Excerpt: I bought this lens a couple years ago and haven't use it much but while browsing the 24-70 ranges, decided to shoot a few with my 23-75 Tamron. After this experiment, I expect to do a lot more with this lens as a walk-around on my D700.
Pros: Consistent Output, Fast / accurate auto-focus, Lightweight, Nice Bokeh
Summary: I bought this lens because I needed an f/2.8 lens to photograph in low-light conditions. I have been using it since I received the lens about a month ago and it has become my all-around lens. The lens itself feels sturdy, but its not that heavy. So far I'm delighted with the lens --which, by the way, I got new for less than $400.00. That's cheap.
Excerpt: I've had this lens a few weeks now and it hasn't come off my Nikon D7100, I love it! Its been great for people photos and nature, just a great walk-around lens. The focus is fast, even in low light. The build quality and size also seem just right. Its also good for close up photography, got some great flower shots.
Pros: Consistent Output, Fast / accurate auto-focus, Nice Bokeh, Strong Construction
Summary: Very impressed. Not quite as sharpness the 24 70 nikon I rented when stopped down but wide open I've be pressed to tell much of a difference. . Sharp and high contrast lens overall. Very minimal and in most situations nonexistent chromatic abbreviation. Have already recommended to friends with confidence and will continue to do so.
Excerpt: I purchased one 3 or 4 years ago. While visiting my daughter whom I had a couple years age give my old D200 after I purchased a new D800. I gave her my old Tamron 28-75mm f2.8 lens. And order myself a second one.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight
