Sigma 70 mm macro

Summary: I like this lens a lot. It's my first prime lens and also my only macro. My reason for giving it 4/5 stars has to do with autofocus issues. Often, the lens spends several seconds hunting for correct focus. It gets tiresome if you're doing a lot of shooting. However, the build quality is excellent. I've read that the optical quality is outstanding and surpasses the resolution of my Nikon D90's sensor.
Summary: Initially I thought I bought the best lens so far. It was sharper than my 50 mm Canon f1.8 lens. Then one day while I was shooting I forgot to tighten one of the legs on my tripod. My camera with Sigma 70mm attached to it fell down on the wooden floor. The lens had the hood attached to it. So it didn't hurt any of the glass part or the front part.
Good for product photography, but not for 1:1 macro

Summary: I purchased the Nikon mount version of this lens, primarily for product photography in a tight space. It works really well for that, as it focuses seamlessly from infinity down to 1:1 macro magnification with no breaks, or gaps in the field of view, that you might get using a macro ring. And it doesn't make you switch to a special "macro mode" as some zoom "macro" lenses do. This lens simply allows you the freedom to shoot at literally any distance you want.
Summary: I recently bought this lens for myself for a birthday present. I was iffy at first since it's an "off brand" but once I got to using it, I couldn't be happier. It's a little harder to focus clearly than a Nikon lens, but it just makes me try harder with my skills!
Rediculously Sharp, Accurate AF, Great Focal Length on crop sensor!!

Summary: Let me first echo what just about every other personal and professional reviewer has said about this lens. "This is probably the sharpest lens in my bag or that I've used." Yes it is sharp, I mean very sharp. This Sigma 70mm macro out resolves my 12mp Nikon d90 easily. My computer screen and d90,(nice screen), usually pix-elate and fall apart long before the detail that this lens resolves. Any shortcoming in image quality is mostly attributed to user error.
Summary: A great lens for those working on a budget. I've used it in many different situations, out in the sun at f/8 and in extremely low light at f/2.8 higher iso. The pictures always turn out very well. Of course when compared to the nikkor, it has slower AF function in low light and misses the proper focus points sometimes, and is a little on the loud side with the AF motor, but overall it's a great lens to have especially given its price.
Summary: I purchased this lens about three months ago so I've had plenty of time to give it a thorough testing. Pluses: - this lens gives me nice sharp pictures from f/2.8 to around f/18 - great soft bokeh at f/2.8 - unlike the reviewer of June 2009, my lens DOES shoot at f/2.8 even when I am 2-3 inches from a subject at 1:1 macro - very solid construction. I had the lens roll off of my fanny pack about 4 inches to a gravel surface. Didn't bother it at all.
Summary: 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.
Summary: 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.
