After reading this http://nemeng.com/leica/031b.shtml I was wondering, is R or R2 focus accurate enough for Nokton 50mm/1.5 wide open? Or for Ultron 28mm/1.9? The effective rangefinder baselength seems to be 24 mm.

I have a Bessa T and it works just fine with my Ultron 28mm! But the baselength is bigger - 58 mm. Here is one example shot with my Bessa T and 28mm @ f/1.9 http://www.flickr.com/photos/jsuominen/211707782/ .

It worked for me, Jari (both lenses). But you will need a well adjusted R[2], with "snap" when focusing.
The 50/1.5 has the lesser DOF, wide open.

Roland.
 
Hello Jari,

While I do not have a Nocton , I frequently use my Leica Summarit, which is also a 50mm f1:5. The focus is spot on wide open.

I believe that Cosina Voigtlander does not make lenses that are unworkable with any of their their bodies. The 50/1.5 will focus fine on the Bessa R, R2, R2A, R3A, etc. I'm guessing that they don't make faster longer lenses (like a 90/2 or 75/1.4) because they probably feel that these lenses are beyond the capability of their RFs.
 
I've shot a few rolls of film with the 50mm 1.5 Nokton on a Bessa R.

You do need to be a bit more careful with the focusing wide open, but it's not too hard to focus.

Maybe get the rangefinder adjusted to make it more precise.
 
not to threadjack, but how is it focusing a lens like the 35/1.2 Nokton on a R2A/M?
i'm sure it's a little easier on a 3A/M, but how's the .68 finder?
