Is a fast 50mm equiv available? Doesn't seem to much choice in small, light primes which I prefer over heavy zooms. I only slum it with zooms if I need to change focal length faster than I can move position or change lenses.

Not much choice in standard zooms with constant fast apertures from what I can see.

Long macro lenses...you need to get a Sigma lens if you want something longer that the Oly 50mm macro IIRC.

Is there a 2x teleconvertor?
