There are certain 70-300mm lenses that are simply better than others. And in our opinion, Tamron’s is incredible. In fact, we think that it’s so great that we took a look at our review done several years ago and issues an update. We previously updated it when testing it with the Nikon Z9. However, we recently used it with the Sony a9 III and fell in love with the images we were able to make with it.
