It's a vertical shutter, but if there was a problem there the missing section would be black and quite sharply defined.

If you are using the built in flash, at close distances it can be partially obscured by a lens hood. Work without a hood and the effect should disappear.

The K20D and K7 are big steps up from the K10D in terms of picture quality.

It strikes me that this is likely to be a physical misalignment through age. Something has worn or become out of adjustment, maybe the mirror assemply, maybe some wear in the AF mechanism.

If so, it will no doubt drift again as time goes by.

The harder you grip a filter, the more you distort its shape and the more it locks onto the lens.

If you press the filter into the palm of your hand, you apply pressure evenly and rotating your hand might release the filter. It will be covered with grease from your hand, but that's better than a filter jammed in position.

A piece of mouse mat might do very well instead, but I've onlt just thought of that and haven't put it to the test.

I usually use manual and aperture prioirty modes, both of which are fine. Do make sure though that your ISO setting is not set on auto. I would start with 200 ISO as this seems to be the optimum setting.

Far better to use flash in a more appropriate mode I think.

Good idea Glover. We have a couple of such shops around here, and the people who run them are very good.

Apparently 2MP Kodak cameras are perfect for this.
