Having finally gotten my hands on the Sony FE 400-800mm f/6.3-8 G OSS, it’s not the monster lens I envisioned. And that’s no bad thing. In fact it’s not much bigger, nor heavier, than the Sony FE 200-600mm f/5.6-6.3 G OSS. And while it’s bigger and heavier than the Canon RF 200-800mm f/6.3-9 IS USM, it has an internal zoom – so it’s quite a bit shorter when the Canon is maxed out at the telephoto end.
I tried the 400-800mm on the Sony A7R V at The Photography & Video Show in London, England, and was impressed with the combination’s AF speed.
