p.1 #4 · Whale watching lens suggestion for Sony E Mount
To a certain extent focal length will depend on boat size and how close they are allowed to get. My past experience with a Nat Geo trip called for at least a 100-400 lens.

Depends on what the regulations are in that area regarding how close/far boats are allowed to be from the whales. At least 70-200mm and a fast lens as the whales & the boat will be moving.

I went once out of Morro Bay,
Central California, with a 200-600. A smaller boat and not calm. I think the 100-400 types suggested sound good. While the boats aren't supposed to get too close, the whales are moving and can approach the boats. The 200-600 took some wrestling to handle while staying in a safe or steady position.
