Summary: so far really liking this lens - it replaced both our 28mm-50mm and our 50mm-250mm I decided on it because we were going on vacation and I did not want to be swapping lenses all the time, making taking opportune photos so much nicer, no missing shots due to switching lenses This was recommended by a friend who has been using it for quite some time and really had good luck with it.
Excerpt: I really love the range of this lens. It is very sharp. The only reasons I didn't give it 5 stars is that it is not great in low light. Also when shooting downward, lens creep is an issue. For my purposes it is an excellent lens. I use it outside in daylight and indoors with a speedlite.<br />I purchased it used, but it looks and works like brand new! I love dealing with Adorama!
Excerpt: If you want to carry just one lens, this it. Especially good for travel photography. It is small and light enough not to be a bother. <br /><br />The auto focus can be a little slow, especially when there is not enough contrast. 95% of the time, it works well. When the camera hangs down, the barrel of the lens extends fully, unless you lock it first.<br /><br />Overall, very happy with this lens.
Excerpt: It's not a fast lens<br />It's not an L lens<br />It's nit the sharpest lens at either extreme.<br /><br />It IS an easy multipurpose lens.<br />If you understand the limitations and want to travel light or not mess with changing lenses and risk missing a memorable moment (kids play/activity)<br />It is great. Does it have it's limitations yes, but you should know that when you buy it.
Summary: Quality lens at a good price point. Use one at work liked it so much bought one for personal use for my wife. Can carry one lens for multiple situations from landscape to close up. No problems with it yet, good lens for photography enthusiasts.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight, Strong Construction
Excerpt: This is my first non-Canon lens and I am pleased with its performance. Build quality is good, weight is just right, and above all, I get super photo results. This will be my go-to walk about lens for quite a while.
