Sigma 120-300mm f/2.8 overview

  • 1Description

The Sigma 120-300mm f/2.8 DG OS HSM Lens for Canon is a telephoto zoom lens featuring a fast, constant f/2.8 maximum aperture. This lens is the first lens designed under Sigma's new Sports line of lenses, making it well-suited for fast-moving subjects such as wildlife, nature, aviation, racing, and other similar situations.

Featuring a dust- and splash-proof construction, this lens is ideally-suited for use in outdoor and adverse conditions. Its design features rubber focus and zoom rings as well as conveniently located mode switches to enhance usability with the lens. A built-in Optical Stabilizer provides a four-stop-equivalent reduction in the appearance of camera shake, helping to enable better handheld usage and low-light shooting. The Hyper Sonic AF Motor provides fast, smooth, and quiet auto focusing for faster performance that also benefits video recording.

This lens is also compatible with the Sigma USB Dock, which allows you to use the Sigma Pro Optimization software to fine-tune certain lens settings to your own shooting needs. The ability to limit focus range, alter the AF speed, and modify the OS system is afforded through this, as well as the ability to easily update the lens' firmware.

Sports Lens Line
This lens is the first lens produced as part of Sigma's Sports line, making it ideally-suited for capturing fast-moving action with high precision. Its telephoto-length zoom range and fast maximum aperture make it especially useful for sports photography as well as wildlife, birding, and other fast-paced applications. Also benefitting these shooting scenarios is a wide range of customizable functions availed through the use of the Sigma USB Dock.
Optimized Lens Design
Well-suited to outdoor photography, a dust- and splash-proof construction enables use of this lens in adverse conditions. Joint parts, such as the mount, focus and zoom rings, and switches, are sealed to provide this resistance and improve overall durability. Parts of the lens have also been optimally designed for more comfortable use, including textured rings and well-placed switches for more efficient operation. A brass bayonet mount is also used to increase the durability at this connection point, giving more strength and rigidity between the camera and lens system.

The lens construction integrates two FLD (F Low Dispersion) glass elements and one SLD (Super Low Dispersion) glass element to help reduce color aberrations and sagittal coma flare to improve overall image quality. Lens elements also feature a Super Multi-Layer Coating to reduce flare and ghosting, which helps to improve image contrast and color fidelity throughout the zoom range.
USB Dock Compatible
This lens is compatible with the Sigma USB Dock for fine-tuning and personalizing certain functions of the lens to fit your personal shooting style. A focus limiter can be set to constrain your lens' focusing distances to suit the distances at which you are shooting. Additionally, this lens features an inner focusing and zooming configuration so the physical length of your lens does not change during use; which greatly benefits the use of certain filters such as a polarizer.

The USB Dock also allows you to customize the speed at which the autofocus system performs, how active the Optical Stabilizer system is during shooting, and allows you to easily update the lens' firmware.
Optical Stabilizer
The built-in OS (Optical Stabilizer) system enables a reduction in the appearance of camera shake up to the equivalent of four stops, resulting in a long lens that can easily be used handheld and low-light conditions. The OS system is divided into two modes; one for general shooting applications, and one that is better suited for panning shots of moving subjects. The OS system can be further adjusted to suit your needs through the use of the USB Dock.
Hyper Sonic AF Motor
The HSM (Hyper Sonic Motor) provides fast, quiet, and smooth auto focusing that is well-suited for use with video applications. This AF motor can also be manually overridden at any time by rotating the focusing ring, giving you the ability to fine-tune image sharpness through manual focusing.

    Sigma 120-300mm f/2.8 reviews

    120-300mm f/2.8 DG OS HSM Lens for Canon is rated 4.3 out of 5 by 20.
    Rated 4 out of 5 by from Sigma 120-300 Zoom Lens is outstanding when used one stop down from wide open. There is a tremendous increase in sharpness and contrast going one stop down.I have mixed feelings about the lens, but am satisfied, since I use it primarily for college football during daylight. It is not as fast focusing as the Canon 300 f2.8 I that I have. Not nearly as sharp wide open, but has the zoom range to make it very useful. I have used it with the Canon III 1.4 extender and have been amazed at the results. At f5.6 (one stop down) It is really sharp at 300mm. Note: The loss of sharpness and contrast is not nearly as much when using less than 300mm (120-200).

    Rated 5 out of 5 by from This is one awesome lens! I have that lens almost for a month now. My previous lens was Nikon 300 mm F2.8 G VRII. What can I say May be not as sharp as my predecessor and as fast but taking the fact that this is such versatile glass with such high standard of a build quality and zoom capability made me very happy. It works well with converters and as is on it's own. It has focus management capability which I haven't had a chance to use yet. I would buy this lens again. Great glass, great travel companion, saves a lot on buying other lenses and it's a such pleasure to hold it in your hands.Thanks Sigma

    Rated 5 out of 5 by from A More Affordable Sports Lens I needed a fast lens beyond 200mm for sports action at night and indoors and the Sigma 120-300mm f/2.8 Sport fit my requirements better than the much more expensive options. I had rented this lens and others before making my decision and I found that I loved its versatility and that I could live with some of the areas where it is not quite as strong as its competition. The biggest complaint that I've read on this lens is its focusing speed as compared to the Canon 300mm. It does not focus as quickly as that lens, it is true, but the only time I find it is an issue is if you are making major changes in focus distance. For example if you quickly switch from focusing on the QB to a receiver downfield, you will notice the speed difference, but for most plays, if you are in the same neighborhood, changing focus from the QB to the running back, the difference is not all that important, the Sigma is plenty snappy. I find myself using this lens indoors more than my new Canon 70-200mm f/2.8 lens, the extra zoom range is a welcome addition. The Sigma plays well with the Canon 1.4x Extender, but I've found it a little finicky with the 2.0x Extender, having a good microadjustment for the extender-lens combination makes a big difference.

    Rated 4 out of 5 by from Excellent Lens! 4.5 Rating This lens is a beast. I have a Canon 300 that I absolutely love, but as a single shooter following the ball at a baseball or fast pitch softball game, the 300mm is too much for a good part of the time. The 120-300 range is great. Used it with a 1Dx and 7Dm2. Used with a canon 1.4iii as well. Great range. Compared to the canon 300 in side by side, the image is just a touch darker. Can tell the difference looking through eyepiece. Not significant though. The focus during day games was spot on and fast. After sun down and under average baseball field lighting, it seemed to slow slightly and hunt more. During day, single AF pt, 0 issues locking on batter. After sun down, from exact same spot both at 300mm, it wanted to grab the crowd fairly often. Need to play with the focus setting in camera and lens to dial in maybe. I'm thinking of it as Canon 300 being AWESOME and Sigma 120-300 being EXCELLENT. For the zoom range I get with the Sigma and the price difference, the Sigma wins. I'll probably sell the Canon.

    Rated 5 out of 5 by from Excellent lens for video (yes!) I've seen this marketed and mostly used as a photo lens. And yes, I'm sure it's great for that. But I'm using it strictly for video with a Blackmagic URSA Mini 4.6k EF mount. Obviously, you must use rods and a universal lens support if you're going to try this. And yes, it's very heavy: not your shoulder mount setup. But I shoot almost everything on a tripod anyway. I have a Canon 70-200, which is excellent, but I was looking for a slightly better reach for the wildlife shots I make all the time. So for my specific uses, I have found this lens to be excellent.

    Rated 5 out of 5 by from No better sports telephoto lens for the price! As a Canon user, I strongly contemplated the Canon 300mm f/2.8. While YouTube reviews gave great remarks about the Sigma 120-300 lens for the features and great price, but they all seemed reluctant to make this as a first choice. As a professional photographer, I have had great experiences using Sigma lenses. However saving thousands of dollars over prime 300 or 400 f/2.8, I decided to get this Sigma lens, and so glad I did. First thing I did, after unpacking, was to plug the lens onto the Sigma USB Dock to change the focus speed to fast. I chose not to adjust the micro-focus via the firmware as this would certainly create a focus issue when using this lens on another camera body. (Adjusting the micro-focus lens firmware is unique ONLY for one camera.) I decided to individually micro-focus for each camera body from the camera menu. I think a common mistake photographers make is to assume a new lens (out of the box) is focus ready. They are not! And only leads to reviewers claiming soft focusing. And this one was no exception, though very close to being dead-on. I independently micro-focused the 120-300 on my Canon 5Diii and Canon 70D for both wide and telephoto extremes for a perfect focus using f/2.8. The main advantage of using my APS-C 70D camera using the Sigma 120-300 lens was to get the benefit of the X1.6 crop factor or equivalent extra zoom from 192-480mm @ f/3.2. Remember to calculate the f/stop for the crop factor of X1.6. This gives me a near 500mm and better than a 500mm prime @ f/4.0, plus thousands $$$ less! Now add the Sigma X1.4 or 2X teleconverter, which I have, and this Sigma lens becomes a super telephoto with a loss of 1 and 2 stops respectively. I had credentials to shoot the 2015 Armed Forces Bowl, and I had no issues of any slow auto-focusing and the images were razor sharp. In fact, focus tracked perfectly frame-to-frame as players ran towards me using burst mode on my 70D, and even on my 5Diii. Another supper advantage is that when the play got closer to me, all I had to do was to zoom back to 120mm without changing lenses and missing the shot. I use my full frame Canon 5Diii as my second camera using a Sigma 70-200 f/2.8. I will, however, mention that this is a heavy zoom lens, though I can hand hold for a short while, but for long events, such as sports, a monopod is highly recommended. If attached to a tripod, this lens also makes for a great portraits, though my primary purpose for this lens is for action sports. I am totally sold on this Sigma 120-300 f/2.8, and I can hardly wait for my next sporting event.

    Rated 5 out of 5 by from Sigma hits a home run I previously wrote a very positive review of the older OS version of this lens, which I ended up selling in order to purchase this new Sport version. Boy am I glad I did.To start with, the finish and feel of the lens is fantastic. The focus and zoom rings are smooth with just the right amount of resistance. The newly designed lens hood is of much higher quality than the older plastic one, and uses both a bayonet and locking screw mechanism to attach. It also has a very nice rubberized ring on the front of the hood to absorb minor bumps. The tripod collar turns relatively smoothly and is removable (I find a small amount of silicone spray on a cloth, then wiped on the inside of the collar helps make it turn smoother). One thing I miss though is that the older tripod collar had a beveled bottom that bolted directly onto any Arca Swiss style tripod head. Unfortunately this new one is cut square, and I will be enlisting a machinist friend of mine to bevel cut the new collar for me at some point so it works like the older one.I have read online that optically this new version is the same as its predecessor, but I find it to be better overall (perhaps newer coatings?). This is especially the case wide open, and with the Canon 1.4x and 2x model II converters. Comparing images made with the Canon 300 2.8 IS I can see more of an obvious difference with the older 120-300 over the new one. The Sport lens still is not as sharp as the Canon, but it's still REALLY sharp, all the way through the zoom range (I mentioned in my other review the Canon 300 2.8 IS is the sharpest lens I've ever used). Performance of the 120-300 Sport with the Canon 1.4x II is so good in fact, that unless I need the 2.8 aperture or 120 range the converter is pretty much permanently attached (so if you don't have the $$$$$ for the new Canon 200-400 this is a REALLY GOOD alternative in my book). You do lose some optical quality with the converters, but the performance is on par with the Canon lens + Canon converter in my opinion. Vignetting wide open is minimal, and pretty much gone by f5.6. Chromatic aberration and distortion are also almost nonexistent.This new version is said to have weather sealing for use in extreme environments. On the first day I used the new lens it actually rained, so I took the chance and left the rain cover off just to test it. It was not a soaking rain, but it did get pretty wet and so far so good.It took about three weeks after the lens became available for Sigma to release the USB dock. For the price it is worth every penny, and for one reason alone. The lens has two custom presets that you can program with different options like setting the range of the focus limiter, or the autofocus speed. The latter is what you want the dock for. Setting the lens for what the software calls Motor's drive speed priority actually makes the autofocus faster! So fast that it is hard to tell the difference between the Canon 300 2.8 IS and the Sigma. Not only is it fast but it is also incredibly accurate at that setting. It makes me wonder why Sigma would make the default setting slower in the first place. It also makes me wonder why, for the price of the lens, and the price of the dock, that the dock isn't included with the lens. The dock also lets you update the lens' firmware when a new version is released, and micro adjust the lens' focus (which I haven't played with since so far the adjustment control in the Canon bodies is sufficient enough).The lens ships with a standard black nylon case and straps similar to the old one, but I wish Sigma had updated the case and made it a little longer so you could fit a camera body attached inside. An outside pocket for holding teleconverters, the USB dock and other miscellaneous stuff would have been a nice touch too.One other thing I would mention is that, like the older version, at 300mm the Sigma doesn't magnify quite as much as the Canon 300 2.8 IS. If I had to guess it would be closer to 280mm than 300mm, but it's something I'm willing to put up with for the convenience of having the added zoom range.What else can I say other than this lens is definitely a keeper, and a truly first-class professional optic on par with others in Sigma's new Global Vision line. I'm not ready just yet to sell off the Canon 300 2.8 IS, but I can say that since getting the new Sigma the Canon lens has been living in its case.

    Rated 3 out of 5 by from Beautiful lens, but just not sharp. I really wanted to love this lens with its 2.8 aperture, beautiful finish and fantastic zoom range. I thought it would be perfect with the new Canon 7Dmll. But, it just isn't sharp. I tried two different copies, updated the lens firmware with the USB dock, and tried using the camera's micro adjustments. I just couldn't get it to sharpen. The problem was the same on both my Canon 7D and 5Dmlll. The camera microadjustment (-18) helped somewhat but just couldn't get it as sharp as my 300 f/4 or 300 f/2.8.
