Compatibility of Nikon-S / old Contax lenses mounted on M-mount bodies using an Amede

I will update after my external mount arrived.

That's interesting to read. I couldn't get either 50/1.1 version to mount on my Amedeo adapter or Zen-shooter's original Orion adapter.

Since Amedeo is now machining his adapters from scratch, it should be completely possible to make them so they focus in the same direction as Leica lenses (only internal mount lenses could be used of course).

Confirm Zunow 50/1.1 Contax mount works

It'd be nice if the R3m had a Nikon Mount option for that 50mm f/1.1

Think about using small Zeiss Sonnar501, 5 Amedeo Leica Nikon adapter. Do you have any of the lens, use this combination, you can post it? In addition, the use of the combination, you may have found any drawbacks?

[furcafe]

Which "Zeiss Sonnar" are you asking about? The modern CZ for Nikon S-mount that was sold only in Japan or the classic Carl Zeiss Jena, Zeiss-Opton, & Carl Zeiss Sonnars in Contax RF mount?

Amedeo has both Nikon & Contax RF adapters for Leica screw & M-mounts. All of the above Sonnars will work just fine using the appropriate adapter (I have both types & they work perfectly on the M9). The only drawbacks are if you are really used to the Leica focus direction & have to switch between the adapted lens & a standard Leica lens. Nikon copied their RF lens mount design from Zeiss Ikon, so both Contax & Nikon RF lenses focus in the opposite direction from Leica glass.

I just wanted to report that I tried my 50mm f2.5 Skopar with the Amedeo M adapter on my Bessa-T and the rear of the lens fouls the RF cam on the camera so no go for the Voigtlanders I guess (but I don't have a Leica body to try it on so can't confirm for the M series).

I recently bought a kipon Contax to LTM adapter, the main idea was to mount the 50 millenium nikkor on M/ or LTM mount

it was decent priced, very well built, with black front, I was positively surprised with the build quality.

the millenium lens mounts perfectly, but the heliocoid doesn't move ( at all), so i'm a littlebit bummed, as the the adapter is pointless for me at this time, anybody else tried those kipons?

do I understand right, that it might only support external lens designs?

does the helicoid of the amadeos move? or is the some kind of trick i didn't think of?

thanks for any advice
regards

That's weird. The helicoid should rotate otherwise what's the point? Except for the scale focus type adapter designed specifically for external mount lenses with large rear elements (38/1.8 etc.) Amedeo adapters have helicoids that rotate just like the helicoid on a Nikon-S body.

With a non-moving helicoid why have a helicoid at all?
Can you show a picture of the adapter?

[digitalintrigue]

It must be only for external mount lenses? Or the helicoid is stuck?

[digitalintrigue]

If this is the one, the helical should move

[maitani]

exactly what i was thinking, non movin helicoid = useless... an explanation would be for external lenses only, but even then, it should be states somewhere, shouldn't it?

thanks for the feedback guys, yes it's exactly this adapter digitalintrigues post, from this seller, i have the black one, but helicoid does not move.. i've been thinking to mill it for myself, as i have access to cnc machines nearby, it seems blocked inside, i will try to upload a picture later, from the innards. so you can see

[maitani]

here are 2 shots front and back,

as you see on the back the 2 'nicks' seem to avoid the helicoid from moving

[maitani]

i feel ashamed, the dang thing was only locked in close focus position (but very very tight sitting though..) i dared to put some force, now it's moving perfectly... i'm glad i didn't start the CNC machine yet...

thanks for all your help guys, this forum just rocks... I need to loosen it out with my millenium now.

yes the kipon was a great deal and it came with 3 types of ltm to m adapters, so really great price, i know kindai for maybe the best adapters, i had one for my OM/Canon combo in the past, i guess the kipon is made in china copy, but i'm not sure about it. but i can assure you it's of great build quality.

thanks again guys, really happy

[jarski]

hope your Kipon adapter focuses right. I had their LTM/M adapters once, which let focus rotate "beyond infinity", and decided never again these Chinese adapters.

I will test it and give some feedback in this topic, if there's an issue, i'll be getting one from amadeo for sure.

i just spent a pretty penny on a amedeo adapter,
to try it on my helios-103 and the jupiter-8m with aperture clicks.

can't wait to try this on my r-d1.

I just got an Amedeo adapter for Nikon - Leica M and I haven't found an answer about using a Jupiter-12 (Contax mount) on the adapter to Leica M body. The J-12 is incredibly inexpensive and many of the samples in Contax mount are essentially brand new.
Are there any physical restrictions that prevent the lens from being used and focused accurately? If so, I could also use a file or dremel to relieve any binding or clearance issues. Filing down part of a $30 lens is no big deal to me to get it working in the adapter.
So, anyone use the J-12 in the standard adapter? Is it possible?
Thanks all.

Phil, I don't have any experience with the J-12 but the rear element looks to be on the large side so would probably foul on the cam follower wheel on the camera side, preventing focusing.

The same thing happens with the W-Nikkor 3.5cm f/1.8. The lens will fit in the adapter, but the adapter/lens combo can't be mounted on the camera.

But, considering a J-12 is only $30 I'd give it a try anyway. It might work.

[Phil_F_NM]

Yup, that's what I'm doing. Scored a J-12 in excellent condition for $40 including shipping (from a US seller, to boot!)
I'm thinking if there is any binding from that deep metal collar against the RF cam follower in the M body, I'll just take off some of the metal with a file or Dremel tool to leave room for the cam follower. I'm confident I'll wind up with a usable lens.
I'll definitely post my results here after I butcher the back of the lens!

That shouldn't be necessary. The LTM version of the lens has the same large rear element and fits Leicas with no problem.

FYI the deep metal collar on the rear of the lens slots into the adapter so doesn't go anywhere near the RF cam follower.

[Phil_F_NM]

My J-12 arrived today and throwing caution to the wind I immediately stuck it on the adapter and onto my M9.
Nothing happened to the shutter. Whew.
So, the spring-loaded brass collar that turns the Amedeo helical (or Contax/Nikon camera) does in fact interfere with focusing closer than about 10 meters. Simple fix, I took off the collar, filed down the edge enough to clear the edge of the focusing cam surface and not foul the cam follower in the camera. After that, I found that focus was ever so slightly off. I then filed down the aluminum shim which gives the lens its proper registration and found the sweet spot, after a good amount of trial and error (I only had one of these shims and I don't like making them.) Focus is spot on now up close and infinity is good to go as well.

As far as this lens is concerned, I don't know why I never owned one before. I think it's amazing. It's probably more 35mm lens than I need and it can make better photos than I can take, I think.

I walked through Manhattan today snapping away and trying to get used to the lens. The long focus throw I'm not a big fan of but the lack of distortion and great resolution for only $40 easily make up for that.

I have it coded as a V1 28mm Elmarit and the vignetting is gone. None to speak of. I usually shoot a lot of black and white anyway so that isn't as much of a bother.

Here's a shot looking at Jay Maisel's studio/bank vault on Bowery St.



All in all, I'm extremely happy with the J-12.
