I think there is also a lot of 'boxed in thinking'. That is to say if you have a f2.8 lens then you need to stop down to f5.6 to get best results and likewise if you have an f4 lens then it will need to be f8 to get most out of it. Get over it. Yes old lenses may behave like this but not necessarily the truth with newer lenses. Of course this is complete BS. The Nikon 400mm f2.8 AFS is as optically good at f2.8 as at f8. There is almost no difference between any of the stops between f2.8 - f8.

I find the 500mm is producing spot on right up to f16 needless to say depth of field is a major problem with long lenses.This means good results with high ISO is a major advantagemeven in good light I wind up ISO to stop down as much as possible. Sory today not able to get Blackbird with 500mm lens and D500 I may have just set one too far!! We had bit of snow top temp + 1.4 cent and the birds were low all day on the ground feeders.

Apart from bokeh and DoF. My excuse for fast lenses of both of these. A long while ago I went on a photography 'course' The trainer asked what aperture I was using with my Nikkor 300mm f2.8, he was a bit taken aback when I told him I hadn't paid a small fortune for it to shoot at f8. Why have a fast lens then stop down except if the DoF requires it. My whole aim in photography is to separate the subject from the background. Mind you, it also helps me keep the shutter speed up... To help with my doddery hands!!!

But there is more than double the dof between f2.8 and f8 and shooting moving birds at 30-40 feet you need all the lattitiude you can get. That's why many people use f8 or smaller. Anyway...the Fuji 100-400 and teleconverter prevent me from using anything wider.

Who needs medium format when you can get this from a Fuji. Reduced for better viewing on smaller devices!
