Summary: This is a quality lens that works perfect with my Nikon D7100.. Pictures are sharp and show good contrast Autofocus works quite fast and is accurate. I recommend the purchase of a Sigma 1.4 telextender and you will have a powerful duo at your beck and call. Happy shooting.
Summary: I purchased this lens to complement my Tokina 12-24mm f/4 and Sigma 17-50mm f/2.8 OS for my Nikon D7100. The 50-150mm is super sharp even at f/2.8 and all focal lengths. Focus is fast and bokeh is very nice - Very pleased!
Summary: I have been waiting for this lens for a year. Finally I bought it one week ago. Let me tell you it is a Sharp lens! Tamron and Sigma are catching up with Nikon and Canon. This is actually a pro lens to DX shooters with optical stabilization. The photos I've taken are sharp wide open at all focal lengths. Bokeh is creamy as my Nikon 35mm F1.8 .
Summary: After a lot of review reading on the internet and bouncing back and forth between breaking the bank on a Canon 70-200 2.8 Mk2... I decided to go with the 50-150 for the following reasons. 1. On crop it provides similar field of view as 70-200 does on full frame. This removes some of the awkward focal length that you get when using a 70-200 lens on crop. I really enjoy being able to use the 50mm wide end, although can still feel crowded at times it provides versatility.
