Excerpt: i use this product for sports and some closeup nature shots. i use it with a canon t3i. the zoom is really awesome but with the extreme zoom comes an aperture thats not constant, meaning the aperture will get small as it zooms in more. so the lens is not that fast with a fastest at f4.
Pros: Durable, Easily Interchangeable, Fast / accurate auto-focus, Rugged, Zoom Range
Cons: Heavy, Non-Constant Aperture, Poor in Low Light
Tamron 70-300mm f/4-5.6 Di VC USD SP AF review by jwphoto
28 December 2014
Summary: A surprising good lens, did read many reviews in order to choose between nikon 70-300 and this one , in the end the Tamron was best in most of the reviews. So bought one. (nikon was $ 713 that's $ 300 more !
Pros: Sharp, light, accurate autofocus , inexpensive
Excerpt: This Tamrom lens is really a good option.Inspite some minor issues, the image quality and the price you pay for it makes this lens one of the best options on the market.What minor issues?? The image stabilizer button is somewhat protruding, and accidentally can be changed without you notice it.
Pros: Consistent Output, Fast / accurate auto-focus, Price
