Help, please! I currently have a Canon 60mm macro lens, but am thinking of trading it in on the 100mm version, mainly because I would not have to get as close to the subject. However, the deciding factor for me will be the depth of field that can be achieved. Can anyone give me some advice here? The closest focusing distance for the 60mm lens is 20cm, for the 100mm lens, 30cm. If I set the aperture at f/16, and took identical photos with each lens (I realise I would have to make some physical adjustment, or crop an image to achieve this), which one would give the the greater depth of field?
I'm curious myself and hope somebody had a chance to use them both and can give us a scoop. From many reviews I've read, apparently the difference in DoF between those two lenses is negligible but most people preferred the 100mm for a more comfortable distance to the subject.
The longer the focal length the shallower the proportionate depth of field, ie the 60mm would have more background in focus than the 100mm. I don't have a 100 macro to post an image for you, but my 180 macro has about a DOF of about 3" @ F16 : ] best...jerry
