Lens physics? eg - Pana FZ200 f2.8 @ 60mm?
Sep 18, 2012

I struggled with where to post this, its a question about lens physics so here I am at Open Talk but I apologize if it should be in the Pana talk forum.


Can someone describe - feel free to dumb down - the lens physics that makes it so newsworthy that the FZ200 has a consistent max aperture from 24 to 600mm.

While I understand its a teenyweeny sensor that enables superzooms I don't understand why 1 camera can have a f2.8 all the way out vs the rest? Is there a downside to this (like the downside of a teenyweeny sensor)?

Can't anybody (Nikanon?) do this? Surely whatever it is, is reverse engineerable. Patents?

Any lens engineers our there?
