- Опубликовано: 27 июл 2021
- How do you know if you have a more regular Pentax 7-element Super-Takumar 50mm f/1.4 or the fabled 'Planar Killer' 8-element Super Tak 50 1.4?
In this video, we display the physical differences between these two awesome lenses!
0:58 - needs to be a 'Super-Takumar', not an S-M-C or SMC.
1:15 - needs to have the infrared mark on the right side of the 4
1:39 - A/M instead of Auto/Man aperture switch
1:55 - will not have numbers on the bottom of the switch
2:09 - will not have '⋅' but instead will have an f/2
2:34 - rear lens element protrudes
3:03 - 'less' thoriated
3:32 - will only have 6 aperture blades; no aperture lever
4:20 - • Pentax K-3 Mark III: U...

I dig this video. Nicely concise. Thanks, PentaxTips.
Thank god I watched your video before going on eBay. Many people label the 7 element version as 8 and thanks to you, I can tell them apart.
Glad you found it useful!
I have the seven element Radioactive Takumar 50mm1.4 my favorite 50mm lens
Very interesting! Good info!
Thanks for watching!
Thanks for this gem of a video
Nice video. A few years ago it took me a long time to tell the difference. You have some tips in here I didn't know. Thanks
They’re really fun lenses. Glad you liked it
The only way to determine whether your lens is an 8-element one, is to look at the protruding rear element. In final production 7-element glass was put into 8-element casings, so the position of the red IR line is not decisive! The remark that Asahi lost money on this lens have never been confirmed, neither that it was supposed to be the Planar killer. These remarks stem from journalists who wanted to make a scoop. The problem of which cameras can this lens be used on is not in the mirror hitting the rear element, it is the aperture push plate hitting the rear element because of its physical shape. Later SV/H3v and S1a/H1a cameras have a different push plate with a spacial cut-out to accommodate to this lens. Don't go for the orange color of the R on the rewind crank as opposed to the green R, because cranks can be swapped in under 10 seconds.
Mine has all the signs of 7 element version but strangely markings next to Automatic manual aperture switch have "M and A"
I have a similar problem. My housing has signs of both the 7 and 8 element version. A and M, is not labeled smc, and the ir marker is to the left of the 4? Seems like an 8 element in a mixed housing.
I've known for a while that I have an 8 element variant, mine has the R under the infrared mark, but I never knew that some of the 8 element versions could be radioactive. Neat! I'll have to check it with a Giger counter. I will say that it lives up to its reputation, there's something dreamlike about the images that come from this lens.
the R is the 1st Gen before the non-R which is the 2nd Gen of the 8 element variant.
I'm not sure if I have the 7 element.. I mean the red line is on the left of the 4.. however my lens also has "a" and "m" instead of the "auto" and "man"
The lens is so popular that there are ‘makeshift’ models out there. The best way to tell is to the protruding rear element. That’s the best way to know for sure.
@@PentaxTips okay thanks for the help
I have a 7 element 50mm tak. Just curious with regards to the aperture between 1.4 and 2.8 is the dot f2 or is the unmarked click f2? If its the former then what f stop number is the click? Likewise if its the latter what is the f stop for the dot? Thanks 👍
I've got one of these lenses, but I don't know which one. 6 aperture blades, a and m instead of auto and man, but the rear element does not protrude as much as I've seen the 8 element version, and it has the ir marker to the left of the 4. It also does not say smc, just super takumar. Did these lenses have crossover production between elements and housings? Like older element design in a new 7 element housing? Very confusing.
The best way to tell apart the two is the protruding rear element. If it does not protrude then I am willing to bet that it is a 7-element lens in a 8-element body (the bodies can interchange parts).
I have model of this lens, s/n 5748830, R sign is on the left side of 4, labels are A and M on the automatic/manual aperture switch, there is no any number on that A/M switch (on the other side), it don`t have dot "." between 1.2 and 2 on A ring, and rear element protrude substantially over the rear ring. It has everything, as you said and if I understand well, except R sign (which is from the left of 4) of 8 element lens. Can someone help me to understand is this 7 or 8 element lens? I am totally confused.
If the lens protrudes, that’s an 8-element. That extra glass is the only way to definitively tell. All other parts *could* have been swapped out
I remember hearing or reading somewhere (Simon's Utak on youtube I think) that 7-element versions may or may not be radioactive. I haven't heard anywhere else that an 8-element may contain radioactive glass. Can anyone confirm this? Not trying to be pedantic, I just hold an 8-element up to my head pretty often and haven't been worrying about radiation.
From a historical standpoint I think differences are interesting. From a shooter's perspective (of many years) I've never, ever, EVER seen even side-by-side comparisons that place the 8-element much better if at all to the 7-element version. Confirmation bias can be a powerful thing. The price difference between them is for collectors and suckers. If one just wants to shoot this legend of a renderer, just pick up a nice, clean 7-element version and enjoy.
(Btw the only sure way to know you have a true 8-element version, one that hasn't been tampered with to look like one, is by looking at.... the rear element. As he notes here, it protrudes much further beyond the mount.)
