Excerpt: This lens works exactly as I expected it to. I primarily use it for photographing food, but it's amazing as a telephoto zoom lens as well and can capture objects FAR away with great clarity and detail.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Lightweight
Excerpt: Within 24 hours of using this lense has been the best thing ever! My backyard is filled with ton of birds including Orioles and it was difficult with my standard lense because they were so far away but now with the new lense I can get up close photos.
Pros: Consistent Output, Durable, Easily Interchangeable, Fast / accurate auto-focus, Nice Bokeh, Rugged, Strong Construction
Excerpt: I mostly use this product for aerial photography. Obviously, it's huge zoom capacity makes it great for getting shots of things on the ground, and/or far away while in the air. The only down side is that the lens physically telescopes a sizable distance.
