Hi guys...

pls help me with the following:


1. Aperture are they EXACTLY the same size for ALL lenses? For example, F2.8 on a 17-40L is it the same aperture diamater as F2.8 on a 50/f1.4?

2. What are rangefinders? how are they better / worse than conventional SLR?

Thanks!!

this mean for fixed aperture zooms, the physical aperture actually opens up as you zoom in? cool, never knew that.
