounced. I think yours might be also dented a little bit, or just a little misaligned or needs greasing. Taking it apart to do any work on it - take EXTRA care of it because you are going to be exposed to dust and grease that has been exposed to a lot of radiation. While using the lens once in a while is of no serious health concern (you get exposed to a lot more radioactivity if you are a frequent flyer), inhaling radioactive dust is a major health hazard, not just to you but to pets and especially children in the house. Do not attempt if not trained to work with radioactivity.
The 50mm f1.4 (I have the SMC version.) seems to me to produce a cooler color palette than other Takumars.
I found a Pentax Super multi coated 50mm 1.4 but it does not say Takumar? I have never seen a lens like this for pentax. Is says made in Japan but no Takumar label? Anybody seen one and what are your thoughts? I found it for a really good price...Thanks!!
Thank you for sharing your knowledge sir! It’s my understanding that the camera itself blocks some if not all of the radiation???? I’m not a radiation expert, but I’ve heard others say it can be blocked by a piece of paper. Can you confirm or deny this? I personally don’t care, I just bought a SMC Super Tac f1.4 50 but haven’t received it yet. I now own 5 Super Tacumars and I love them. I love vintage lens videos! Keep em comimg!
Is there any way you can sum your microphone? The stereo thing is annoying when you talk into one side of the mic.
Every single one I saw on ebay was not declared as a redioactive. Either people don't know or don't want to mention it.
What are the other 9? :D
Do the screw mount ones have the same issue with hitting the mirror on DSLRs like the those triplet lenses?
if not using the right adapter YES, but not on a fuji or other mirrorless
How do you store it?
I’ve read that these radioactive lenses impact sensor noise and sensor coatings on digital cameras very shortly after using them. I’ve opted to only use them on a beater camera like a 60d or something rather than my 1DC.
The Contax 120mm macro for the Contax 645 2 1/4 camera was considered the best lens on the planet. Especially if you shot Chrome in macro. A 3-D quality unmatched. I imagine the Hassy lens with the same specs was right there too.
Can I use that with my d5500 and proper adapter? I wont try it with my 7500 just yet. Thanks a bunch. Some dinero will be in the mail shortly
Getting mixed msgs - does the back of a smc super tak interfere with nikon mirror when focused to infinity and if so is there a solution?
I do not know about Nikon, but it also happens with my Canon 5D classic. The solution is to get an adapter with a glass element. (There's a Nikon adapter for that, but no Canon adapter). Sadly, the glass will add its distortion, so overall, this lens cannot be used on a number of DSLRs for infinity focus because the back element hits the mirror. I'm limited on the 5D classic to about 4m/16ft or closer without worrying about damaging the mirror and potentially ruining the camera. However, it is perfectly adaptable to mirrorless where there's plenty of space for the protruding back element at infinity focus.
This also happens with many more M42 lenses - the Helios 44 for example... I was quite devastated, because I got these two lenses explicitly for the 5D classic, so I have a vintage camera with wonderful manual vintage lenses... which work only for close range, and there stopped down as the 5D has no tools to allow for accurate manual focusing for shallow depths. These issues are non-existent with the mirrorless cameras...
It it allowed to carry it on an airplane to the united states? I mean do the airport security have any issues?
Don't forget your SRPD and film badge... is that an anpdr 27? Interesting. I never considered that a lens could be RAM.
Ken I am thinking about getting one for my fuji ..... do they damage the sensor on a Fuji XT2 based on say occasional usage ! ... thanks in advance of your reply.
No, they do not. Just do not leave the lens on the camera for extended time periods (talking about months.) Shoot, remove lens. Store lens in a container, away from your bed. (Do not keep it on your night stand.) I've been using the 7 blade Asahi Super Takumar on my M50 and 5D classic for quite a while, and the camera bodies / sensors are fine.
Which lens would be better to use on the Black Magic Pocket Cinema Camera 4k, the SMC version or the Super Takumar 50mm f1.4? 7 or 8 elements? Would these lenses harm the camera?
did you get your answer?
These lenses will harm your camera sensor and from what I’ve read effect the sensor noise within hours of having it on the camera. There are coatings on the sensors too that react to the radiation. Best to use on a beater camera.
Hello Angry Photographer. I adapted the lens on my Nikon, but it does not focus all the way (actually it focuses about 20% of the lens focusing range). Do I need specific adapter, or maybe another camera? :)
Yeah Nikon is notoriously hard camera body to adapt to.
You can't for the most part.
I'm a Nikon shooter and experienced the same.
I bought a Fujifilm X-T30 II for my adapted lenses; the best decision ever!!! This lens with the Fujifilm color science, ABSOLUTELY STUNNING!!!
Is the SMC takumar 50mm f/1.4 lens radioactive? A silly question to ask but I'm not sure if this differs from the lens you spoke about in the video?
HELL YES, very radioactive
Thank you! Is there a better alternative that I can use for an M4/3 camera?
I just scored one of these for $65 (it's on it's way) This WILL fit on my Asahi Pentax K1000 right? or will I need an adapter mount?
you'll need a m42 to k mount adapter, I recommend the official Pentax one.
Does the radiation effect the digital sensor ?
"one slight drawback..."
LOL
but I love this lens I even buying this 2 PCs
have you experienced any problems focusing to infinity on these when using an adapter?
you may experience this since m42 adapters can be tricky to work with but if you use a good hyperfocal technique you should be fine
no, but i only use them now on Fuji
word, thank you
I was looking at that one too - has anyone tried?
Martin Murphy you can adjust your adapter to it
I did you have to loosen ring in your m42 adapter rotate it till you get it then screw it back to hold in that place where you found your spot by rotating it
hi ken, is the 8 elements without thorium any better than the 7 elements thorium?
its a lot more rare, but its nowhere near as good……..so its worse, but more expensive cause its rare :P
FAIL hehehe
sghound, I can confirm that the 8 element lens is less sharp in the center, even worse in the corners, it has way less microcontrast and the colors are somewhat pale. But it’s not radioactive. It’s rare and expensive. I’d say it’s not worth it.
I can answer the nikon reason for not really using it. We cant focus to infinity with m42 lenses.
Same is true for Canon EF mount - infinity focusing: the back element hits the mirror. If you are lucky, then the mirror will just get stuck, and you can release the mirror by changing the focus or unscrewing the lens. When unlucky, the coating from the mirror will start to peel off in pieces, or the mirror falls off, or breaks...
i just bought a 50 1.4 & 55 1.8 mm ex & ex+ , dont know the serials yet for $60/ plus shipping , oh boy i hope they get through customs short shoots with them for sure
That's a great deal
how dose this lens compare to the 55mm f2 version?
all the pentax sluts (including me) agree that the 50mm 1.4 is the cats ass, its that extra awesome, and it is
also its MUCH cheaper now than it was a mere 10 years ago……these lenses are mostly 50 years old
i recently was at an estate auction and bought a aluminum case full of 6 pentax camera bodies and 7 or 8 Takumar M42 lenses plus 2 50mm 1.4.SMC Super.lenses and now i love them. i was gonna sell them on eBay but after watching a few videos on these lenses i think ill buy a couple adapters and use them on my Nikon F cameras. but wait...i was just thinking why do i need to buy an adapter which i have done already when i have 6 cameras that came with the lenses.. several different M42 mount Pentax screw mount cameras....thanks for the information..just dont lick the radiated lens
Interesting video... most people seem to say that the version 1 (8 element, including one triplet group) of this lens is superior to the SMC version. Also, it isn't radioactive. Have you tried that one?
Thoriated glass. Kodak Aero Ektar reconnaissance lenses need a review on your channel.
You might be incorrect about the 8 element serial numbers. I have an 8 element lens with a serial number of 1,134,444. Infrared marker "ir" to the right of f4 and an obvious protruding rear element. Also, just an A & M for Auto & Manual switch. 😮
Which lens mount do you recommend to use with a Nikon D800?
that statement makes no sense.
Oh whoops.... I meant lens adapter. Sorry. I was thinking of a couple things when I wrote that.... lol... Anyway, which M42 to Nikon F mount do you recommend? There's too many to choose from.....
Watch your vids when i can. Preferable to TV. Why is the later SMC superior to the earlier Takumar 50mm f/1.4? Someone is selling a near mint SMC over here for $79 & after watching this, i am tempted to add this to my others.
Later models are multi coated
you're saying that the serial number needs to be under 800,000 to be an 8 element but from what I'm reading on forums mine is an 8 element even though the serial number is 1,376,168. It has the red line on the inside of the 4 on the aperture, the rear element bulges out so it can't be set flat on a table, and it just has an "A" and a "M" marking. Please help me!!! I don't want to be using a radioactive lens
He's wrong. See my comment.
hi Ken. can you tell if my D600 will meter on M or A mode with this lens? Thanks
A little late, but my D610 can meter with the 55mm f2 and the 85mm f1.9 on M mode (haven't tried A mode, because I always shoot M) so I'm 99% sure it will meter with the 50mm f1.4. I'm finding out tomorrow.
@@RubenvanKuik can this be used with an glassless adapter? I've been shying away from m42 glass on a nikon because of the inability to infinity focus.
@@ldyrtdyrt8872 The glassless adapters work fine, but you're gonna be stuck not being able to focus past about 3 metres. So they're only really good for macro stuff, half body portraits and headshots. I've since switched to full frame mirrorless (Sony A7II) so I could adapt anything. Haven't regretted it for a second. If you want to try vintage lenses, I recommend the old AI(S) and AI converted Nikkors. They're excellent. Don't use non-AI lenses as they can damage your mount. You might also find a few old third party lenses (mainly Helios) that have been modified for Nikon bodies.
@@RubenvanKuik thanks for this.
@@ldyrtdyrt8872 You're welcome. Happy shooting :)
Welp, that's it Ken. Your early Christmas gift to us this year is a collection of exquisite lenses and potentially cancer. :p
ahhahhaha
Unfortunately, I can’t mount it to my beloved Pentax H3v.
Couldn't agree more with the title...IMHO virtually all M42 Asahi Pentax Takumar's provide superb images...personal fav is the 55mm f2 (run close by the Helios 44M 55mm f2)...you can get rid of the yellow tint using most types of light (doesn't have to be UV)...careful though if using on a full frame Canon...may hit your shutter as flange length is too short approaching infinity...great video sir!
yes, i know about removing the yellowing, yes it does have to be UV :)
sorry...should have written daylight...took three days each under an LED to clean up three of my taks...some people have claimed to have had success using blacklights too...keep up the great work
It is an awesome lens.
So my super takumar 8 element serial number 1376168 is radio active?
Tyler, if it has 8 elements and no yellow tint, then it should not be radioactive.
can you treat them with UV light?
I can confirm that UV helps to get rid of the yellow/brown tint. Even my bright bike lamp helped. The yellowish tint reduced drastically, but it seems that it can’t be delt with completely. I think I have only 5-10% of the yellowish tint left in my 7 element super-takumar. The rear element color turned blue from yellow-brown. But the remaining 5-10% would not go away. Maybe I’ll try the sun next time.
So what's the difference between the radiation being inside the lens and if it broke? Does it somewhat block some of it or what? I obviously know nothing about radiation lol!
tempered glass shatters and also makes dust.
normal glass breaks, not this stuff,
Wow lol
very interesting AP
look at this crazy CRAP
petapixel.com/2016/10/12/leicas-new-limited-edition-camera-covered-ping-pong-paddle-rubber/
i think i have the 8 element variation my serial is 1487188. does this mean that this lens dont have radiation properties? 50/1.4
need to be under 800,000, i have one 13xxx,xxx, just like yours, lol. good luck with that.
@@jxmai7687 does your lens have the red mark to the right of the 4 in the aperture marking? 🤔 that will be the indication its an 8 element lens!
@@New777World yes, i mean good luck with the radiation.
Being radioactive is that why I don't see any kind of fungus growth on my lens?
I found a flawless copy of the SMC Takumar 50 f1.4 for my NEX 7 and it indeed has some very interesting artsy rendering of bocca in closer up shots, but it is not mind blowing sharp at f1.4 -f2 like say the Sony Zeiss 50 f1.8 is. Interestingly, I shot a fall leaf scene across a lake in my neighborhood and at f8 and above this lens is tack sharp BUT the color output came out rather washed out and de saturated - even my kit 18-55 beat it in the color department. However I played with contrast settings in the Sony software and got the fall trees to absolutely pop with color - even my MD Rokkor 24 f2.8 which is known for color pop could not match it. Strange that the SOOC distance shots were so washed out at f8 - f22, and even stranger that the file had more headroom to add more color pop back in than the other two lenses I shot with - Sony kit 18-55, and Minolta MD Rokkor 24 f2.8 (which already rendered rich fall colors and didn't really need post processing). Anyone else notice this with APS C sensor cameras? By the way, I store this lens in a lead lined box I made using 1 inch golfers lead tape applied inside a tin box that held green tea.
yes, its NOT mind blowing sharp at 1.4, but what it DOES have your Zeiss doesnt is (well the zeiss is excellent already at this too) stellar microcontrast :P
praise the radioactive thorium in it for this :P
Nikon users have 3 hurdles with m42 mount lenses. Possible mirror slap. Using an adaptor with an infinity focus glass element making the pictures look like you are shooting through vaseline plus tons of CA. Using an adaptor without the infinity glass element limits your range of focus.
Kinda frustrating at first till i read somewhere that there are none of the issues mentioned above when those lenses are used on a Pentax mount with adaptor. In fact, the m42 mount is also known as the Pentax mount.
Glad i kept my Pentax K3 when i switched to Nikon.
on some lenses yes, mirror slap
in what cases takumar 55 1.4 is batter than voigtlander 58 1.4 ?
that lens is radioactive
and which is better ?
which ONE to buy? Please suggest. thanks
1. Takumar 50mm 1.4
2. Pentacon 50mm 1.8
3. Takumar 55 mm 1.8
pentacon
Yes. Thanks. Pentacon it is
Everyone is nice and different in it's own way, it depends what you looking for. I have the 3.
55 1.8
were any pentax 67 lenses radioactive ? do you know ?
ohhh hell yes, i owned some back in the day
is the regular 90mm 2.8? (with out leaf shutter )
i cant remember back that far man!
ok no problem
i did some searching acording to camera pedia only the pentax 6x7 102 2.4 super takumar is radioactive
camerapedia.wikia.com/wiki/Radioactive_lenses
Mine is sitting in my mailbox at home. I have 1.5 hours of work left, damn!
Ken you are saying below 1800000 doesn't have radiation or the elements changed to 7?
apparently now that varies from lens to lens, some are reporting radioactive ones at 1,500,000
Theoria Apophasis
Would this lens cause any problems through airport security?
hehe, no .
This is a tried and tested design. This the same exact lens design in the FA 50mm 1.4 auto focus on the Pentax digital. Or the awesome MZs
yuuuup
wow, the samples look awesome... i wonder if customs officers would flag down the radiation.
They always do.
found one for 42usd, serial number 6630851, is it radioactive? I'm clicking buy right now if it is.
thats within the range, its supposed to be according to my serial list…. does it have a slight yellow cast?
Yes it does, also there's a dirty cheap 1.8, serial no. 4276111 but that one looks crystal clear, you think it's worth it?
eye now have x-ray vision....takumareyeball!
What's the story behind the use of radioactive matter in lenses? Do they knew it was radioactive at the time?
sure they knew, ive made videos on WHY its added over the past few days
Theoria Apophasis ok i'll check. Thanks
I have some of these lenses Pentax lenses with yellowing. Does that mean that they are radioactive or just old yellowing lenses? I have to dig them out and check which models they are. Can non-radioactive lenses turn yellow too?
I also love MF lenses and only use AF when something is moving too fast to nail focus or only have one hand to hold the camera while holding a flash. I'd like to hear about your favorite MF only lenses.
radioactive :) its the rear 3 elements that are 40% thorium by weight :)
Wrong on both counts. Only the third one (biconvex half of the achromatic doublet) in has any Thorium and is the only one that yellows. Not sure where you got the 40% either. Highest by weight are by far for consumer optics are the Aero Ektars which max out at around 30%. These lenses are likely less than 15%. Here's a picture of the Radioactive element decemented from the non-radioactive side:
s33.postimg.org/5er0o8ecv/K1_AA1662.jpg
Never heard of it till today
its one of the most beloved lenses of all time, kinda forgotten now but by those who KNOW :)
I tested an S-M-C version (7 element), and was really disappointed. A cheap Minolta 50mm F2 outperformed it in terms of sharpness from F2 to F11. Perhaps my sample was mediocre.
Mine isn't razor sharp, either. The Fuji 35mm 2 or even Yashica 50mm 1.8 are sharper.
You can't really get a sharp image at 1.4 with just 7 glass elements, even the sharpest fifties like the Fujinon 1.4/50 and the Zeiss Planar 1.4/50 are not as sharp as you would expect, lenses like the Helios 44-2 or the cheap Zeiss Planar 1.7/50 outperform them, but you know, they're famous for their beautiful rendering, not for their sharpness
Does it matter if it's the SMC version or not when it comes to IQ?
SMC has better contrast and flare resistance due to improved coatings, especially when shooting into strong light. Otherwise, the optics are identical.
Ken, is it true that the 8 elements version is non radioactive?
I have this version and it is said to be non radioactive. I can confirm that it has no yellow tint at all.
...Do you think these radioactive lenses will get me stopped by the TSA?
The TSA always want to go through my whole carry-on bag, when I bring this lens.
Hadn't really understood it gave off gamma radiation !
Is it better then our Zeiss 35?
no, its radically diff however
Yes, is probably better than a Zeiss that is now made in Japan anyway because the German camera industry is extinct at this point.
Gamma changed bruce banner into the hulk
Yeah..... surely the Hulk should be yellow, well at least until he's been out into the sun....
How do we know Ken is talking about Takumars? He has the Geiger counter on his table.
The yellow cast can be a pain if you're not shooting B&W, but it can be colour corrected in-camera on Pentax bodies by choosing the "muted" inbuilt colour filter, and it will then supply a WYSIWYG JPG if that's what you want.
10:28 - 10:32 LOLOLOLOL!!!
you can clear the lenses with UV light man :)
The yellow tint can also reduce sharpness.
Are the 1.8 also radioactive ??
yup
I have that lens and also the 85 1.9 that is incredible lens and the 55 1.8 that is wow. All S M C. My profile picture is made with a Pentax with film of course :) And yes they are all radioactive but who cares ,
no matter how dangerous these are they are much less dangerous than smoking or drinking
ahhhhh cant wait for mine its on its way snagged it for 55 bucks!
make sure to get the right adapter and be careful about its rear element hitting your mirro
Theoria Apophasis which adaptor for a nikon d700
yeah I know but which brand? made by who!? it's not about the type of Mount but the fact that it needs to be well made so I don't kill my dslr
This vs the nikkor pancake, what do u say ???
certainly this pentax, but its radioactive and finding the right nikon adapter is hard
im recommending this for mirrorless mounting
but wouldn't a simple M42 mount work for it ?? all the canon people seem to be grabbing it and going gaga over it !!
true, but its the flange distance, you CAN with teh wrong adapter run into the rear element smacking the mirror
I saw something like an additional mount after m42 but that's for Canon maybe I can find something similar for nikon too. Cause I saw just a handful of people on Flickr with this lens and nikon.
If the radiation from these lenses was significant it would fog camera film when mounted on the old Spotmatic or whatever. There's also a great assessement of the risk here: www.google.co.uk/amp/s/amp.reddit.com/r/askscience/comments/11bj4s/thorium_coated_camera_lens_what_kind_of_danger_is/
So they look pretty safe - just don't break one and inhale the dust. Prob. a significant risk for lens repair guys, especially if they polish the glass. Love your vid reports, great work, keep 'em coming. Best, Iain.
So wouldn't the radiation expose the film in a film camera? I guess with that lens you've got to hurry up and use up all the film fast?
Auto or super takumar?
super, or SMC super
