No argument there.You just wouldn't maintain the same FOV. As far as I know, it's not possible to make the lens faster without making it larger.
Ah, good point. I was only considering on-camera flash - the only way I shoot fill flash.Regarding fill flash: I don't see the issue there. It's rather the opposite, a longer FL gives you a narrower FOV therefore you have an even greater choice of positioning your flash unit.
