The second image today is from the Pentax-M SMC 135 f3.5 lens. I got this one because it's not as big as the f2.8 version and it's lighter too (which to me is the whole point of the m4/3 system). Extremely well built lens and smooth action. A pleasure to use. This will be the longest lens I'll use for a manual focus lens ont he m4/3 system. After that I don't think I could hand-hold it and get a sharp image.

 

I f anybody out there has any experience with the Yashica 24 or 35 manual focus lenses, please leave me a message.
