There is a circular hard black shadow on the top left at 6mm and at the top left and right at 10mm. It seems like he only gets these shadows when the focal length is wide 6mm and 10mm. I'm not sure, but it seems to be catching part of the lens barrel. Nothing is in front of the lens and the cap is hanging way below the barrel. https://photography-on-the.net …p?p=2962090&postcount=534

Without those it is hard to say.The focal length of the lens can be 6mm and 10mm but the equivalent focal length (in 35mm terms) is found by multiplying the lens' focal length by some crop factor (1.6 on Canon APS-C cameras). Just like when an EF-S lens has a focal length of 18-55 but when used on a Rebel XT the 35mm equivalent focal length is (18-55 * 1.6 = 29-90). Excellent point! I have forgotten about the crop factor! I have edited my original post and have also posted some photos. Thanks for your help! https://photography-on-the.net …p?p=2962090&postcount=534

| Permanent ban I'm not sure if either of the last two posting has clearly read my original post, but this is not a Canon SLR. Therefore, I can't send in the Canon lens nor is it a lens hood. I guess I will have to send the "point and shoot" Minolta Dimage Z5 in for service, unless anyone else has commetnts.... https://photography-on-the.net …p?p=2962090&postcount=534

Before sending it in see if you can email the Customer Service department these shots. Maybe they can tell you what might be wrong before you send it in. Mike, The Keeper of the Archive
