There are many discussion threads about the Nikon 200-500, 70-300 or SigTam 100-400, 150-600. But there is hardly any talk about the Sigma 120-300 f/2.8. This lens offers an equivalent of 180-450 f/4 for DX -- up to 630 f/5.6 with 1.4x teleconverter -- similar to the latest and greatest Nikon tele lens when used with FX.
A recent thread (
D500 & "playing with light" FX style) motivates the usefulness of large apertures in a tele lens.
What do you think about a 120-300 f/2.8 for the D500?
I’m a little late to the party, but I can’t help giving my 2 cents about this lens. For examples, a number sports photos in my dPreview gallery, have been taken with my 120-300 2.8 Sport (latest model). Also on my Flickr website, all of my lacrosse pictures, have been taken with the Sigma and the D500. When I first got it, I was somewhat of a novice shooting sports, so I appreciated its ability to zoom. But at this point shooting sports, the zoom is no longer as important as it once was. I use 300mm a very good percentage of the time. So like Kris in Ct, said, I don’t really have a need for a zoom. But I keep the Sigma, because I still find it to be a great lens. It’s a sharp lens. It Auto focuses pretty fast, keeping a player running towards you in focus...with the D500. I’ve also used it with the D810 where my keeper rate with that camera was lower. With both cameras, however, the lens performed admirably. Minuses: it’s heavy. 71/2 lbs. I need to use a monopod with it, when shooting sports. When rotating the rig from horizontal to vertical, my lens in its tripod foot is not smooth. Using its VR (called OS) is noticeable when it cuts in. It isn’t as smooth as Nikon’s. Fortunately, I shoot at shutter speeds that doesn’t require stabilization. Positives: there several settings for both AF and Stabilzation. With the Sigma docking station, you can fine tune focus several focal lengths. It takes time...a lot of time. However it’s better than Nikon’s one focal length tune. Both it’s focusing ring and zoom have a smooth action. However the ring zooms in opposite direction of Nikon lenses. Not a big deal once you get used to it. It’s a very reliable performer. Is Nikon 300 2.8 prime sharper than the Sigma 120-300 2.8? Never used the Nikon ( I should rent it for comparison), but most primes are sharper than most zooms. But the last time I checked prices between the two lenses, the Nikon was about $1200 more than the Sigma. You have to decide whether that price difference is worth there difference in image quality. Kris feels it is. I’m not sure.
