I have lost my Konica Minolta Dynax 7d 18mm -200mm lens cap cover. Maybe you can suggest where I can obtain another one Regards Frank Cohn

Sounds like there is a misalignment internally. This will probably need to be repaired at a shop.

I don't know if I can help you. But I will try a guess. Some cameras focus on 1 point and it is not necessary the center. Maybe if you give your camera a point to focus on then keeping your fingers half cocked on the shutter shift the focus off-center to however you want to compose it, then click.
But if it was working properly before and then stopped working properly, did you lend your camera to someone, drop it or subject it to impact? I don't think anything is really wrong but I could be wrong. Have you checked the AF/MF button. Could someone may have accidentally pressed it?
If you are using the macro lens, did you check the camera's distance limits? I understand that the 7D actually focuses faster than the Canon EOS and Pentax. Canon and Pentax need to hunt that's why they take longer.

go to menu, move over to wrench, select. then move down to ctrl dial set. select aperture. now go back up and get out of menu. now you want to select "M" on your right dial.,turn your clicker knob on the front right of camera, and there you can click to bulb. hope that made sense!
