135mm f5.6 Comparison

Having picked up a 12 Cosina Cosinon Auto MC 135mm f2.8 on eBay - it looked unloved - in an idle moment I wanted to see how it compared to my other lenses at 135mm or thereabouts. The Cosina is not a bad lens but things have moved on since.

All shot at f5.6 on a tripod, SR off, manual focus in expanded LV on frame center. Same post-processing in SilkyPix Pro 5 on all (contrast, colour, sharpness, CA etc.) except exposure which was set individually for each.

The Cosina is a fair bit cooler than the others with pretty poor contrast. As I expected, there is little difference between the DA 50-200 and the DA 55-300 at this setting.

That Sigma 75-200 f3.8 fared pretty well. It's too bad it's not a more "pretty" lens!

Corner performance of the 50-200 is really good compared to the others.
