Sony just launched their NEW 400-800mm lens and I have a complete review ready to go! Sony offered me use of a pre-production model and I was happy to put it through it’s paces. 

This is a COMPLETE review and we’ll look at everything: build and features, size, weight, sharpness, AF speed, teleconverters, rendering, handling, close focus, stabilization, the zoom range, how it compares to the 200-600, and of course, we’ll talk about how that F/8 aperture worked out in the field. 

Is this the ultimate wildlife lens? Click below to find out!
