Good value for the price as I don't think I will use it a lot.

Summary: Bought this for a trip to Hawaii and whale watching. I haven't been able to use it a lot otherwise because of cold and snow. Pictures are pretty good but I feel I need more time and practice with it. It is heavy! A tripod helps but not always able to use one.
Summary: I am no professional photographer, but I like this lens a lot. It is a little bit heavy, but takes amazing zoom pictures and picture quality is very good to my needs. I bought them used, but there's nothing to complain about.
Summary: this is a good lens if used with some skill, it is not image stabilized so the best shots are obtained hand held using the camera sports setting for a fast shutter speed. it sometime searches for focus on flying birds so I often choose to focus. I bought the lens used for less than 1/2 the price of a similar new lens, so it was a very good deal, the 500 mm allows me to reach out for bird, still and flying with favorable results, I also used a 2x extender to photograph an...
Summary: I was lucky and purchased a truly mint condition used Sigma 170-500 for use with my Nikon D80 w/grip. It has been an excellent investment. I have not used any other brand of lens in the 300 to 500mm range, where I use this lens the most (primarily for wildlife and nature), so I cannot compare one vs the other.
Summary: This is an easy to use cost effective lens which for its cost produces good quality pictures, it is light solution as you may only need carry one lens. Combine it with a 1.4x or 2x and a cropped sensor and you have an effective solution for event the most nervous of animals or birds. I take it when doing landscape as well as it is useful to pick distant features out.
Summary: Initially, I was skeptical about purchasing a used lens. However, to my surprise, it was a wonderful purchase, at a huge savings. Similar purchase would have been 3 times the cost. My faith in purchasing used through Amazon is sky high!
Summary: For some reason, I think Sigma lenses don't get ranked as good as they really are. What's more, most people think because a lens is replaced with another model the newer one must be better. To put it bluntly, this lens produces. Anyway, I bought this lens when it first came on the market in 1998. Back then, on my ElanIIe film camera, the autofocus was difficult to say the least. Then I got my first DSLR, the Canon 10D in 2002. Something was wrong here.
Summary: Excellent lens for the range and price point, hard to beat it! It has its faults, like a little softer wide open on the long end, not as contrasty as more expensive lenses, and a slower AF (but not too slow). But it gives an excellent focal range for shooting in decent lighting conditions. I love mine!
Sigma 170-500mm f/5-6.3 Aspherical RF APO review by Channel Surfer

Summary: I picked this up to replace a 500 mm Reflex. Image quality is good to very good. Good technique is a must, the field of view is too small to tolerate sloppy shots. Can be handheld in bright sunlight, otherwise a tripod is required. The tripod collar is at the extreme rear of the lens, I had to make an extension plate so that I could use an RC 2 quick release plate. Without the extension plate, the release lever on the tripod head was blocked by my vertical grip.
