Probably an oldie but goldie, but here goes: I used to have a 100 mm macro lens for my Contax system and am considering getting something similar for my 10D. I'm somewhat torn between the 100/2.8 macro and the 180/3.5 macro. I'm aware of the obvious tradeoff regarding price.
I would definitely appreciate the bigger working distance and smaller field of view (fewer background distractions) of the 180, but I'm a bit concerned that the depth of field might be rather shallow due to the longer focal length. Obviously, part of the point of macro photography is to isolate the subject via shallow depth of field, but still... Have any of you tried the two lenses? What has been your experience? Is the depth of field for macro photography dependent on the lens focal length or the magnification?
