I've a few Pentax legacy lenses which I use on my Panasonic G1. These are the highly rated Pentax-M 50/f1.7 and the Pentax-M 135/f2.5. Just recently I have been comparing the resolution of the 50/1.7 with that of my G1's kit, which is the excellent 14 ~ 45. With the 50/1.7 on the G1, set up on a tripod, manually focussed and the shutter set on a 10 second delay (in other words, I am not in contact with the camera when the the shutter is released) I am not getting the results I would expect from a quality lens. On inspection, the images are a tad "softer" than those of the 14 ~ 45 (also manually focussed). I know that some PK/MFT adaptors tend to cause focussing problems at infinity and mine is an ebay "cheapie". Do you think that there is a possibility that this "effect" manifests itself throughout the entire focussing range i.e. from close-up to infinity. ? In other words "What you see (in the EVF) is NOT what you get (on the sensor)"
