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

because they don't want you to know

Multiplying focal length isn't a bad thing. A 1000MM equivalent lens can be very useful.

But do you think they want to know that aperture gets multiplied as well? All of the sudden that F2.8 lens you thought was really fast is really only F10 equivalent?

Of course not! Because people might figure out that a true F2.8 FF lens is actually a pretty good deal compared to a smaller format equivalent F10 lens. And the public would know the lenses are smaller because they do less, not because of any magic dust.

What advertise your shortcomings? It's all about marketing.
