They are coming. Let’s face it the F Mount has been around a long time! How many decades did it take till Nikon introduced the PF lenses and some of their long zooms? Sony is still relatively new and they are continuing to bring out new glass and cameras at a pace no other company is currently doing. It’s essentially June and Nikon hasn’t released any lenses or bodies this year. Sony has announced and shipped multiple bodies and lenses.
I understand that, but can say that
If anyone cares, here is a review of the 100-400GM lens. The MTF charts show that the lens is sharp wide open, but even better stopped down. I think that the horizontal axis is the distance from the lens centre.
(don't ask me what MTF means)
Sony does sell 400/f2.8 and 600/f4, but these cost 1.7x an A1I would be happy with a compact 600/f7.1 for $4,000 US.
Yep, 400/f2.8 and 600/f4 are too expensive for some of us. Hoping for one of the "in between" lenses or, as Doug mentioned, for Nikon to produce/release a mirrorless option for action photography.
