Which adapter is being used here?

Lomo T43 40mm f/4 on canon EF mount

I'm trying to figure out which mount he used. If anyone speaks Russian it would be of great help.

It's a M42 to EOS adapter. The way the modification done is not scientific.

 

There is a high risk that the lens rear element will hit the camera mirror assembly. It's not worth it.

Is there a better means of mounting this lens? Maybe with some kind of converter? I'm really determined to have it on this camera body, would there still be a few millimeters of clearance from the mirror if I just use the adapter?

I don't think we have enough information to even consider trying to answer your question. On what camera body are you determined to have it? "This camera body" is rather unspecific.

This guy converts it to Sony in 20 seconds.

The film is sped up, but he refers to the adapter as M43.

People adapt vinatge manual focus lenses to use on DSLRs will have different problems. Putting the adapted lens on a full frame or cropped sensor camera body is not the same. 

 

You may find some information in this link : https://www.panoramaplanet.de/comp/#Pentax

 

A lot of lenses will clash with the mirror of 5D/5D2/5D3(examples of FF camera) and some will not. If use on cropped sensor bodies, most of them are okay.

 

Before modification you have to have some knowledge of back focal length、registration distance、flange distance、flange focal distance etc. Even if a lens can be adapted to mount onto a camera, it may not be able to focus to close distance or infinity.

 

Adapter rings of different manufacturers have different thickness and tolerence. You need to try a few of them to see their adaptability. Modifying the M42 to EOS adapter as shown in the video is not an easy task and even if you have the skill and machine to get it done, you may not be able to align the lens properly to the adapter.

 

It may seem easy but it is not at all. You may check out the following link to find useful information in some older posts.

I have modified over 30 vintage lenses but they are not all good. A very basic nifty fifty and EF-s 24 2.8 pancake will certainly be better than most of these adapted lenses

 

Good luck and have fun. But do not break your camera. ( I scratched some mount rings and jammed some focus pins before. You will get frustrated if you cannot manage to open up the camera to fix these very possible damages)

Sony mirrorless is not M43. (micro four third)

 

Mathieu Stern used just the front lens adapted to a M42 to M42 helicoid.

 

Then add a M42 to sony NEX (or whatever mirrorless camera mount type) for camera mounting.

 

Mirrorless cameras have very short registration distance and thus can adapt a lot of manul focus lenses with specific adapters.

With suitable helicoids, focusing from close to far is possible in most cases.

 

I doubt they will work on DSLRs.
