A Quirk of Aperture (Three Photographs)

Shooting with a cropped sensor (e.g. one that is one half the size of a full frame camera) has a few implications, one of which is that you need to think about apertures multiplied by the crop factor. This means that small sensors have greater depth of field at the stated aperture than a full frame camera would at the same aperture. Now if you look at the second and the third photograph, they were taken at F5.6 and F5.0 and the difference should be quite noticeable as it’s a full stop difference in full-frame terms. I hear someone say “why compare it to full frame if I am not using a full frame camera?” Because for close-up and macro photography you have the kind of flexibility that full frame cameras do not offer (and it’s a myth that you lose out on great out of focus backgrounds).
