Product Description
Telephoto lens newly equipped with an Image Stabilizer enabling hand-held shooting for easier movement. The fluorite element and two UD-glass elements effectively correct the chromatic aberrations prone to occur with telephoto lenses. With the EOS-1v and EOS-3, the AF speed becomes the world's fastest. To reduce the overall weight and enhance portability, the lens barrel and many other exterior parts use magnesium-alloy. Also, the detachable tripod collar revolves smoothly and locks securely.

an excellent lens.......2007-12-14
This lens is very fast, it can focus very rapidly and follow accurately flying birds, this is the main reason I bought this lens. It excels in every respect, it can be hand held, very sharp even when the aperture is wide open, image stabilization is excellent and it is very fast lens, fast focusing. It can be used to photograph butterflies, dragonflies as I tested it and found that it can photograph a 15 by 10cm rectangle, thus I can say that it has a maximum magnification of 1:6.7.
This is an expensive lens, so if you think you will use it only occasionally, then I advice you not to buy it, otherwise it worth the price.
This is one wicked piece of glass........2007-11-29
The biggest factor in making this purchase was the F/2.8. I had thought about the F/4 version but losing the AF with a 2x TC on my 20D was the deal breaker for the F/4. That and I knew I'd be always questioning myself later on down the road.
I just can't believe how sharp this lens is even wide open. The weight can take some getting used to and having a grip on your body helps out with the balance of it.
One word of warning though, if your a hobbyist and decide it's to expensive to buy, never rent one. If you do, chances are you may not be satisfied with any of the other offerings once you see the results from this lens.
It's small and inexpensive..........2007-04-14
...but the lens I bought just before this one was a 600mm f/4 IS L. Given that I'm the kind of gung-ho photographer who still handholds his 600mm, I can call this lens light too!
I consider f/2.8 to be the single most important factor in buying a lens. If a lens isn't f/2.8 it needs to have some special quality to make it seem worth buying. I bought the 600mm first because I was tired of how far away the lions were at the zoo. I have a 100-400 IS L, so I knew it needed to be longer than 400mm. Once I had the 600, though, the koalas were too close. The 300mm seemed to be the perfect lens to try next, since I could bump it up with the 1.4x teleconverter to get double duty out of it.
I honestly was expecting it to be larger and heavier than it is. All in all, I'd have to call this a very manageable lens. Far heavier and more expensive than the nearly-free 75-300mm, but well worth it.
The big problems with a lens like this is depth of field. Shorter slower lenses have more of it. It is a little frustrating how little DOF is available at f/2.8 and 2.5 meters. On the other hand, that is also a major selling point.
You just can't beat this for sharpness. By all accounts it is the sharpest and fastest auto-focusing lens that Canon makes. I can't prove or disprove that, but it is sharp and it is fast.
I finally made the leap.......2007-03-14
I frequently shoot motorcycles on the street and track. Last racing season, I rented this lens several times and fell in love with it. It has fantastic sharpness and great reach--which can be augmented with the 1.4x teledapter or the occasional 2.0x. (Throw in a camera with a 1.6 crop, and you've got a looong lens.) The two mode IS and the relatively light weight make this a great lens for doing pan shots. For setups where steadiness is required, the central monopod/tripod mount helps maintain the camera's balance although having a heavy camera (1DmkIIN or a 20D with a battery grip) helps.
This lens was worth every penny.
Buy one !!!.......2007-01-19
After waiting for some time to get this lens I fianlly took the plunge, all I can say is it wonderful. It is so quick at focusing and tack sharp, plus add a 1.4 or 2x extender and it rocks !!
If you are thinking about getting one, think no more, buy it !!

This large aperture telephoto zoom lens has a minimum focusing distance of 100cm (39.4") throughout the entire zoom range. It is very convenient for close-up photography. This lens uses two ELD (Extraordinary Low Dispersion) glasses and two SLD (Special Low Dispersion) glasses for utmost correction against chromatic aberrations. This lens super multi layer lens coating reduce flare and ghost, which is a common problem with digital cameras. This lens incorporates HSM (Hyper Sonic Motor), which ensures a quiet and high-speed AF. The lens design incorporates an inner focusing and inner zooming systems. The overall length of the lens does not change during focusing and zooming, ensuring convenient handling. When this lens is used with the 1.4x EX DG APO or 2x EX DG APO Tele Converters (optional), it becomes a 98-280mm F4 AF telephoto zoom lens or a 140-400mm F5.6 AF telephoto zoom lens respectively.

Sigma Wow.......2007-11-02
At first I couldnt decide whether to buy this lense, or the Canon's 70-200L 2.8. I finally went with the Canon becasue there are so many great reviews on anything with the Canon name. After a week with the Canon I took it back, not becasue of the quality (it was excellent), but because of the price tag haunting me. I was ready to try the Sigma, and Im glad I did. Comparing the pictures against the Canons, I can say this baby performs every bit as good.
I had the pleasure of taking a safari with this lens, and the animals came out beautiful. Honestly im not looking back with this lens, it does exactly what I want, and the proof is in the pictures.
Great performance, bad quality control by Sigma.......2006-12-13
This is truly an excellent lens. Very sharp wide open, and just awesome stopped down. The focus is fast, silent and accurate. I compared this lens and a Canon 70-200 f/2.8 USM, and the result was amazing. There was hardly any difference between the lenses( sharpnes, colour rendition, AF, FTM,...) The build quality of the Sigma is great, but I believe the canon 70-200 is better. The focus ring on the Sigma feels much better.
I use it mainly for portraiture and at soccer games, and couldn't be happier with the lens.
The reason I don't give the lens 5 starts is the Sigma's awful quality control. I had to try 3 copies of this lens before I got one with the performance I expect from an EX lens.
I highly reccomend this lens, but don't be surprised if you have to try several copies.
