 The SIGMONSTER Apr 01, 2008
By Michael A. Hays
This is an awesome lens and is a real must-have for birdwatching and other nature photography. The zoom range is extremely flexible and the f-stop reasonably fast, but keep in mind that this is a very, very specialized lens. First of all, yes, it is gigantic! This is not something you'll be carrying around day-to-day. It can be very challenging to get sharp pictures at focal lengths beyond 400mm or so. You MUST MUST MUST use a sturdy, high-end tripod and gimbal head. This will also preclude the "downward fall" described in another review. The lens alone is very heavy, and once you toss in a sturdy tripod you're talking 25+ pounds of equipment at a minimum; this is really going to limit your mobility and affect the way you shoot. It takes a lot of forethought to use this lens, but I prefer to think of that as an advantage.
When used properly, this lens has fantastic image quality -- very sharp, excellent contrast. When I say sharp, I am talking L-series sharp, even wide open. The HSM focus speed is fast, perhaps slightly slower than Canon's USM but not appreciably so. The only thing it's really missing is image stabilization (or optical stabilization, as Sigma calls it), which would really help out on those long shots. This is a minor limitation, though, to a great lens. If you have the discipline to learn how to use this lens properly (and if you can afford it!), you'll reap some great rewards.

Perfect Lens In The Super Telephoto Zoom Range Feb 08, 2011
By Gary Mayo
First off, this lens is no toy. It is a serious tool. One of the reviews here is not taking into account the persons ability to know how to use a lens like this. If you do not know how to use the lens, the lens can be no better than the photographer.
This lens requires support. That can be in the form of a heavy tripod and gimbal head, or it can be in the form of bean bags. Bags over the lens and well as under it.
A 800mm lens can see the effects of a 3 mph wind going gently by. Would not doubt it would see the effects of a bug landing on it. This lens needs substantial support. It could also benefit from mirror lock up, and a remote shutter, or a delayed timer.
If you are not going to take the time to learn how to use it, and then take the time to set it up, do not bother getting this lens. It will do you no good at all. Stick with the kit lens that came with your camera.
However, if you are a pro, this is a serious pro lens. It will knock your socks off! No other lens on the planet will do what this lens will do. 300-800mm Zoom in a constant f/1:5.6. Simply a dream lens!
As for that other reviewer, enjoy your kit lenses.
 Not for a Pro, but definitely for the rest of us May 24, 2012

Fantastic lens. Soft at the far ends. It is the Sigmonster for sure. It's great for those that are looking to take some fantastic shots at incredible lengths, but not for those that plan to sell those shots to National Geographic (let's face it, most of us aren't). As such, a very fun lens. The focusing does not change the length of the lens which was a nice touch. It would be useless if not for this feature, but they definitely thought about the product. It's a great lens though. Those that are complaining that it just takes soft pictures are VERY picky. I am VERY picky which is why I sold my copy last month, but I can't say that I'm a ton happier with my Canon 600 IS II. It does take solidly better photos, but there is no versatility.

 unhappy Apr 05, 2011
By unhappy
I read with interest the three previous reviews. Unfortunately, I have poor results with this lens. My particular lens required warranty in the first month after purchase. Subsequently, I have returned this lens to Sigma two additional times. The picture quality has gotten worse each time repairs were made, to the point now where the lens is unusable. For my particular type of photography, the advertisements for the lens indicated that it would be a winner. The folks at Sigma have proven to be a huge disappointment.

The Lens which Ate my Dog Dec 22, 2011
By C
I got this lens for avian photography, with high hopes of its quality and performance. Unfortunately, when they were shipping this lens to me, UPS forgot to feed it. When it arrived at my house, I unpacked it and did the usual new lens tests. I let my dog run in an open field to test the lens speed of focus. As soon as I pressed the shutter, its giant mouth opened to reveal gaping teeth. It chewed my poor animal to bits, and swollewed him away. I give this lens 5 stars because now I no longer have vet bills....
