Excerpt: I love this lens that I have been using for the last 2 years. In a good light environment, it functions very well. I have done a lot of nature photography and they are just perfect. But the flaw is inside in low light situation, it become very quickly a bit frustrating.
Excerpt: Really nice and clear photographs, it does focus somewhat slow but not too bad. The range is great, personally would prefer something like a 200 but that is just me. Where I was most happy with this lens was at weddings, I was really happy with it's performance especially outdoor weddings, since...
Excerpt: Autofocus is okay but not great, may struggle in low light. If you shoot action photos, this is not for you. The contrast and rendition is good. The bokeh is buttery. In my opinion, this lens is not worth the amount placed on it. the sharpness is not anywhere near zeiss.
Excerpt: Fairly fast lens with good range for travel photos other than landscapes 16-50 for those. Autofocus fast enough, and works well in low light situations. Can handhold without blur at slow shutter speeds. Somewhat heavy.
Pros: Durable, Easily Interchangeable, Fast / accurate auto-focus, Nice sharpness, Strong Construction
