It's in an Asian language. There are three charts. Chart 1 compares measured focal length, measured max. aperture, distortion, and EV (EV light loss?). Results are from Modern Photography. Chart 2 compares center and corner resolution. I can't determine where the results are from; presumably Modern Photography. The Pentax 50/1.4F kicks butt. Chart 3 compares center and corner contrast at a fixed resolution, as measured by Amateur Photographer. I wish I knew which magazine rated the Rikenon P 50/1.4 above the new Contax. In the tests summarized here, it's nothing special. Paul Franklin Stregevsky - This message is from the Pentax-Discuss Mail List. To unsubscribe, go to http://www.pdml.net and follow the directions.
