Okay, I get that f7.1 isn’t a big deal for a mirrorless full frame camera, but for an “L” lens?
Doesn’t say “L” to me.
L also references build & IQ. If it is f5.6 @ 400mm and not much larger/heavier, I will take this over the 100-400 any day if it has the same/better IQ. The advantage is that I don't have to carry a teleconverter to get out to 500mm and am still at f7.1 instead of f8. Yes, I know I give up 60mm, but I will also have 40+mp to crop. Not a bad trade off. Combine that with better ISO performance of the new sensor and should be a net win.
