[QUOTE="JC565, post: 626505, member: 43778"] I finally got my first real camera. Took years. Ex wife wouldn't let me buy one so i had to replace her first. New wife let me buy 2! Lol Anyways, I'm not using the best lens first off. I was given a sigma 28-80 f2.8-5.6 macro. I took two shots. Both at 80mm. Subject close to camera (7 feet). Back ground objects (trees) about 70-100 feet away. Both shots properly exposed at 100 iso. First shot was at min aperture (f33 i think it showed) with a slower shutter, second was at max aperture (f5.6) with faster shutter. I used the shutter speed to make both slow 0 on the meter without changing iso since it was very bright out. Both images looked identical in the background (not in focus but little to no bokeh) The command dial does show an aperture change numerically, but i can't see it on the photo. Manually moving the aperture shows an error and the shutter won't release. Am i doing something wrong , or is it my lens, or is there a way to manually control it without the error? I really only want to make sure the camera works properly since it's an e-bay special Thanks for your input in advance! [/QUOTE]
