ThePhoBlographer published the full review and concluded:
A 500mm lens captures photos that smaller lenses simply don’t. The Tamron 150-500mm f5-6.7 Di III VC VXD has great reach. And while heavy, it’s not too heavy to wield without a tripod, thanks to stabilization. Despite making a big zoom compact, the lens does a good job of managing distortion and aberration. The center is sharp, and the colors are great. The long focal length and close focusing capabilities can still produce some good background separation.
But, the corners are soft and, while the center is sharp, at 500mm, you’ll be using higher ISOs. The lens also lacks weather-sealing. And I found the autofocus to be good but not great. (But again, this was partially from the camera body, not the lens itself.)
For about $1,400, the Tamron 150-500mm f5-6.7 Di III VC VXD does an impressive job of bringing distant subjects in close. While not perfect, I think wildlife photographers and hobbyist sports photographers will really love this lens — I know I did. I’m giving the lens four out of five stars.
