Voigtlander 50mm f/2.5 S Mount

LTM version is more expensive. But now I know the problem with the S version I must either seek out a Nikon S2 or send the lens to DAG.

Filing the rear wouldn't be the first time I did this. Once I had to do a lot of filing to convert a Minolta 58mm f/1.2 to Nikon F mount.

Thank you everyone for the feedback and info.

Yep, the S-mount Skopar won't work on a Amedeo adapter unless you trim the metal shroud on the rear of the lens.

Lower right looks like Skopar lens on a S>LTM adapter. Right? And is that lens not filed down now? Or is it? I'm just trying to see what needs to be done.

My adapter is on loan currently. I have the camera. And the lens will be here shortly. Then when I have all pieces I'll understand more.

Its one of Amedeo's early S>LTM adapters, and the lens is filed down, exactly like the other lenses. If you don't file down the lens, the rear metal shroud collides with the focus cam on a rangefinder-coupled LTM or M camera.

Did you do the filing or did you send them to someone?
 
just get the lens in their proper mounts and be done with it...

These are Shintaros lenses (and his photo). I think the adapter may have been mine originally, and I sold it to Gabor, who later sold it to Shintaro, but it is all so long ago that the details are rusty now. To answer your question, I think Shintaro used a lathe remove metal. But I agree with Rich tbh. Just get the lens in the right mount. Adapted lenses are always a compromise.

Will the S mount Skopar 50/2.5 focus properly on a Contax IIa?

The 50 Skopar is an "S" lens (meaning Nikon S-mount), unlike the 35mm and wider lenses in the range which are "SC" lenses (meaning they're designed as S-mount but you won't see the focus error when used on a Contax body), so strictly speaking, no, the Skopar 50 won't focus properly on a Contax body.

In practice you may experience a bit of front focus (around 50-100mm) at MFD and f2.5, and the front focus reduces as you stop the lens down / focus further away. If you stop the lens down to f4 to f5.6 at MFD you should be fine.

from my review at the blog :eek::eek::eek:

sometimes i wonder why they just didnt make this an internal mount like the heliar :rolleyes:

That pincushion tho :eek: I agree its a bit odd Cosina made it an external rather than an internal mount lens.
 
If there is pincushion distortion, it is really minimal. I will make some test shots soon.

I like the external mount, but I've changed the ugly red and yellow engravings into pink, just like the old Nikkor lenses.

I love the shade.

Erik.

I talked to DAG the other day and he'll machine down the rear metal shroud to fit the adapter/LTM camera. Even with the price he quoted the total is still under what the LTM version is selling for these days. The S lenses are cheap comparatively.

the pincushion looks ugly, right? :eek::eek::eek:

the old nikkor-H has a similar profile but this one looks more ugly. did you see the tiles on the wall picture at my blog?
 
The S-Skopar is the sharpest 50mm lens I have ever seen.

The distortion Jon mentioned is next to nothing.

took this one to see if the distortion will be obvious in real photos.

from my Bony a7 :eek::eek::eek:

too much contrast for me but its good for some cases.
 
Richard, I don't see much distortion in your shots. Have you ever tried a prewar Leitz Summitar?

In b+w contrast is not a problem as you can always print softer. The Summicron 50mm f/2 v4 is even contrastier than the S-Skopar.

the distortion is most obvious on the aluminium rail on my picture of the ramen restaurant and the storefront with the coke machine :eek::eek::eek:
the concrete beam on the temple photo has it, too.

i can even see it in your picture near the spherical tank. (1/3) and at the bottom,too.

its not too different from a nikkor-H and may even have less of it.

i only have an elmar. :rolleyes: i dont want to venture into leicas. nikkors are already quite expensive for me :rolleyes:
 
I've been using the Nikkor H since 1971. Indeed it has a tremendous lot of distortion near the borders of the picture.

You mention parts inside the picture, towards the centre. I will have a look at that; in the case of distortion I only look at the borders of the picture: there should the distortion be the worst, but probably not always.

Thank you for your reaction.

Btw, it is not a tank but an egg of a giant bird.


Erik.
