Now enjoy that great lens  Last week I was testing out a lens I just purchased to use it for the "single in March", the A-50 f2.8 Macro on my K7. Always used focus confirmation with good results on a manual focus lens in the past. What I was seeing was a blurry image but focus was confirmed. Well I trusted the camera and lens combo to do its job. Took a few photos, processed them, photos were tack sharp. Yah, the diopter adjustment got bumped over to the left 4 clicks. The diopter is one of those set it and forget it cause how the heck could it change when it is a pain to move it with my big digits. ..it happens Lesson learned. Don't sweat it until you see the results and then look for possible causes. Clarence | |

| Originally posted by str8talk83 I thought there was a problem with the Lens elements when I first received the lens because everything was blurry. Then I noticed today that I couldn’t see any of the viewfinder indicators, so I adjusted the diaptor of the viewfinder on the camera and discovered that it was way off. and as you can tell a few of us may have red faces from time to time I know I do | |
