Wonderful! There are only a few members who own this very rare lens. It is good to see one that is being used. Please share more!
 
Great images shown here! Thanks.
I have such a lens. I sometimes use it with the F2, with mirror-lockup.

Raid, the F-mount version of this lens is not rare (but just as good). This is the S-mount version, only a few hundred lenses were made. It is one of the rarest lenses for the S-mount, and highly coveted by collectors.

Yes, you are correct. My version is not rare. I was just being practical. I have done the same with a Canon 19/3.5 which is not the rare RF version. The glass is the same.

It is very practical of you! My solution was to get the more modern Voigtlander 21mm SC Skopar, but I do miss that classic biogon goodness.
 
My god, that's gorgeous. I always find 21mm a tad too wide for me personally, but those photos are stunning.
 
Great shots - I'm always impressed at the performance of these older biogon super wides, personally a little vignetting seems a very small price to pay for such low distortion and compact size.
 
The main downside with such non-retro focus lenses is that they cannot be used with Leica M digital cameras. I am not sure if these lenses work well with other brand digital cameras or not. I also have a Rokkor 21/4 with an adapter Rokkor-Leica. The rear glass elements get too close to the sensor.

No downside.
S mount 21/4 can be mounted on Z6 body using a combination of SHOTEN Z to Leica M andRayqual SC-NZ.O adapter. See the image with 21/4 in different generation bodies (S mount 21/4 on S3, F mount 21/4 on F and S mount 21/4 with adapters on Z6)
You need to remount to shoot 7ft to inf or 3ft to 5ft. For 5-7ft, it seems to interfere with adapter rim hence need to step forward or back to reach above 7ft or below 5ft. I also know people using S mount 21/4 with Leica M10 (in monochorme only since the protruded lens does not effectuate color sensor properly but works fine in monochrome). I have tried F mount 21/4 but the protruded rear element is longer than S mount hence cannot mount to Z6.
Please try at your own risk.

Not perfect but ostensibly works for all practical purposes... See the sample shots using Z6 + 21/4 (S mount)

Holy cow UV76! Not one, but two! Are they both yours? I thought there was a limit of one per person...hehe...

Thanks for sharing these photos. Richard Haw recently tested the F-mount 2.1cm lens on his website, including lots of digital samples. I a little surprised at how poorly the lens performed on digital. It is clear to me that there are many better choices for a 21mm lens on digital cameras, but this lens is best suited for its original purpose.

Thanks for the link to Richard Haw's report on the F mount 21/4 Nikkor. I am not surprised at all at the difference in performance for a digital camera versus a film camera. I have seen such differences with the Zeiss Hologon 16/8. The lens does well in B&W with a digital M.There is no distortion when used with film (on an M3 in my case).

Thanks for your reply here. It is still too complex for my taste. Yes, it is OK with a Monochrom since the colors get smeared up with a digital sensor on a Leica M10 (or M8 or M9) camera.

raid I guess there are many digital format optimized lenses for Leica (Summilux, Skopar etc.) out there, I use my 21/4 almost exclusively on film.

Old wide angle lenses were not designed or built to be used with digital cameras. Some lenses give OK looking B&W images on digital cameras.

That's pretty cool you own AND use the S-mount Nikkor-O 2.1cm. The images from it look nice. I was lucky to obtain a nice clean copy of the Biogon 21mm f4.5 this year from a RRF member, and it has been a lot of fun on my S2.

About ten years back I was lucky enough to find a Nikkor-O 2.1cm S mount lens in mint condition complete with the finder and the original case. It came included in a box of Nikon rangefinder cameras, lenses and accessories. The price for the whole box of stuff was $500.00. I was shocked to find this lens and learn just how rare it is. I decided I could be happy with the Zeiss 21 4.5 Biogon and sold the Nikkor-O to a collector in Japan.
