Thanks, yes, I checked the camera and the lens with a strong flashlight and it does not appear to have anything other than the expected perhaps tiny bit of dust (I didn't notice much)...there is nothing growing on it I also did a test with the makeshift groundglass (CD case with magic tape on it) and it appears to be OK. I also tried clicking the shutter on a tripod and holding it and I did notice some motion when I clicked holding it vs. virtually none on the tripod...that probably explains why the tripod test images did not have the sharpness issues of the previous (handheld) images. Perhaps I'm not steadying it enough when I hand hold it. I did have a thought that perhaps I should consider a monopod as it's less cumbersome than a tripod and would help?
