Images taken with a GH1 and Konica Hexanon 57mm f/1.2 adapted lens. My copy is an early version with the silver f-stop ring. Probably from the late 1960's. These lenses have a habit of "yellowing", due to the rare earth glass, but my current copy has glass that is nearly white. Apparently, you can "whiten" the glass by leaving it uncapped in a very sunny room (not in direct sunlight) for a few weeks... The three pink rose images are taken wide open at f/1.2, about 12 inches from the rose. The red/orange buds were taken at f/2. The 57mm is fairly sharp wide open, but with a lot of "glow"... the glow gets less and the image gets sharper with each 1/3rd stop, and is crisp and clean by f/2.4-2.8. f/2 is a nice compromise of sharpness with soft bokeh. These are processed in Lightroom 3 beta 2, slight levels adjustment and slight vignette added (the lens does NOT vignette). Color and saturation is right out of the camera!
