Hi Arnold Impressive work you've done. I just made simple portrait shots in B/W with some above 80mm lenses - they all looked alike - except for the SMCF70-210mm, which seemed to beat both the M2.0/85mm, the K105, and A135mm (unfortunately I dont have a A*1.4/85mm) as far as sharpness is concerned. I agree that 85mm is a very pleasent focal length and the 2.0/85mm is has an attractive size. I often use medium format for Portraits for maximum resolution, though. Or the Tokina 2.6-2.8/28-70mm. Regards Jens

Are there other tests available (Pop Ph, Mod Ph etc.) ? Andre --
