Reviews and Problems with Sigma 120-300mm F2.8 EX DG OS APO HSM
Showing 1-10 of 36
Slow autofocus - updated
25 May 2013
Summary: The lens I rented was twice as fast as the one I received. The HSM seems like it lacks the power it needs to lock on to a target. I plan on returning this lens. The Auto Focus is very weak and I have to manual manipulate the focal ring to get any kind of clarity. I seems the Focus Motor struggles constantly when trying to lock in. I would not recommend this lens for anyone that shoots sports on any level.
Summary: This is a real gem of a lens. Very fast (f2.8 through the entire zoom range), allowing the capture of quality images in lower light situations than smaller aperture zooms. Reaching all the way to 300mm provides the photographer with an excellent tool for sports as well as capturing candid people shots from a distance. I have found the images to be extremely sharp even at f2.8 and have not been disappointed in any way with this lens.
Summary: Works well for what I paid for it. Not the fastest focus and fails at times to focus at all when tracking bird in flight. Sharp enough, even with a Canon 2x II extender it was equal to (or in many cases better than) the Sigma 50-500 OS. Definitely would have been better if it had a focus limiter (which the new version has). Heavy, but that's to be expected from a 2.8 lens, especially a zoom.
Summary: I was looking for a relatively high magnification telephoto lens for a birding trip to Florida with a Photography Club. The leader and another member had the Sigma 120-300mm f2.8, another member had the Sigma 50-500mm f4-6.3, another had the Sigma 150-500 f5-6.3, another had a Canon 100-400mm f4.5-5.6, still another had a Canon fix magnification 400mm f4.
Sigma 120-300mm f/2.8 AF APO EX DG OS HSM Lens for Canon Digital SLRs

Summary: Heavy and big, which would be expected for a fast zoom like this one is (I believe this one weighs over 7lbs.). Heavier than the Canon 300mm 2.8 lens. The lens that I purchased is soft when used at distances beyond 60 feet and opened at 4.0 or faster. It starts to sharpen up at around 30-40 feet, or stopped down to at least f5.0. It's also sharper near the center (to be expected).
Summary: I wanted this lens for its range and its wide bright aperture. It is sharp. Not as sharp as its OS replacement but the price used was irresistible. The motor is not as fast as I wanted it to be. My Sigma 50-500 was faster motorwise but not by much. It runs silent. The lens' feel is solid. It's rings move smoothly - focusing and zoom. The lens works great with the Sigma 1.4x TC and even with the 2.0x. It focuses the same with or without the TCs mentioned.

Summary: Bought this lens after long consideration and after testing a used non OS version. Very pleasent surprise after testing on birds and wildlife. Have a supersharp Canon 100-400 but need more reach and better F plus full AF which is imposible witch Canon and a TC (unless you go for 1D). It possible to reach 600 mm and with my 7D it equals 960 mm. With the very good 3 step OS and full AF i have managed BIF shots impossible with the Canonlens.
Pros: Sharp wide open, super sharp from 6.3. Takes TC with full AF. 2x very good from f9. OS
Cons: Heavy. Inconsistent AF wich requires micradjustment. Contrast a bit weak.
Summary: I purchased the Sigma 120-300 f2.8 imaged stabalized lines a year ago and a month later in July 2011 my wife and two of our friends ended up in Yellowstone, the Grand Tetons and Jackson Hole. It was a dream trip. At that time I was shooing a Canon 40D and got a number of great shots of wildlife using the imaged stabilized Sigma 120-300 F2.8... some hand held and others from a Manfrotto tripod and 393 gimble. I quickly realized the results improved when using the tripod.
Summary: The long and the short of it is is that it is a remarkable piece of glass given the price point - very sharp at the center and very contrasty. I wrote an in depth review at the Nature, Wildlife and Pet Photography Forum ([...]). The review includes several samples - including a bunch with both 1.4 and 2x teleconverters for people who may be interested. The lens was used for several months and in a variety of situations - from great weather to snow and rain. [...

Summary: I purchase this lens in july 2011. It's an amazing zoom near equivalent to the Nikon 300mm 2.8 vr. It is a very performant lens and more versatile than a fix for a price very competitive. No regret at all.
