[QUOTE="Ironwood, post: 71789, member: 10447"] Thanks Guys, I think I have it sorted. I took a series of shots of a printed page ( on an angle to the camera) on aperture priority, going from minimum aperture to maximum aperture. The depth of field definitely changes. Thought I had focused on 9/32, but the focus is obviously just in front of that. I am finding it a bit vague trying to focus using liveview. [ATTACH=CONFIG]15076._xfImport[/ATTACH] [ATTACH=CONFIG]15077._xfImport[/ATTACH] [ATTACH=CONFIG]15078._xfImport[/ATTACH] [ATTACH=CONFIG]15079._xfImport[/ATTACH] I didnt upload all photos, 1st is 1/60 at f5.6, 2nd is 1/40 at f8, 3rd is 1/6 at f20, 4th is 1/1.3 at f40. I think I got the order right, but you get the idea. One thing that is puzzling me is, on the camera display, the aperture readout doesnt seem to match what the lens should be. For example, on the lenses aperture ring, settings go from f2.8 to f32, while on the camera display it goes from f5.6 to f40. Is this the same thing as the lens focal length (?) changing on these dslr's compared to 35mm film cameras ? [/QUOTE]
