Excerpt: Nice lens, easy to use and sharp, but not much more than the Sigma 18-250 mm f/3.5-6.3 I already own and use on a Canon 60D. I bought if for the larger aperture anticipating better IQ but found that a Fujifilm X30 28-112 mm with an f/2-2.8 lens that I bought later for travel use handled the larger aperture situations just as well in my pixel-peeping tests using RAW+JPEG images and provided JPEG results SOOC extremely well.
Pros: Durable, Fast / accurate auto-focus, Smooth To Use
Excerpt: I purchased for indoor and outdoor use. F2.8 was the key, although the focal length was somewhat too short. I wish it could go up to 70 or 80mm. 50 mmm @ F2.8 was marginally better than my 18-200mm Nikor. It is also pretty heavy lens. 17mm actually makes a difference, which is wider than my 18-200mm. It is a sharp lens, but the corners are not sharp especially at 17mm @ F2.8. This was one of the major reasons I returned this lens.
Summary: Does not work below 60F. Gives a lens error on my 70d, stops auto-focusing and won't release the shutter. Otherwise, it a fantastic lens. Very sharp and the OS works great. Update after 1 month: I'm returning it to see if I just had a bad copy. I found one other person with the issue of this lens not working in cold weather so it doesn't seem common. I took it out today on a 60 degree sunny day and it failed to communicate with the camera.
Excerpt: It's a very useful lens for portraits, group shots and some landscape. But I have some problem with focusing. I think the auto focus motor is not very compatible with Nikon D7000. you should be really try hard to get tack sharp shots.
Summary: The lens gives me more capabilities because it can hold F2.8 at any zoom; both for low light and creating a shallow depth (making subjects pop by making the background out of focus). I like the lens but don't love it. The AF searches some times. The images are good but not great (might be my inexperience). I recommend it if your on a budget. The constant F2.8 is nice and allows me to take shots I couldn't with my kit lens.
Excerpt: First of all, this lens is HEAVY! Add that to 7d and it is quite heavy. Now, that being said, I researched which lens to buy for a long time before purchasing this lens. I'd have to say everything I read by users was true. 1)It tends to produce warmer color indoors for sure. 2)It's not as as good for low light/fast action, which is why I bought it in the first place. I shot an outdoor wedding and reception held indoors with low light.
Summary: I bought this as part of a 2-lens solution to replace my sony 18-135. The sony lens didn't have enough magnification to get close enough at my kids school concert events and some sporting events. I really need 250-300 on the long end of my zoom to meet those needs. Also the sony didn't produce enough bokeh (background blur) and was fairly hit and miss for me in terms of getting sharp shots for indoor natural lighting or low lighting. So, on the shorter end of 18-??
