For true sports and wildlife photographers wanting to use the Sony mirrorless system there was always one really big – glaring, really – hole in their lens ecosystem still, hast super-telephoto prime lenses for shooting sports and wildlife from a distance.
So if all the stars align just right, I think that one of the big announcements that we're going to see this year from Nikon will be the new Nikon AF-S NIKKOR 500mm f5. 6E PF ED VR that they're announcing the development of today.
I used to be one of those street photography believers: you know, the ones that always say that you need either a 28mm, 35mm or 50mm lens to create street photos. And that there is nothing else that you can possibly use whatsoever.
