Asking as a videographer, why do you think this is made for videographers? If anything, video lenses require better, not worse optics than photogeaphy lenses and f/8 is a non-starter. They also have fairly specific features that aren't obvious here.So is this a response to the Canon telescope? Does anyone know if it is internal/external zoom, approximate price, etc? I guess it would be a bit smaller than the 800 PF simply because it is f/8, but given that Sony has the solid 200-600, I'm surprised that they didn't try to produce a lightweight 800 similar to Nikon's PF. Then again, as arbitrage observed, it may be aimed at videographers?
It seems to me like an entry-level supertele zoom and I'm sure it'll do great. I couldn't imagine using it for video.
