One of the most commercially successful lenses in recent years was the Tamron 28-75mm f/2.8 Di III RXD, which offered an impressive blend of performance, image quality, and portability all at a very affordable price, particularly when compared to other 24-70mm f/2.8 options. The second iteration of the lens is here, and it brings with it a range of improvements. This great video review takes a look at the lens and the kind of image quality and performance you can expect from it in the real world.
