I'm having some problems with my 10D at the moment. I wear glasses sometimes when i use a computer or read but i have lost them at the moment. I don't use them for photography and don't really want to.
Last night i was taking some bug macro pics from a tripod and using the timer (I was lucky enough to find a large fly and a bee basking in the sun who let me get very close!). Through the eyepiece, the shots looked in perfect focus and i started snapping away (I had manual focus on due to light levels). I took maybe 100 shots and all of them were out of focus by about the same amount.
I checked out the dioptric adjustment reference in the instruction manual and it says to adjust the wheel until the AF points look sharp. The problem is that they do look sharp and i cannot really seem to get them sharper. Obviously when taking such a close macro shot, it is crucial that the eyepiece shows what the camera takes. Does anyone have any ideas i could try?? |

Try putting the camera on a tripod, lock it to center AF point focusing, and auto focus on an easy target (bright, high contrast, etc). Then adjust the diopter so that the whole scene looks sharp.

Ideally, you shouldn't adjust the diopter with a lens mounted on the camera. Your brain will tell your eyes to instinctively try to look at the image being projected on to the focusing screen to see if that is sharp (and the sharpness of that image is controlled primarily by the focus ring on the lens). By removing the lens and pointing the camera at a blank, well-lit white wall, you'll be able to move the diopter adjustment while concentrating on getting the etchings on the focusing screen as sharp as possible (as well as the LCD displays visible in the viewfinder). Once you've done this, your diopter adjustment should be set properly.
