Amazon.com Product Description
The Sigma APO 70-300mm f4-5.6 DG Macro Lens for Canon Digital SLR Cameras is a telephoto zoom lens with tele-macro functionality. Optimized for digital cameras, this high-performance lens has two Special Low Dispersion (SLD) glass elements in the front lens group and one in the rear lens group. It is able to shoot with maximum magnification 1:2 at the focal length of 300 millimeters. It's the ideal lens for portraits, sports photography, nature photography, and other types of photography that frequently use the telephoto range. The multi-layer lens coating and lens design reduce flare and ghosting, which is a common problem with digital cameras, and it also creates an optimum color balance through the entire zoom range. High optical performance is demonstrated throughout the entire zoom range. The lens features a switch that converts the lens to macro photography at focal lengths between 200 millimeters and 300 millimeters, with a minimum focusing distance of 37.4 inches. In normal mode the minimum focusing distance is 59.1 inches at all zoom settings.

 Love this lens July 27, 2010
Manuel Calavera (Ventura County, California)
I have a Nikon D70. I have used the 18-70mm that came with it and sold it to get the 18-200 which is an awesome lens. I just bought this Sigma because I wanted a macro lens to take some close-up pictures for work as well as my praying mantis and a few lizards. For the price, this lens really delivers. The macro feature is pretty much all I have used it for so far because that's the reason I bought it, and it works great. It feels solid, too. The only negative thing I have noticed so far is that I often have a hard time getting the autofocus to focus correctly in macro mode. Many times it will focus all the way in, all the way out, and stop because it can't figure it out. When this happens I just use the manual focus. However, for this price, I won't dock it a star because it is just ridiculously inexpensive.
Great lens! July 13, 2010

Terrific lens ~ well balanced. While photos are dependent on the photographer, this was a much appreciated tool for my husband's camera bag & the included case was well made too.
Excellent Results for a Great Price ! July 10, 2010
Renato Aranha (Sao Paulo, SP Brazil)
I was afraid about the result of the pictures, because the huge difference of price between Sigma and Nikon lenses, but I am very satisfied with the results I am having. Definitely the Nikon luminosity is better than Sigma, but certainly will not make a big difference if you are not a Pro! I recommend this product and I am sure you will take great pictures, besides the excellent macro zoom offered by a 70-300mm lenses.
Seat back, relax and enjoy the pictures!
Perfect companion for D40 June 13, 2010
M. Pentecost (Sacramento, CA)
This lens just arrived in the mail.
I've had a D40 for about 2 years now, and have been only using the stock 18-55 lens that comes with the kit. The postman dropped off the lens about 30 minutes before we were set to take our little toddler to a children's theme park. Perfect timing.
While I have always loved how my D40 takes pictures, after a few hours with this lens, I don't know if I'll ever use the kit lens again. This lens feels like I have taken the blinders off my camera, and boy now can it breath. With outside shooting, and several of my pics in the upper 200 area - I used shutter priority mode, and set the shutter speed to 1/500, set max iso to 800, and wow was I impressed with the results. I could frame the little guy just perfectly while he was on his little rides, and the photos came out way better than anything I have done before (shows how much composition can effect a photo).
At 300, this lens will only open up to F5.6 - so I would suggest bumping up the iso or getting a tripod if you are going to be shooting in that range mostly.
Here are some main things I noticed about the feel and function of the lens:
1. The lens ads considerable weight to the camera over the stock 18-55 lens (DUH).
2. The zoom is not as smooth, but is still very smooth, especially considering the heft of the lens is so much more than the kit lens.
3. The AF is louder than the kit lens, but is fast and more than enough. It feels like a tank, and when it does AF you can really feel it snap into focus.
Overall, I really really love this lens. I'm not in denial - I'm not a pro photographer, and I never will be. I will alway just be a normal dad that happens to nerd out over his gadgets. But with this lens - I'll blow away those point and shoot photos ... lol.
 Sigma 70-300 Motorized Zoom lens for Nikon DSLR June 3, 2010

I wanted to upgrade to a longer zoom from my Nikkor 55-200mm lens, and it sounded like this was going to be a great substitute for the Nikkor 70-300 zoom lens which is way more expensive. Out of the box it looks and feels great, and the magnification is excellent. However, I hadn't realised how much difference the VR - vibration reduction - on the Nikon makes. I take a lot of handheld sports and landscape shots. The sigma lens produced photos that just weren't clear enough for me. There was a lot of blurring, presumably from camera shake. This was unacceptable so I had to return it. I'll just have to spend the extra $$$ on the Nikkor with VR.
