- Long and Heavy
The Sigma 70mm 2.8 lens gets an excellent review at [...] for its optics and image quality, and I think the 70mm focal length works well for close-up flower photos. I returned this lens only because I found it too long and heavy to keep steady while used with my monopod for garden and wildflower shots (it weighs 1.2 pounds). I just don't find it practical to use a tripod on hikes in the hills.
If I buy another marco lens I'll probably go with the Canon EF-S 60mm f/2.8 USM for my Canon ... Read More

- Incredible, true 1:1 magnification!
Simply amazing. Crisp and sharp even at the lowest f/stop! The bokeh is beautiful, and the lens feels good in hand. I STRONGLY recommend picking up a Tripod with this one, it's a little heavy on my Canon EOS 450D, and I find myself losing out on some real high quality shots cause of those shaky hands! Get a tripod and get this lens!
Rating: - Sigma macro review
This is a great lens. We've taken some great shots of flora and fauna with it, also a few sports shots. Image rendition is excellent. We use it on Canon 30D and 40D bodies. It focuses quickly and without a lot of noise. We have no complaints at all with this lens.
Rating: - terrific
terrific lens, really sharp.seems like you get a lot of quality for a fair price.i have a couple of "L" lenses, and they're great, and/but i don't think an "L" glass version of this lens would be much better than this.
