What a fantatic job! This is one of the rare vintage zooms with a good optical quality but especially with a non-extending or non-rotating front end. I was planning to do something similar like you did on the Canon nFD 35-105 f3.5, wich is not as bright as the tokina but is completely parafocal! The problem isn't the zoom because is internal but the rotating and extending front wich is used for focus, would you suggest the design you applied on your latest Helios 44 proget?
I'm not sure because I don't have a Canon nFD 35-105 lens. However, I made a prototype of a similar zoom lens Tokina (vivitar, hoya, etc.) 35-105 f3.5 housing upgrade, so I'll tell you my personal thoughts based on this. First, the method applied to the Helios 44-2 is effective for small lenses, but it is difficult to secure a place to fix it so that the front part of the housing can be firmly supported. In particular, it seems difficult to apply to zoom lenses with multiple rotating rings. You will have to decide by comparing the disadvantage of rotating the front of the lens, the problem that the structure of the housing becomes unstable or complicated, and the convenience of operation. I hope this is the answer to your question.
Does that mean that the re-housing part interferes with the smooth operation of the zoom ring? In my experience, Tokina lenses are very sturdy, but the smooth operation of the zoom ring is often hindered by loosening of internal screws, etc. This must be resolved through a separate repair. As it is only an upgrade method that wraps around the outside of the existing lens housing, it cannot solve the problem of defects in the original lens operation.
This is really good work! Just wow! I read a few comments asking about fitting it on the version with the screw on hood. I have that version to. I was wondering if you can send the original file for the front part so i can make a few adjustments so i (and more people) can fit it on that version. The rest of the parts fit perfect. It's just a small change on the front end to make it work. Much appreciated!
@@MountainBreezeStudio awesome! Great work man, seriously. Please consider adding some Nikon ai lenses to your designs. I would love to fit my 28 and 35mm with your designs, and will contribute 100% financially.
nice work man! will you consider to change the font on those rings to DIN? And another suggestion is make the focal/focus/iris indicator line on the horizontal plane of this lens. I think it'll look more professional and more easy to use IMHO. if you're interested in more upgrade thoughts please let me know and I'll sent an email for more~
It's hard to expect to make it even for sale because I'm lazy! It would be better to download the free shared file using the link in the video description, print it out, and assemble it yourself. :)
I don't have any secret know-how or methods worth mentioning in detail. There is nothing special other than measuring the external value of the actual lens with a vernier caliper, and thinking about the lens structure, operation, and external design for an upgrade. After that, the process is the same as revealed in the video. :)
Hello, The Viltrox adapter is the focal reducer adapter, right? I don't have a Viltrox adapter so I haven't tested the actual mount, but I think it's probably not suitable for mounting. The above lens supporter is custom-designed for the Metabones 'EF-E' version(MB-EF-E-BT5), so it doesn't quite fit either the Metabones EF-E Speed booster or EF-MTF speed booster version. The reason is that the speed booster or focal reducer adapters have to be manufactured in a form that is less expanded than a general expansion adapter without an optical element due to the influence of the internal optical element, so there is a difference in thickness in the appearance of the actual product. Also, adapters with similar Alka Swiss type feet for fixing may not fit because the design is slightly different for each product. Since the lens supporter only serves to fix the front part a little more stably, it seems better to exclude the supporter part if it is used in combination with other types of adapters.
Looks cool, but why did you tested the lens for focus breathing and parfocality? Your rehousing is just a cosmetical add-on, not a redesign of lenses’ mechanics nor optics - nothing would have changed with or without your rehousing.
Rumor has it that it has the same optical design as the Angenue 28-70, so I tested it. Of course, attaching something to the outside of the lens does not change the optical performance. :)
It's custom designed for Tokina AT-X pro 28-70mm, so I think it probably won't fit the Angenieux 28-70! Due to the short turning radius of the manual focus ring, it seems that it will be possible to improve fine-tuning by using additional follow focus, etc., such as the Nucleaus Nano.
I used a grub screw with a round tip. The pointed shape has the advantage of being easily fixed, but inevitably it easily leaves unpleasant scratches on the surface of the lens housing.
Yes, Nikon, Pentax lens focus rotation direction is opposite of Canon, ZEISS, etc. Probably because it is a lens for Nikon mount, it seems to be the same way as Nikon lens. In general, cinema lenses are like ZEISS or Canon.
Since the clutch push-pull operation is perpendicular to the axis of rotation of the focus ring, there was no difficulty in maintaining manual focus. Disabling the focus ring clutch mechanism isn't too difficult, but it doesn't seem necessary.
Wow dude you are FANTASTIC for this. Any chance you can PLEASE upload only FOCUS GEAR RING files for Helios -44 2/58mm, f2 Helios 40-2 85mm, f1.5 Super multi coated Takumar 28mm f3.5 Super multi coated Takumar 35mm f2 So i can send it for print. Will 100% pay you for it if you charge for it.

Even though I didn't any knowledge about this, but I can feel his effort. Thanks buddy.

will this rehousing improve the zoom? my copy's zoom is not smooth at all

Really cool!
Can you do a rehousing for Vivitar 135mm f2.8 ? That would be amazing :)
Great work dude! Very cool!
Awesome! Great work man, Can you do a rehousing for Contax Zeiss lenses? Man, that will be really cool. Thanks a lot for your work.
Unfortunately I don't have a Contax ZEISS lens so I can't try it.
This is really good work! Just wow! I read a few comments asking about fitting it on the version with the screw on hood. I have that version to.

Can I use this on non-pro version? Tokina 28-70mm F2.8?
If not. hope you'll make one someday for this lens... ❤❤❤
Yessss my next lens man you read my mind! Does it work without the lens suppot? Thanks
Yes. It works without problems.

Hi! What are the benefits of rehousing the lens please?
Any chance you might have a Tokina 11-16 ATX Pro in the future?
When I get that lens, I'm going to try it. But, I don't know when it will be. :)
nice work man!
will you consider to change the font on those rings to DIN?

Please rehousing for Cooke Speed Panchro 25, 50 and 75mm optics!
It would be unbelievable
This is the second version of the lens right? With the lens hood not be a screw mount but a click mount. ..?
Yes, it's probably called the second version. The original hood mounting method of the lens is not a screw mount, but a dedicated (bayonet) mount.
Great work! I like it!
Very cool work, I would like to buy some, is it possible?
It's hard to expect to make it even for sale because I'm lazy!
It would be better to download the free shared file using the link in the video description, print it out, and assemble it yourself. :)
Would you make a video on how to design a rehousing for a lens?
I don't have any secret know-how or methods worth mentioning in detail. There is nothing special other than measuring the external value of the actual lens with a vernier caliper, and thinking about the lens structure, operation, and external design for an upgrade.

Ah I see
Hello, thank you for your video and sharing your work with the whole world!
Do you know if the lens support fit the Viltrox adapter ?

@@MountainBreezeStudio Thank you for the detailed reply, I'll go without the supporter. Keep up the wonderful channel!

What if you have the A-mount version? Will this work too?
You know how to declick the lens? Can't find a video anywhere
Hi, do you think this will work with the regular 2.8 version that has the screw on hood?
Sorry. I'm not sure because I don't have that lens.
Is there a way I can buy a kit from you ?
Can I get the file to print
will this work with the real Angenieux 28-70? did you found an improvement on pulling focus with a follow focus?
It's custom designed for Tokina AT-X pro 28-70mm, so I think it probably won't fit the Angenieux 28-70! Due to the short turning radius of the manual focus ring, it seems that it will be possible to improve fine-tuning by using additional follow focus, etc., such as the Nucleaus Nano.
Does your grub screws have a pointed or flat end?
I used a grub screw with a round tip. The pointed shape has the advantage of being easily fixed, but inevitably it easily leaves unpleasant scratches on the surface of the lens housing.
is the focus reverse compared to Canon?
Yes, Nikon, Pentax lens focus rotation direction is opposite of Canon, ZEISS, etc. Probably because it is a lens for Nikon mount, it seems to be the same way as Nikon lens. In general, cinema lenses are like ZEISS or Canon.
I’d buy these mods in a heartbeat… instead of PayPal why not just put them on eBay?
Hi thank you. I made one
The last File in post doesnt download
Can u fit this?
I re-uploaded that file. Please try the download again. :)
@@MountainBreezeStudio nice!
What about version that prevent focus ring clutch mechanism to work? So lens stay manual focus all the time?
Since the clutch push-pull operation is perpendicular to the axis of rotation of the focus ring, there was no difficulty in maintaining manual focus. Disabling the focus ring clutch mechanism isn't too difficult, but it doesn't seem necessary.
I thought this was a rehousing of the lens not just some add on😂I mean looks nice but I wish the whole lens design was changed!
Wow dude you are FANTASTIC for this. Any chance you can PLEASE upload only FOCUS GEAR RING files for
Helios -44 2/58mm, f2
Helios 40-2 85mm, f1.5
Super multi coated Takumar 28mm f3.5
Super multi coated Takumar 35mm f2
So i can send it for print. Will 100% pay you for it if you charge for it.
Sorry. I am not running channels for commercial purposes and I do not respond to individual production requests.
@@MountainBreezeStudio Totally feel you dude...Anyway good work 👍🏿
What kind of Nikon F to EF adapter did you use? Thank you
I used the EF-E Metabones adapter and the Nikon F to ef adapter.
@@MountainBreezeStudio thank you :)
Does it fit with the newer fix F2.8 version?
Sorry. I don't know because I haven't tested it.
