Really enjoy your logical approach to explaining vintage lenses. However, I would like to know how you sand down the adaptor to fit, if you wouldn’t mind please.

[@VintageOptiks]

The step-up ring is very easy to sand down. I use some medium grit sandpaper, I place the step-up ring on it and then with circular motions I proceed to sand it down. No machines necessary. This one had to be sanded down about 1mm to reach infinity. I'll advise to try the step-up ring first by taping it with some electrical tape to the lens before gluing it. This way you can check if you can definitely reach infinity and if not it needs more sanding. I had to check a few times before I had reached it. Glad you are enjoying the videos. Let me know if you need any other help.

[@ijlo-b]

Great video!! Since watching this I've joiined the flickr group showing this and purchased a Yashica Half 17 EE Rapid. Hopefully I can adapt this Yashinon lens. Rather than helicoid I'm hoping it works well on my Fotodiox Pronto adapter which is in the post too ;-)

Thank you for the nice review 😊 Some models of the USSR M42 lenses like: helios 55mm f2 and Zenitar 50mm f1.7 have only 2 aperture blades, making square bokeh, and it is also swirls... While 2 bleded Helios are extremely rare and there are many fakes, or modifications of the original ones, Zenitar's 2 bleded design was original for all lenses straight out of factory, plus Zenitar is multi-coated and delivers better contrast and colours, less swirly bokeh though...

So it is or Cooke Triplet, or Tessar... It is crazy to realise, how simplest and oldest designs can deliver one of the best performance... In contrast with huge elements counts for the modern lenses... I wish some of the modern brands will realize it and will make some classic line of the lenses, for their modern system, with AF an all those funky coatings and glass... So far it didn't go further than Carl Zeiss Sonnar 50mm f1.5 for Leica...

[@CvitanGrguricin]

Looks like a fun lens. Two question about detaching the lens: It seems like you didn't have to remove the leather and the lens board. Couldn't you just unscrew that retaining ring from the back? Also, couldn't you use that same thread that the retaining ring was screwed onto? Again, seems like unnecessary use of glue, just screw an adapter directly onto the thread and a helicoid after that.

[@VintageOptiks]

Unfortunately you can't access the retaining ring from the back, so the front was the only way. And there is not enough tread on the back to be able to screw an adapter. For me, gluing the step-up ring was the only option.

Hello, I'm purchasing vintage lenses for my Fujifilm XT-20, I found a medium format lens option (Bayonet 60 Pentacon 6), there is some restriction on using a lens that was designed for medium format in an aps-c as is the XT -20? does it impact images / functioning? Congratulations on the great content on the channel! Thank you so much

[@VintageOptiks]

Hi, no worries about using medium format lenses on APSC. They work just fine. You won't be able to use the full image circle of the lens but that's not an issue. People use them often with a tilt-shift adapter, because of the extra large image circle. Enjoy your lens and thank you for for your nice comment.

[@xxDecidensHonorisxx]

This is amazing. The question I have on adapting this lens to a mirrorless camera, even though I have an APS-C instead of a full frame mirrorless camera, it's still recommended to sand down the step up filter before mounting it to the focus helicoid correct?

[@VintageOptiks]

Yes, even with an APSC sensor camera you'll have to sand down the step-up ring. (about 1mm for Sony) Best thing to do is to tape the step-up ring to the lens (with some electrical tape) before you start to sand it down and check if you can reach infinity. If you can't, sand down the step-up ring a bit and check again (by taping it to the lens again). I had to do this 3 times before I was able to reach infinity on my camera. Once you are certain that you have infinity focus, you can super glue the step-up ring in place. Good luck!

Any tips for adapting to an older blackmagic cinema camera? I have one with an EF mount and one with an ARRI PL. I sanded the step up down a bit more than you did but can only get it to focus at a super close macro level... Thanks!

[@VintageOptiks]

Hi, the problem with both of the mounts you are trying to adapt this lens to is that they both have quite long flange focal distances. EF is 44mm and PL is 52mm. In comparison, Sony E mount (the one I use in the video) is only 18mm. That's why you can only focus in extreme macro situations. Unfortunately there is not much you can do as long as you are using these mounts.

@@VintageOptiks Yeah thats what I figured. An A7ii would work for landscapes and portrait shots though right?

[@VintageOptiks]

You can definitely use it on your cameras but you'll need to figure out how to adapt it (depending on the mount you need) and you'll need to see if you will be able to reach infinity (if that's important for you). I've only adapted it to Sony and don't know if this method will work on other camera systems. You can easily use it on your M42 camera, but as I mentioned, infinity focus will be what you need to figure out. If you just want to use it for close up shots, then you won't have any problems.

[@labandedancefing]

Really interesting vid ! Would you know what's the flange focal distance of this lens ? I'd love to try to adapt this lens but i dont have a Sony camera. Anyway, I just discovered your channel, I love your videos ! Keep up the good work

[@VintageOptiks]

Thank you! Unfortunately I haven't measured the Flange Focal Distance of this lens. And even if I did measure it it's not going to be super accurate, but more of an approximation. Whenever I adapt these fixed lenses getting infinity focus is a trial and error game. I have to sand the adapter a bit, then check how it works, then sand it again and so on. It's a fraction of a millimeter kind of game. The great thing about Sony E mount is that it has pretty short Focal Flange distance of only 18mm which is very helpful when adapting these old rangefinder lenses. What camera do you have?

Hi! I’m not sure if you’ll be able to find the necessary helicoid for your camera. The issue with a lot of these lenses is finding the right helicoid for your camera that will allow you to focus to infinity. Another thing that you also have to take into consideration is the flange focal distance, which is different with different camera systems. The reason why I adapt these lenses to Sony is because there are a lot of parts made for Sony E mount that work well with these DIY projects. I know that others have had a hard time finding helicoids that work for their camera systems such as Panasonic and Fuji. I hope you can find something that works for your camera. Good luck!

Well, I thought I was home free on a similar project. I found a honeywell camera with this lens (Mamiya Kominar 44mm) and the lens was easy to remove, following your instructions. Unfortunately, I'm adapting it to micro 4/3 and there seems to be only one m42 to m4/3 helicoid size and it is too thick, even without the m42 to 52mm step-up ring. The lens is too far from the sendor. I looked at my various other pentax/olympus/canon, etc. dedicated m4/3 adapters and they are all the same thickness. There are so many different length helicoids for m42 to m42, it's a shame that there only appears to be only one length for m42 to m4/3. All I can think to try is a m4/3 body cap, with a hole drilled through it, that I glue to one of the shorter m42 to m42 helicoids. I could then glue my m42 to 52mm step-up ring to the lens and screw that into the helicoid that is permanently glued to the m4/3 body cap.

[@VintageOptiks]

Yeah unfortunately these slim helicoid adapters that work with rangefinder lenses are not available for all camera systems. I hope you can find something that works with micro 4/3, so you can try the Mamiya Kominar lens.

[@Part_121]

@@VintageOptiks What I wound up doing was getting a M4/3 body cap, drilling a 35mm or 38mm (can't remember which, but it's the largest hole that could be drilled) hole in the body cap. then I epoxied an M42 to M42 coupler to the body cap. This allowed me to glue the M42 to M52 adapter to the lens, just as you recommended in the video. The two can then screw together and the lens can be removed, if desired, from the makeshift adapter if I get other rangefinder lenses. The one mistake I made was thinking that this much thinner assembly would allow me to get to infinity, but I didn't check it first (would have been tough with those think pieces) and the adapter is just a touch too fat. I'm going to order another body cap and coupler and try it again, now that I have a process. It's very fun trying all this out and I thank you for the ideas!

[@invisiblespark]

There are a lot of Smena cameras everywhere, do you think it that the lens can be adapted to a digital camera?

[@VintageOptiks]

Oh for sure! You can adapt any lens as long as you can remove it from the camera and find a way to attach an adapter. Also infinity focus can be a challenge sometimes. But I would love to try adapting the lens of the Smena one day! There are so many fun little lenses from old cameras that I would love to try adapting!

@@VintageOptiks Adapting vintage lenses is one of my hobbies aswell, but so far I have just used comercial adapters, nothing made by me (yet) . As a first step I ordered a 17-31mm M42 helicoid but I find that here in Romania there are a lot rangefinder type cameras in the 5-20$ price range. It may be a goldmine I haven't exploited, who knows..

[@VintageOptiks]

@@invisiblespark Making your own adapters is a lot of fun! And adapting these fixed lens rangefinders is addictive!! I love finding cheap ones and try to figure out how to use them on my digital camera. Sometimes you get some amazing gems!! That’s great that you can find a lot of cheap ones in your country. Sounds like a gold mine to me :)

How did you physically determine how much you had to sand off ring?

[@VintageOptiks]

First I tried the step-up ring by taping it to the lens and since I couldn’t reach infinity I started sanding it down and trying it again a few more times until it was just right. I had to take off about 1mm.

[@cinewillp6391]

@@VintageOptiks trial and error! thanks

[@visserindustries5293]

Do you happen to know the thread size of the inner retaining ring?

[@VintageOptiks]

Sorry I don’t.

[@axtran]

How did you determine that it was 1mm to shave off of the step-up adapter?

[@VintageOptiks]

It's simply a trial and error kind of process. First I start by taping the step-up ring with some electrical tape to the back of the lens. This way I can check if I can reach infinity before I glue it and if not, I need to sand it a bit. I had to sand and check a few times before I knew for sure I had reached infinity and then I was ready to superglue it in place. In this case, it was about 1mm to

[@axtran]

@@VintageOptiks so not bad if I sand too much?

[@VintageOptiks]

@@axtran No, because you can adjust with the helicoid.

[@srjungl3916]

How do you know how much you have to sand? I want to do this and adapt it to my nikon 7200

[@VintageOptiks]

It's a trial and error process. Since I don't know what the original Flange Focal Distance was of that lens there is no way to calculate perfectly how that same lens will translate to my digital camera's Flange Focal Distance. See this other video I made and you can understand the process better: kzbin.info/www/bejne/nXjEeIeigNurgKc

[@Warren3carpentry]

That is a sweet lens! Have to watch for one online!

[@VintageOptiks]

Really awesome lens indeed! And super cheap! I hope you’ll enjoy it.

[@krispaprocki9711]

Does anyone know if this would work on a Canon aps-c sensor?

[@VintageOptiks]

I don't think so because Canon cameras have a much shorter flange focal distance.

[@almontmaggot1]

How would I go about mounting this to an eos r?

[@VintageOptiks]

Sorry, but I’ve only adapted these fixed lenses to Sony cameras because there a lot of parts out there for DIY projects. The Canon systems is a whole other world and don’t have experience with it.

[@HumbleAmberyedke]

I've carenar 55mm f1.7 lens. Wanted to adapt it. Can you help?

[@VintageOptiks]

Doesn’t that lens have M42 mount?

[@HumbleAmberyedke]

@@VintageOptiks it has carena mount. Totally different kind.

[@HumbleAmberyedke]

I can show you pictures of it. I'm planning to modify it with canon macro reverse ring 😀

[@HumbleAmberyedke]

How to find exact distance for infinity focus?

[@VintageOptiks]

Ah ok. Very obscure mount.

Could you please tell what's the song playing from kzbin.info/www/bejne/qZa5q3pnmLypi7M

Hi, it’s not a song, it’s just a little audio clip.
