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!!! :lol:


Yes indeed.
I shoot my Nikon 200-500 f5.6 at f5.6-8. My 400mm f2.8 I use at no smaller than f4 unless I am already at 1/8000 already, so I need to stop down to get correct exposure.
