Tamron 50-400mm f/4.5-6.3 (Sony E)
A stabilized superzoom for Sony E, the Tamron 50-400mm reaches deep into wildlife and field territory at a manageable 1,155g and a small 67mm filter thread, landing at an enthusiast-tier 73. The variable f/4.5-6.3 aperture is the catch. It suits budget-minded reach hunters who shoot in good light, but pass if you need fast-aperture telephoto performance in dim conditions.
