Title: Rear Lens Clearance of Leica Elmarit-R 28mm f/2.8 on FF camera D800E?
Post by: Gerald Botkin on July 19, 2013, 11:51:14 am: Elmarit-R 28mm ROM version production run in 2002 with s/n's 3944114 - 3944313 of which there were only 200 hundred made according to leica wiki index. 1st image

I have read photographers using the 2nd image version, ROM and non-ROM before the year 2002 with no problems in the 11 333 series lenses. Their 28mm's look like the rear lens/ shroud of the 2nd image. I want to use the 1st image on a FF D800E camera if it clears my mirror, of course converting the mount with a Leitax mount. Dave with Leitax couldn't give me a answer if it would work. Maybe someone out there has one with a s/n from 2002 that looks like the 1st image, can compare it with the 2nd image and tell me if there is a difference in the height @ infinity focus on the rear lens/shroud. I don't know if the specs in the leica wiki index are for all later versions even with the different rear lens/ shrouds as seen in these photos. Thank you for your help.

It's worth it in the end and the combination of a D800E and Leica R's is unbeatable!

I don't see any basis for this assumption. The lenses are a completely different designs.

As a rule of thumb, lenses that fit the Leicaflex SL are likely to clear the mirrors full-frame CaNikon cameras. The 28mm Elmarit-R is OK on the Leicaflex SL, the 28-90 zoom isn't.

The mirror swings in an arc so the diameter of the rear protrusion matters too.

If the zoom works OK on Marc's D800E I see no reason the 28 wouldn't because it has more clearance than the zoom.
