Hello Leicaphiles, this is my first post here. I am currently using Pentax gear, mostly "limited" primes, and including some very nice older lens. However, i feel i have a weak link in my lens lineup at 135mm. I am currently using a Pentacon 135mm f/2.8 lens, in M42 mount. This lens has 18 aperture blades and is nicknamed "the bokeh monster". Indeed, it produces excellent bokeh even stopped down, and is very sharp by f/5.6, especially at longer distances. It is of east German construction, all metal, with precise (huge throw) but rather stiff focusing. But i am considering the Leica elmarit-R II 135mm f/2.8 as a replacement for it, mainly for its performance wide open at tight portrait distance, where i find the Pentacon lacks a little pop. I would adapt it to Pentax K mount using a Leitax converter (probably blasphemy on this forum, please forgime me!).
I have seen some impressive pictures with this lens on various online sites, but would apreciate your opinion of it before committing.
Thank you,
Miles
