Re: Are any lenses marked with physical aperture and FOV at distance?

So the two things that affect DOF when shooting are aperture diameter (not the same as f-stop) and distance.

The problem is that lenses are not marked with physical aperture and FOV at a fixed distance; they are marked with focal length and f-stop. If you were carrying both cameras and wanted to take a comparable photo with each, the easy way is to use the crop factor times the f-stop and focal length to choose lenses and apertures.

Well, I'm not really sure why I'd want to do that, but even granted that's an easy way to do so, I think there's still value in understanding what's really going on. I see little advantage to passing on misinformation.
