The Tamron AF 70-300mm f/4-5.6 Di VC USD performed fairly well in our full format test but it is a more desirable lens on an APS-C DSLR. The resolution figures are very high in the scope and that's, at least mostly, across the image frame.

The Tamron SP AF 70-300mm F/4-5,6 Di VC USD (for Canon Digital SLR) Lens is carefully constructed with 17 elements in 12 different groups to give you perfect pictures. The size and weight is not much, which makes it convenient to carry around. Overall, it is a good buy at the price.

Tl;dr: low aberration is a boon, distortion is well controlled, Tamron priced it well The full review: Tamron made this lens to fit well in an area that is kind of empty: mid-range telephoto lenses under $1k, and the features that it offers is excellent.

Have had this lens about a month and overall I'm quite satisfied. Images are sharp as a tack through all zoom ranges (may drop off slightly at max but not objectionable). Image stabilization is excellent and is better than I expected. Overall operation is smooth and quiet.

I was very excited to receive the lens but was very disappointed, really. I was going to shoot a football game and thought this will be a win. I did not take my canon len with me. Anything in the range of over 100 was not focused. I thought it was me. I tried it with tripod and the issue the same.

Unlike the somewhat basic affair that is the Tamron AF 70-300mm Macro , the new Tamron SP 70-300mm f/4-5.6 Di VC USD has all the latest bells and whistles, or at least their high-tech, optical equivalents.

The Tamron 70-300mm f/4-5.6 SP DI VC USD features both Low Dispersion (LD) and Extra Low Dispersion (XLD) lens elements to help correct chromatic aberration and is also fitted with an Ultrasonic Silent Drive (USD) motor, as well as Tamron's Vibration Compensation (VC) mechanism to reduce the effects...

An absolute dream of a lens! Coupled to my Sony A77ii it is giving me the finest results I have ever had in over 60 years of photography, it is an amazing piece of equipment.

This lense is a lovely accompaniment to my other glass. Takes much clearer pictures than the 250mm Canon lense, and has further zoom. Great buy for the price.

This is a highly recommended lens for a TELEPHOTO user under a budget .I really like its results and its VR is quite impressive. TAMRON has built a QUALITY PRODUCT !!!
