The Tamron 70-300 mm F4.5-6.3 Di III RXD (A047) is an inexpensive telephoto zoom for full-frame cameras. It shows weaknesses in the edge resolution and distortion, which are not unusual for the price range, but are surprising. However, there is no reason to criticise the workmanship and autofocus.

The very well made Tamron 4.5-6.3/70-300 mm Di III RXD should be stopped down despite the existing light weakness.

High telephoto performance at an affordable price was the focus of the Tamron 70-300mm, F4.5-6.3 Di III RXD. The lens delivers this and also scores with its compact size and low weight. This comes at the price of a missing image stabiliser and relatively low speed.
