Re: Focal length 35mm equivalent, but not F-stop?

That would cause even more confusion. Equivalent f is needed only to compare dof. But it doesn't change for exposure calculations. If equivalent f would be widely used - I'm sure, that lots of people would think, that lens is faster that it actually is.
