Not a great shot, but I managed to snap it and thought I’d give it a share. the 20D on her shoulder made me giggle a little.
Olav, thanks for the feedback. To clarify the question further – on a 50D with 1.6 crop, what are the pros and cons of 60 vs 100 mm focal length? Then, which particular lens do you like?
Haven’t played with the 60mm, but using Kat’s 50mm as a comparison, I like the shorter focal length better (I think the 60mm Canon lens is an EF-S so IIRC you don’t get the crop factor?). Ideally, I’d want both, but the 50 gives you a bit of an easier time, especially when chasing bugs around. The drawback is, of course, that you need to be closer to get a full-frame shot.
The Sigma 50, Canon 60, and Canon 100 are both 1:1, the former with ~7.5″ minimum focus vs the 100’s 12″. But remember that’s also to the sensor, not to the edge of the lens, so either way you can have the glass jammed right up on the subject if you want.
Short answer is, if I were hard-core macro, I’d probably want the 100mm. A little patience will yield a much tighter shot, or an equivalent shot from a little further away. If I wanted something more versatile, that also did a good job doing macro, I’d grab either the Sigma 50, or Canon 60. They’re pretty equivalent spec-wise.
This was with the 100mm Canon, uncropped. so your frame is limited to roughly three grains of rice.
This is about as close as I’ve been able to do with the 50mm Sigma. Granted it wasn’t in the studio. It’s also possible I could have gotten closer were I not concerned about her attacking my camera (again)
