Much better than I could imagine. I use sigma 17-50 on my D 7500 for the past two months and to my surprise it beats the Nikon 16-80 which I own for one week and return (noisy focus).This is my first sigma lens.It is little heavy but very sharp,fast focus and very quiet.Produces good colors and I love it.As far as durability-time will show.

I just got these lens, and pretty much like you can see from reviews on youtube, it doesnt quite get to 50mm. It's something about focus breathing, so it's not like Sigma is "cheating" you or anything, you can look it up on Google. Compared it with another 50mm lens, and the view angle is larger. Camera on tripod and static subject. So you don't quite get the promised 50mm, more like 42-43mm eyeballing it, if your subject is closer then infinity. Still a fantastic lens, super cheap, fast and ...

Just a note of caution for potential buyers. On my Nikon D7100, and on a D7000 & D3200 i tested it so far exhibits an OS bug : OS is constantly activated. The OS switch has no effect (function). This comes with a series of side-effects : Battery drain, possible tripod use issues, image playback scroll is hindered, image preview auto-off is hindered, possible sharpness issues from unwanted stabilization with high shutter speeds, etc Also HSM is not full HSM: you have to switch to M in order to ...

This lens was recommended to me by more than one review and person so I've always wondered about it. I've tried most of the various Nikon kit lenses to death and I figured it was time for a fast zoom, and the Sigma does not disappoint. First and foremost the lens is very sharp. It needs -6 adjustment on my D7000, don't know who to blame the camera or the lens. Anyway once adjusted I try to shoot at f/4, which is noticeably sharper than 2.8. Most tests tell you 2.8 is not that sharp but ...

I bought this lens recently to replace my nikon primes (yes, indeed) and to replace my 16-85 with just one lens to carry around.  I wanted to avoid changing lenses, and carry only one lens for holidays and family events, while still being able to shoot in low(er) light indoor and at local gigs. Sacrifices I made with this move are limited, 2.8 vs 1.8 when using the primes, 1mm wide angle but quite a lot on the tele end compared to the 16-85.  What I got in return was 1 lens instead of three, ...

I was excited to try this lens.  Pics that others had taken with it looked really good to me.  The lens would not focus though on my D7000, at least not with the viewfinder. It seemed to focus okay using live view, but it would not using the viewfinder.  Really took the wind out of my sails.  Live view is too slow to be practical for me in a lot of situations.  I needed it to focus with the viewfinder, but it was terrible.  Back-focused terribly.  Off the charts bad.  It was unusable.  Could ...

I used this lens for the first time on a road trip through Washington and Oregon with excellent results. The quality of the image is equal with the Nikon lens I have. As far as I can tell there is no vignetting at the fringes. The AF is a little slower than the Nikon but, it wasn't anything I couldn't handle. Used this lens in low light and the images came out great. For the price, I would say that this is an excellent buy and an excellent product for the amateur photographer.

Well, it's not what I expected. The build quality is nice, but the focus is loud (a stuttering grinding noise), there's shaking inside the lens, the lens hood is super loose, and lastly the zoom ring makes a screeching noise. It's no L glass build quality, but I wasn't expecting that either.

I like this lense. Lots of photographers avoid it, but video quality is great. It also gives a nice bokeh if you shoot wide open and it it is quite and fast. I use it for all my wedding videos and it is OK lense to have. No comparisson to small nikkor 35mm 1.8G thou You may wish to check some of my videos shot with this Sigma 17-50mm 2.8 http://tvc.kz/videosemka-portfolio.html
