Serial # is 180142, so it is within the first series on Rolands page

I will post pics of the lens the upcoming days, and yes I plan to treat it carefully

Good night and thanks

Looks like a blast to use!  Bjørn, #10 is excellent.  Would love to see it as a well size print!

Not to my knowledge. At least for DX or FX cameras. My 10 OP has worked with them all. I prefer to use a relay system for the DX models though so the image is circular and not cut top and bottom.

Bjørn, have you found any way to safely mount the Nikkor-O 21/4 on Nikon DSLRs?  Would it be possible to use an extension tube followed by a relay lens? I know we're cautioned against mounting this lens on bodies after the F2.  As I understand it this is because these bodies lack a tab that keeps this breech-lock lens from rotating during mounting.  If the lens rotate this damages the locked-up mirror due to the tight tolerances involved.

I just now tried fooling around with a few lenses of the same extended-rear non-retrofocus configuration. 

Unfortunately, my Canon FL 19/3.5 will not fit either of my FD to μ4/3 lens adapters due to a protruding screw inside the mount.  It also won't mount on my "BH" FD to F non-optical converter.

I tried to mount my Nikkor 21/4 on my Fotodiox and Voigtlander F to μ4/3 lens adapters and those wouldn't work either.  My Voigtlander 15mm/4.5 (F-mount, design inspired by the 21/4) adapts just fine via a Fotodiox adapter and works on a μ4/3 camera, though I'm not sure what the point of this particular combination would be given the huge crop involved.

I'll have to try putting these F-mount lenses on my A6000 as soon as I can find the adapter I misplaced.  I didn't try mounting them on my Speed Boosters. ;D

The Nikkor-O 21mm f/4 is definitely best left on a shelf, of course you could use a relay but the resulting image would suffer even more than the bare lens, there are so many other 20mm lenses to play with ;)

Oh dear.

NEVER EVER THINK OF MOUNTING THE 21/4 NIKKOR-O

on any camera except Nikon F, F2, or late Nikkormats

It will mount on a mirrorless model through the appropriate adapter, however, performance is quite poor.

Ditto. #10 is a very cool and interesting composition indeed.

Thank you, Erik and Bjørn, for your responses.  I have been very careful to never attempt to mount this lens on any SLR (film or digital) other than an F2.  I suspect the poor performance on mirrorless cameras is due at least in part to ray angle issues, given the small size of the rear element and its proximity to the sensor.

I may need to get out a roll of film here.

The 21/4 did very well on film. Tackled strong light sources in exceptional manner too.

Looking forward to 10 OP photos taken with your DSLRs :D

The 10 OP looks almost mint. Good on you.

Here is 10 OP on the Nikon Df. The lens is surprisingly sharp.

The advantage with this approach is of course you can, and ought to, use LiveView for framing. My 10 OP is (surprise, surprise ...) equipped with a CPU, thus exposures are spot on.
