For superteles, f-stops matter because of shutter speed, and increasingly, autofocus performance. It's a unique portion of the photography world, to be sure, but you don't have to be a pro to see real material benefit from an additional f-stop.
Sneaking through the jungle near dusk, shooting 800mm f/8 handheld on a crop body, there's not much I wouldn't do for an extra stop.
- ghaff 8y agoI probably shouldn't have drawn a distinction between full-time pros and very serious amateurs in the ultra-tele niche. And that's absolutely a fair point about autofocus especially at the highest focal lengths. But obviously 800mm lenses are already pretty niche.
