What makes a lens long?
6 months ago

I'm quite new to the world of exchangeable lenses, having had only compact cameras until now. I got myself a gm1 and then started to ask myself questions about the size of lenses...

What makes a lens long?

It's not the speed. I have see fast and relatively compact lenses. It's not the focal length. There are lenses out there with both very wide and narrow angles. So what is it?

Now that I think of it I haven't seen any flat (pancake) narrow angle lenses. Would that be impossible? Or perhaps just very expensive?
