[Leica] Leica R to Fuji X adapter

[cummer at netvigator.com (H&ECummer)]

Hi David,
I have no experience with R lenses on the Fuji X series cameras (yet). My R 
lenses have all been leitaxed to Nikon bayonets and I use them on my Nikon 
D800E. I tried them first on a Canon 5D with adapter but the exposure 
variation made me move to Nikon where the exposure is more linear. I had my 
21 - 35 Elmar adapted by leitax and they shaved the cowling on the back to 
clear the mirror. Pictures with the 21 - 35 are here:

  I won't experience R lenses on the X series until I buy a N > X adapter 
when I get back to Hong Kong in the Fall. But, like Steve and some others, I 
have used my M lenses on the X using the Fuji adapter and I believe that 
experience is applicable to how the R lenses will function. With the M 
lenses the shutter lag is minimal. It is, to my estimate, the same as when 
using Fuji lenses and that means the shutter lag is very small - like an M 
series camera. The main draw back of R lenses on my D800E or on the X series 
is the lack of auto aperture when not used on a Leica R and depending on 
your shooting style and subject matter that may be an important factor. It 
is for me when shooting wild life when I want some depth of field to cover 
focusing errors.

The Fuji has an even higher crop factor than the DMR. Doesn't this bother 
you too? 

I am planning to use my Leica R21-35 on my Canon 6D. But seems like the 
moving rear lens group protrudes rather too deeply. Some users advise that 
removing the lens shroud helps but I am not convinced. Thought of using it 
on my Fuji X Pro 1 but the same worries too. Has anyone done this 
successfully? 

Otherwise the 6D gives me full frame unlike the Fuji. My 80-200/4 works 
beautifully on the 6D. So does my Cron 50, R Lux 50 and 80 as well as the 
R35-70/4. My R180/3.4 isn't as sharp as R180/2.8 and R180/4 even at 
infinity. Wonder why? The R15/3.5 protrudes deeply too. Haven't tested my R 
shift lens PA Curtagon 35mm. 

Anyone have had experience using these R lenses on the Fuji X Pro 1 and also 
happy to share his experience? 

And like you Frank, I have about given up on the M too. Seems like Fuji is 
the main beneficiary on this list. It's not that Luggers are abandoning 
Leica, just that a few are preparing for the M. Yes?
