I bought this lens to use with a new Nikon D7200. As with all third-party lenses, you take the risk of compatibility issues and I seem to have run into a small one here. However, it is not really a deal breaker.
The lens itself is nice and sharp. The AF is decently fast and the fast f2.8 aperture is welcome when shooting indoors. Optically, I am very happy with this lens. The OS (optical stabilizer) seems to be working fine.
When using the lens, you have to be aware that this is a slightly older model, and the focus ring rotates during autofocus. In addition, you have to move the switch to manual focus if you want to manual focus. You cannot override the AF by just turning the focus ring. This also results in a somewhat irritating situation if you happen to have your fingers on the focus ring during autofocus. Since the ring turns, you'll hear a whine when it fights your fingers. So, try to keep your fingers off the focus ring when using AF.
Next, the image metadata from my Nikon D7200 does not correctly note if the image stabilization is on or off. This is a minor thing, but is one of those compatibility things you should be aware of.
I've saved the biggest compatibility issue for last. The OS system of the lens stays awake for a full minute, keeping the camera from going into standby for a whole minute (I have mine set for 6 seconds). I have yet to shoot through a whole day using the lens so I cannot provide an accurate number regarding how much this affects battery life. However, from other sources I have read, this can reduce effective battery life by 10-20%. My workaround is to turn off the camera when I have completed a sequence of shots. I have read that a Sigma service center can update the firmware on the lens to deal with this issue. I have not tried that yet.
My overall thoughts?
This lens is great optically. It is also much more affordable than the comparable
Nikon AF-S DX NIKKOR 17-55mm f/2.8G IF-ED Zoom Lens with Auto Focus for Nikon DSLR Cameras
, which costs over twice as much. The compatibility issues are relatively minor, and if you carry a spare battery or two with you on long shoots, will not result in major issues. I am happy with the lens because it gives me good optical quality at an affordable price. I'm removing a star because of the compatibility issues, but that is not going to stop me from using the lens.

The nice thing about modern DSLR's is that they come with a kit lens that covers most of the focal lengths you would typically need. The bad thing is that these kit lenses aren't very good unless you shoot jpeg's in Auto.2016年10月18日 在美国审核
My trusty Sony Rx100 m2 had fallen into disuse, so I opted to sell it back to Amazon recently. I think it makes more sense to focus on a single camera when you want to improve your fundamentals, and at any rate, my S7 is light-years ahead of my old iPhone in terms of the camera, so I was reaching for the RX100 less and less. The plan was to acquire a new lens for my Nikon D5500 that would be versatile enough for portraits of my daughter and landscapes as well as walking around Chicago or Madison, and I was considering a few. The most important feature was a constant aperture, followed by image stabilization.
Nikon's own 16-80mm is prohibitively expensive for someone who isn't a professional photographer. I suppose I could have bitten the bullet, but all of the reviews said the same thing: decent image quality, but not a good value proposition. If I'm gonna spend $1000, it had better be a GREAT value.
Tamron offers a 17-50mm f/2.8, but again, the reviews put me off. Everyone seemed to prefer the older model for IQ; not what you want to hear for a $500 lens.
So I looked into the Sigma 17-50mm. In terms of IQ, it beats both the Nikkor 16-80 and the Tamron. It's just over 1/3 of the price of the Nikkor, and at the time I was shopping it was about $100 less than the Tamron. Every review singled out its stellar build quality, and IQ was very good to great at all focal lengths.
When I got the package I was surprised at how heavy it was. This lens is HEAVY. It's a bit unbalanced on my D5500, but I expect to upgrade to a more advanced DX body in the next year or so, and I imagine a larger body will solve that issue.
In terms of IQ, the only lens I have that can beat it is my Nikkor 50mm AF-S F/1.8. If I owned a full-frame camera I would probably never use another lens. That being said, a 50mm FX lens (75mm equivalent on a DX body) is not very versatile. Ditto my Nikkor AF-S 35mm F/1.8; phenomenal IQ, but not all that versatile on vacation or a day trip.
I would highly recommend this lens for anyone who wants an upgrade over their kit lens. It performs well at all focal lengths, its fixed f/2.8 aperture makes it extremely versatile, and in terms of value for your money, I don't think you can find a better option.
