Sigma Lente Telefoto 300mm f/2.8 EX DG HSM Autofoco para Canon EOS USA

Comments about Sigma Telephoto 300mm f/2.8 EX DG HSM Autofocus Lens for Canon EOS:

I just bought a new complete set of pro Canon gear, two 7D's, flashes, wide and telephoto prime zooms, bag, computer -the works. But I needed a good long glass and after the set I purchased, the best 300/2.8 I could afford was the Sigma. I have used Nikon and Canon gear during my 28 years as a photojournalist and have always had a Sigma lens in my tool box.

Bought this mostly for night field sports (baseball, football, etc) and was disappointed with the lens. The same / similar issues others have noted. The focus was sometimes off (front focused) or just too slow to get the shot. I also had a problem with the lens rotating within the tripod lock ring -- after tightening the lock ring the lens tends to drift slightly. Sort of frustrating but tollerable.

I shot a night baseball game at a stadium with the Sigma a week after renting the Canon 300/2.8 to shoot a game in the same stadium so I was able to compare the results from the two lenses. While Some of my images were off with the Canon the ratio was about what I'd expect from a night game but I had far fewer keepers with the Sigma. Its frustrating to lose shots to shoddy equipment. I have returned the Sigma.

This lens would probably be ok for more stationary uses but that is not what I need it for. There is no doubt that I'll save up and buy the canon.

On the plus side, the soft case is easier to carry than Canon's hard case.

High levels of brightness and color saturation. Flare well controlled. Autofocusing very fast and very accurate, even in relatively low light levels, thanks to the speed of the lens (HSM). Sharp and detailed images. This lens gives up very little to the Canon 300L IS USM except Image Stabilization and a much higher MSRP. Tracks fast moving subjects with ease. The Canon 300L IS USM does not focus any faster than the Sigma 300 EX DG HSM. I have used both and currently own several Canon L lenses. The Sigma 300 EX DG HSM works flawlessly with the Canon Extender EF 1.4 II. Ruggedly Built and slightly more compact than the Canon 300L. I use this Sigma with a Canon EOS 1D Mark IIN and a 7D. Great lens and a great value.

I was looking for a lens that was fast and affordable.... this is it. I cannot tell the difference between the Canon 300 and this lens when I print out photos. If you are looking for a great fast lens, here it is. It is heavy, but it is a big lens.

Got mine and it was very front focus on the 40d and 1D Mark III. Sent just the lens to Sigma now a +20 is required on Mark III but images as very sharp, i am pleased. AF is slow(er) that a EF 70-200 2.8 L USM but this is not a problem with correct setting on MK3 i can work around this. I have both the sigma and canon 1.4x and i think this works better with the sigma 1.4x. There is no loss in AF speed and IQ is great as a 420mm F/4 lens. I would have given it 5 start but chances are the copy you get might be front focus.

At about half the price of the Canon EOS 300 f/2.8 this lens in 100% worth the money. I have used mine for high school, college and professional sports as well as news and events with my Canon 1D. I like that just like my Canon lenses this lens features full time manual focus. Nice for sports when your trying to focus on an area when there isn't a subject there (yet). I love using it with the sigma 1.4x converter! Images are just as sharp as without and the focus is just as fast.

Problems Encountered: There are two things that remind me that this is NOT a Canon. (other than it is black)First, and most annoying, is the lack of a focus limit switch. Without this when the lens jumps focus... GONE! The lens racks all the way trying to find the subject again. Second, the tripod (monopod) mount and bracket are really stiff and yet loose? the camera and lens don't rotate very smoothly when the lock nob is released and when the lock knob is locked the lens will still turn... Go figure? This is particularly annoying when you have mounted the camera for remote shooting in the vertical position and the weight of the battery slowly rotates the camera and lens.
