21mm zeiss ZM f/4.5

I would, except how would you code it? the 21 would have some real cyan shift if used with an IR filter. Hand coding with a sharpie is a hit or miss affair. More miss than hit for me. Anyone able to get around this issue with Zeiss lenses?

Yes, Tony Rose has them. Do you have to buy a new flange for JM to code it? He says you have to send him the flange removed from the lens...

New flange - coded, the M8 is convinced the Biogon 21 is an Elmarit 21 asph. Works like a dream.
 
I just recieved my 21f4.5 Biogon. Stuck it on a M2 (because that was the one that had film in it!) and will proced to shoot with it for the next couple of days and let you know what it is like. I have the old 21/4.5 in Contax mount so it will be interesting to see how they perform side by side.
The hood is the same as for the 21/2,8 ZM so it will block the finder in the R4M a bit, but I suspect that there is another hood for it. The 25 mm ZM hood works too, though I dont know if it will vignet (yet).
I am "unthawing" some rolls of Fuji ACROS for "testing" this lens against the old Biogon and the 21f4 VC and assorted 21/2,8' as well as the 21/3.4 Super Angulon.
They have promised nice sunny weather for the next little while, so this will give me an excuse to wander about with various lenses.
It is slightly bigger than the 21/4VC in M-mount, but smaller than the 21/2.8 (same diameter of the barrell but considerably shorter).

Brilliant, Tom! Looking forward to your findings and thoughts.
 
I did post some trial shots with the ZM 21f4.5 on my flickr site (see below) and I also shot the same subjects with my old Biogon 21/4,5 on a S3. Flickr resolution is not enough to judge resolution, but it gives you an idea of things like gray scale and fall off (and flare- the ZM has none whilst the older Biogon is a bit sensitive to it).
 
My souces say he had it outfitted with eyes/goggles so the VF could be used instead of an external VF.

I very much like the idea of goggles for the wides, should be a regular option with all of them.

I heard the 4.5 came with the 50 mount so you have to email zeiss and order a 28 mm mount get it send it to Milch get it back send it to either zeiss to kkep the warranty or to Don Goldberg to switch the mount. I did this with the 21 2.8 zeiss nice lens David
 
The 21/4.5 does indeed bring up the 50 frames. I must admit that it would have been nice to have it bring up the 28, but as it is mainly going to be used on the R4M it really does not matter.
Ah. the hacking of the 21/3,4! Years ago I devised a way of sticking the goggles from the old Summicron 35 onto my 21 S-A and changed the mounting claw to give me 28 frames. The magnification of the 28 frame on a M6/M4P closely approximated a 21. A friend did the conversion as i did not have the confidence of putting one of my favourite lenses in a lathe and turn down the mount. My last one of these is now in Japan and all in all I think a dozen of these conversions were made, including one of my 21/2.8 Asph. It kind of worked, but the R4M is a better solution!
