Picture of Old lens, New Camera
The idea.
Basically, I want to put an old lens on a new camera. M54 would need an adapter. but as I have not or could not buy what fabriqué ..... but...HOW??

I show you how!!

Step 1: Dismounted

Picture of Dismounted
The lens is going to change (ZENITH HELIOS 58mm).
Remove the back of the 58mm. on the picture you can see a 300mm lens that dismounted the back so you can place IN the 58mm.

Lol, I've got the same lens and an adapter for it. actually awesome lens :D but yeah. better get an adapter. it's like 1$

Bravo! Some people don't seem to understand that starving artists can quite literally be starving artists and cannot afford to spend money on adapters, as cheap as they may seem to be. Also there's something to be said for someone who can do it themselves rather than rely on other resources. Good work!

Or just get one of those adapters :

Mm i know.. But...no have time, patience, money, etc.
I living in brazil.
The best option.

This is insanely clever. Well done. Bravo.

For me though, thank goodness I can just buy adapters for my m43 Lumix. Speaking of which, I think I hear the the vintage primes calling my name over on ebay.

Why agonize if the transition can buy a ring?
m42 to nokon,canon,.... :)
Yes it seems like a lot of work just to get a lense to fit. I searched all over for an adaptor for Canon lenses. Found some, cost the earth but while on holiday to the USA this year I found one at a sensible price. Now I can fit all my old lenses (manual operation of course) but as the results are THERE, adjustments can be made on the spot. I can now use my extension bellows, big telephoto and anything else that has survived the ravages of time and fungus.

Very clever! I didn't imagine that we can adapt an old lens on a digital camera (or do I misunderstand?).
Yes, the media (film, sensor) only cares about the optics and the optics is just glass. But .. Sensors in digital cameras come in different sizes. If the sensor is same size as the film area in film camera then the pictures taken with both cameras are similar. A digital camera with that big sensor is marked as "full frame" (http://en.wikipedia.org/wiki/Full-frame_digital_SLR). But if the sensor is smaller than film frame (36x24mm) then the optics on the digital camera give an image that (compared to the film camera images with same optics) seems like more zoomed in or "tele".
@ Pablomar33: excellent improvisation and detailed instructable. One comment. I didn’t really know what was the real purpose of reconditioning the lens other than to use attach it to a different camera. Your statement “”the new distance measurement from the outer lens to the second database adapter 300mm. really gave 44mm! that's good! “” appears to imply, to me, that you needed to achieve that distance to something, not quite that clear to me. However, what kind of saved the day for me was Libahunt’s comments and the link. Thanks for that.

So, @ Libahunt, and everyone else: I have thousands of slides and 35mm negatives. I got this old idea of using my daughter’s Nikon D7000 DSLR camera with its Nikkor 18 to 200 lens to digitize the mentioned material. The camera specs say “23.6 x 15.6 mm CMOS sensor; total pixels: 16.9 million” which is what you were referring to, less than “full frame” ….
So I imagined to come up with a couple of cardboard tube extensions to FIND the right distance to place that Nikkor lens away from the camera body to COVER the full 35mm slide area.

Any idea or suggestions of approximated distance to start with? The main problem for me is that the camera is with her and I am kind of afraid to have to “experiment” too much with that piece of expensive equipment which is not mine. I will appreciate any inputs from anyone. Thanks.

if you can!
so if you can not use the motor for autofocus camera and can not control the aperture.
what is interesting is the effect achieved. one more retro, vintage style.

thanks for the comment!

Interesting and involved instructable. You are clever to adapt the old lens to your digital camera. I gather you modified it to respond to the camera's automatic controls. I have old FD lenses and bought a manufactured adapter. You lose all automatic control and must focus manually. Then I interpolate the exposure settings and set them manually also. With digital you can see the results immediately and make adjustments.

The original mount was M42, not M54, and adapters for them are EXTREMELY common. You just destroyed two lenses when you could have bout a 10 dollar adapter.

Thanks for that comment. I cringed a little when I saw that poor Zenit lens being dismantled. Since you have a Canon DSLR, you can use any lens system that has a flange to lens distance bigger than 44mm. You can be sure there will be an adapter for most of the lens systems on ebay. As said before, this is an m42/Screw mount lens, thus a cheap ~$3-4 adapter works perfectly.

See http://en.wikipedia.org/wiki/Flange_focal_distance for a list of lens systems you can find adapter for Canon DSLR. Everything under Canon EF should fit easily on your DSLR.

The only reason I'd "destroy" a lens would be for flange distance smaller than 44mm. I did the same kind of modification on a Minolta mount 90mm Macro lens since it was the only solution to use it on my Canon DSLR. Instead of getting a broken EF lens, you can use a cheap m42 adapter as a mount for the conversion.

first: live in brazil, and here arrives all too late for example if I buy the adapter on e-bay.

second: you're right about the adapter. really confused me. I will try to fix it.

third: 300mm which extracted the ring was broken and fungi.
if the 300mm was not broken and moldy ... NEVER disarm for that purpose haha

thanks for the comment!

You create a lift.. how do you know exact distance to lift? Isn't that critical?
