I'm just thinking that a longer lens would have given the same DOF and more or less same FOV, but at a further focus distance of course.
That shot of the fair ride could have been done at twice the focus distance with a 50mm at f2??
You can move back with a longer lens, trying to keep the FOV the same, but then the perspective changes and you get a different shot. And in that particular case at 50mm I think I would have been standing in the ring-toss pond behind me.
Quote: So perhaps if the user sees/composes and uses focal lengths differently between FF and APS-C, that practically they are getting the same thing?
When possible, yes, but it's not always possible to do that. And sometimes it's just not convenient. I shoot the same way with a 50mm on FF vs a 35mm on aps-c, my subjects are all usually the same distance away with both formats, especially if I'm shooting indoors. In situations like that I see the dfference quite often. In other situations, you may have a lot of leeway with distance to subject, several lenses to try, etc, and you could recreate anything as long as perspective doesn't matter to the shot.

Yes.
