It doesn't come off my camera much.
I got this lens because I didn't really own anything close to this range except for the kit lens (good but not great and not f/2.8).I do own a 15mm Canon Fisheye but it does distort quite a bit even on the 20D and I don't like to have to correct in Photoshop each time and I wanted a wide lens.I wanted something wider, that could capture lots of light (I do allot of ambient and low light photowork) and I wanted something versatile (on a 20D this is really a 24mm to 56mm --- great working range).
Not what I expected...
I shoot with a Canon 20D and have used the Canon EF 28-135mm f/3.5-5.6 IS USM lens as my wide angle option. When preparing for an extended stay in Budapest, I decided it was time to invest in a faster, better quality WA lens. I reviewed the lens lineup at the Canon website and decided on the Canon EF 16-35mm f/2.8L. As an L lens owner, I was confident this lens would be a great addition to my lens lineup.
16-35mm vs. 17-40mm, both Super, but what's the difference?
Well, besides a whole bucket full of money, one of them lets you take photos in lower light, okay, that's obvious. The 16-35mm is a bit heavier, but not so you'd notice, unless maybe you were carrying it around all day, without eating and you're a bit over the hill. So why pay the extra money, unless, of course, you do a lot of shooting in the early morning and late evening?

Sigma APO 80-400mm F/4.5-5.6 EX DG OS Lens for Canon SLR Cameras
Very pleased with this lens.. espcially like the OS for hand held shooting. Photos are sharp.Debated betwwen this lens and the Canon 100-400mm... Selected the Sigma based on reviews and cost savings of $450.Works well with my Kenko 1.5 teleconverterfor a Zoom of 600mmthough the auto focus is slow with the Kenko unit.

Not a bad lens, not perfect.
I purchased this lens in lieu of the Canon 100-400 L OS, to save a little money.It wasn't a bad decision, but I will qualify it with the following note.I've used this lens on the Canon 30D crop sensor and on the 5D full-frame sensor.This lens works much better on the crop sensor.You'll get more telephoto and less distortion. On the full-frame 5D, the lens is at its limits on vignetting most of the time and I've found the results to be mostly unacceptable.It produces reasonable sharp shot and the OS works very well.It is a slow focuser though.Build quality isgood and solid, though a bit heavy it isn't difficult to carry around and use.Final thoughts...if you are shooting a crop sensor camera, this is an excellent walk-around lens with good range and good results.If you're shooting full-frame, I'd avoid it.

Excellent Value
I was considering both the Canon 100-400 and this lens. I opted for the Sigma for cost and I very happy with it. Though it's not a light lens, with the OS, I can hand-hold it even with a 1.4 extender in daylight. I prefer the ring zoom over the Canon push-pull because all of my other lens have it. ...

You get what you pay for
This lens in just ok.It is a little soft at the edges and at wide apertures.After using it for a few months I sold it to buy a Canon 17-40 f/4 L.The Canon is a stop slower and a couple hundred dollars more, but the images are sharper and it is weather sealed.I would invest the extra money in a Canon lens.

Good Lens, but Very Fragile
I was given this lens as a gift from my father after he'd used it for about 5 years.It broke on him twice before he gave it to me, and it broke on me shortly after he gave it to me--the aperture would stick and cause error messages on my EOS 10D.Between he and I, we've sent it off for repair service three times.When it works, it works well.It is sharp, had good color and takes good pictures.In fact, I really enjoy it.Be prepared to spend a lot of money on filters, though.At 82mm, good filters don't come cheap.This is a good lens, but it is likely to give you headaches.Consider buying Canon's 16-35mm or 17-40mm first; it may be worth the extra money.

One of the best Sigma lenses
Quite a sharp lens, did some very good shots until I replaced it with Canon 16-35 f/2.8. Overall I was very happy with it, the tiny little problem it is a very fragile lens (like most of Sigma lenses), and it needs a very special treatment, also the size of the filter is very big, makes it very expensive to buy 82mm C-PL for example. ...

Versitile, heavy, need tripod, but good
There's no substitute for a good piece of glass.
Bigma gets the job done well if you're thogh to carry it

Great product - TERRIBLE CUSTOMER SERVICE
I bought this lens in October and loved it. It's great when it works, but the manufacturing sucks, and the lens came apart in under a year. I sent it in for warranty repair and got a bill. I spent HOURS on the phone with Sigma's repair department and, after being passed around from technician to manager to Sales Manager, I was told they'd pay for the repair labor, but I had to pay for parts. They were totally unconcerned with customer satisfaction, totally unconcerned with the reputation of their equipment. They just weren't going to fix the problem with the piece of equipment I paid $800 for. Sigma makes a great product, but isn't at all concerned with customer Satisfaction ... Read more

Had this camera for a year and love it
I researched several cameras and finally chose this one not just because they make great lenses but the lense mount. Theirs is metal while Cannon, Nikon, etc are all plastic. This is not only cheap but flimsy. It takes great pictures and no one else gives you better value than Sigma considering the two lenses and bag. The bottom line is it takes great pictures and has lots of features. I don't care that some have said it a good starter camera--its like a bike. Lance Armstrong would win on any reasonably good road bike. Period.

Sigma
Buying this camera was a total mistake.I had it for 3 months and it started using batteries, $36.00 worth in two days.I returned it to Sigma on December 10th and kept calling them.They told me they were too busy to look at my camera and call back at the end of January.I called again and was told the manager would call me, he never called.I then sent an email and they never responded.I went out of town for the weekend and came home and my camera had been left on the porch for 4 days in the cold and rain.I have never seen such poor customer service.Not quite sure about the camera yet because I wasn't able to use it very long.

The sharpest images you can produce
I'm a bit late in writing this review since I've had my SD9 for one year.
amazing picture quality
i have had this camera for almost 2 years now and am still in love with it.i use the EX series 15-30mm lens and there isn't a situation i have found where this camera doesn't kick the [...] of any other digital camera (except for maybe the new SD10).i have a friend with a Canon that cost a ridiculous $9,000 and her pictures look like junk in comparison.i recently took a photo i took with my SD9 at a canyon in new mexico and had it blown up to over 3 feet wide.of course, the file size is absolutely huge, but the print out is stunning.you cannot even see the pixels.
Inferior color
It's hard to get decent color with this camera and its software. Skin tones come out too yellow. Resolution is good. ... Read more

Pro Camera
A few things about this camera: I have been using it in pro work for almost two years, and it is just that, a pro camera. It is bare bones. No toys that you will find on many larger names. I, personaly, don't miss those toys (maybe I would like a small popup fill flash every now and then...) so long as you don't mind or are already hauling a full bag of toys along with you. I have the TTL flash made for the camera by Sigma, and its 'ok' with some post editing. Good reach and power, but will sometimes not talk to camera and need to restarted.
A JAPANESE WORK OF ART!!!!!!!
I WANT TO WRITE A REVIEW ABOUT THIS CAMERA BECAUSE I BUY IT A FEW DAYS AGO AND I WANT TO TELL YOU THE REASONS OF THIS PURCASE.
This camera is past it's prime
The review "A great camera with a few drawbacks, February 26, 2004 Reviewer: A customer (St. Paul, MN USA)" is exactly what I would have written a couple of years ago when I first bought this camera.In the right conditions, especially landscape and close up photography you can produce some really spectacular images.Indoor family snapshots with this camera are no better than average, but never-the-less adequate.Overall I got some great use out of the camera.
