The Tamron 70-300mm f/4.5-6.3 Di III RXD should be a hot seller, but it’s kind of surprising the Sony FE 70-300mm f/4.5-5.6 G OSS is a little bit smaller than Tamron’s more modern design. The Tamron is still a little lighter though at 545g compared to the Sony at 854g and the Tamron is half the price of the old Sony.
