Tamron has been in the lens business for a long time, having established itself as a major third-party player for SLR systems going back decades. Despite that pedigree, Tamron had barely dipped its toes in the waters of mirrorless for many years before finally jumping in to the Sony E mount system in earnest two years ago with the 28-75mm f/2.8.

The one-stop slower 70-200mm f/4 G is 7 inches long and 840g. Meanwhile, the Tamron 70-180mm f/2.8 is only 5.9 inches long and just 810g.
