Sigma APO 120-300mm F2.8 EX DG OS HSM (136-101) boasts Optical Stabilization (OS) which is critical to equipment sporting this focal range allowing for hand-held tele-photography and the use of shutter speeds approximately 4 stops slower than would otherwise be possible. Its includes splash-proof feature preventing dust and precipitation from getting inside the lens. One SLD and two FLD glass elements provides maximum correction of chromatic aberrations.
The super multi-layer coating reduces flare and ghosting and the lens design incorporates an inner focusing and inner zooming system to ensure sharp images throughout the entire zoom range. Improved optical performance provides excellent correction of sagittal coma flare and ensures ultra-high resolution, comparable to a fixed focal length lens. The HSM (Hyper Sonic Motor) ensures quiet and high speed AF, while allowing full-time manual focus override. A truly unique product which is a rarity in the photo industry, this lens is the only lens of its kind on the market; a professional zoom lens that also features a fast aperture.
Most professionals own the standard 300mm 2.8, but they also have to carry a shorter zoom lens for those times when the subjects move closer. That means fumbling around switching lenses or carrying a second camera body. The amazing Sigma zoom lens let you instantly determine the picture composition you want without having to change your vantage point.
Imagine photographing courtside at a college basketball game and having the versatility to zoom in on a player's face or hand and then instantly zoom back to capture the entire player making his shot. You can do it with the 120-300mm F2.8 EX DG OS APO HSM. The aperture remains constant at F2.8 throughout the entire zoom range. The addition of the optional APO tele converter produces an ultra telephoto zoom lens with AF
I've had this glass less than a week and haven't had the chance to put it through its paces but the few images I have captured are amazing. I'm looking forward to using this on the pitch this summer and capturing some great images. In all honesty, I was hesitant to purchase through Adorama because of a bad past experience. Wanting to give them an opportunity to win me back I went with this large purchase. They did not let me down. The package arrived sooner than anticipated and well protected.
OK you know a 300mm F2.8 is going to be heavy, that is a given and since you know that up front it is not a negative. First of all I needed this for a trip to Alaska, Adorama got to me a day early. Woohoo to them. The lens is remarkable for several reasons. Primarily because it is sharp through its ZOOM range, and also because no other player has a zoom in this range and at this speed. This is important more often than not when the action is coming toward you and you have have no room to move back-this would stop a 300mm prime in its tracks, not so this Sigma. Also of huge importance is the USB computer adjustments. Know you are shooting birds then prior to leaving dial in the focus range for 100 meters and up, then the lens will only focus in that range and up greatly increasing an already fast auto-focus. Tank like build is another plus. Personally I love the black color-it just matches my Canon bodies. Metal hood too! I even appreciate the 'S' for sports symbol embedded into the lens body in a classy silver. p.s. Tripod or monopod required.
I rented a new Nikon 80-400 which I thought was going to be my go to zoom when I needed a longer reach. The 80-400 didn't impress so I continued my search. Other reviews on the new 120-300 Sport from Sigma convinced me to take the plunge and buy it. I liked the idea of having a fast (man it'sheavy) tele zoom and being able to add a 1.4x TC and still have a moderately fast f/4 400mm+ focal length. A 600mm f/5.6, if IQ was good enough, would be icing on the cake. So I ordered the two TC''s with the lens. Ok, the lens is big. Its heavy. Those are the negatives. But a lens this fast and this good by any manufacturer is. The build is on the plus side of excellent. AF is super quick, even with the 1.4 TC, less so with the 2.0 TC.This lens is very very good when used with my D800. At 300mm from 2.8 to 8 it maintains its sharpness/detail/IQ or whatever you want to call it (I'm not a peeper), all I know are the pictures are clear, detailed, correctly exposed, have great contrast and are very pleasing to look at. They compare favorably with the results from my 200mm f/2 VR and thats saying something. I haven't gone beyond f/8 yet but expect it to work well with the smaller apertures as well. The OS works very well but I tend to bump my ISO up to 800-1250 to maintain a quick shutter. So I'm shooting at 1/1000th or more although a few times I have dipped to 1/320th and the OS kept things tidy. Early on I switched to the 1.4X TC and everything above is ditto when using it. I have a difficult time selecting "native" shots from TC shots without using Lightroom. I'm using LR with 3:1 mag too when I evaluate these photos. The last couple of days the 1.4 TC has just stayed on the lens. I am impressed. This is my second Sigma, the first being the 35mm/1.4. That one was all I had heard it was which to be honest was another reason I went ahead an bought versus rented one to try. I hoped (expected?) the 120-300 to be good, honestly not this good, but good. Oh, the 2.0x TC results as it turns out is wayyyyyy better than hoped for. Totally useable. There is no question that the results with the TC 1.4x at 420mm and f/4 beat ANYTHING the 80-400 produced at any aperture. Maybe I got a bad rental copy of the Nikon. Its possible, but the 120-300 IQ and available options (fast 2.8 zoom up to usable 600mm) with a TC is what I was looking for and I got it. I've also taken many shots from 120 up thru max zoom and the results stand. I bought this more for range which is why my review has concentrated on the long focal length. Now, if the hummingbirds would just come around the yard.
Pictures are tack sharp and color fidelity is superb.
I have been trying the lens out at horse shows and on wildlife and birds. The focus is fast. The pictures are crisp, with no vignetting or chromatic aberrations noted. I did notice very slight vignetting at the furthest zoom when using the 1.4x teleconverter, however it is minimal and easily fixed. It is a large lens and while it could be hand held, it is too big for me to personally hand hold it. I mount it on a monopod for the horse shows and a gimbal head for wildlife/birds. I have a Canon 1dx and love the fact that this lens is weather resistant as I do have photoshoots out in the rain (part of being an Oregonian).....
Lens is used with a Canon XSi, a basic DSLR, to shoot birds. Lens is mated to either a sigma 1.4 X or a 2.0X converter. After early shots and tests the following is observed: AF is fast, quiet and dead on; sharpness or clarity of detail after zooming in to just before pixel stair stepping is superior to the canon 55-250 with identical framing (canon at 240mm and sigma at 120 w /2.0X). I am very pleased with the lens but recommend a teleconverter to justify it. It is sharper by far than the canon package lens, but for that much loot I want more brought to the party. The lens is heavy. My new tripod claims 15 lb capacity and it seem just adequate. I have the product version that precedes the ' sports' version ( which has a /s added to type and cost 1K$ more). I recommend this product but suggest getting a converter. F2.8 allows it.
Hello, I had the chance to try it in two different stores and the result is same: very high quality pictures. I took some shots with my 5dMKII and the sharpness is excellent at 2.8. I also try my Canon 2X III and yes the result was amazing. This give you a 240-600 f5.6 lens perfect for wildlife and day sport action. I plan to buy it into next 3 month. I also try the Canon 300 2.8II in store and after photo comparison, Canon is a little better but 3 times the price of the Sigma.
Sigma has finally done it. They've gone and made a lens that can top Canon and Nikon. Until now Sigma lenses, in my opinion, has had equal quality optics. This 120-300 2.8 OS gives image quality better than Nikon and Canon. The detail color produced are amazing, not to mention the beautiful bokeh.
If you want the very best possible image quality , you will need a prime lens. Does not matter if you shoot Canon, Nikon .... A zoom is very convenient when at the sidelines for photos but if using for cropping and enlarging for action photos of events for clients only a dedicated prime from camera manufacturer will give you the best quality you are looking for . The MTF charts look really good on some non dedicated lens but just don't compare to real tools. Let's face it, for the money, GET THE REAL THING , just pay a little more. The difference will amaze you . There is just no free lunch when it comes to lens.
was defective after 1 month had to send in for repairs. Adorama would not take it back. Customer service off shore, very disappointed about that!! Very slow to focus IMO
