m4/3 has been around for what, about 2 years ?
How many lenses do you really expect for a small niche system thats not even supported by the bigger 3rd parties like Sigma, Tamron etc yet, nor that has the history of brands like Canon or Nikon ???
If you want a wide range of lenses, then the Canon or Nikon mounts are the way to go
m4/3 is growing, and in time there will be plenty of options, but I'm pretty sure when the other brands started out they didn't have tons of choices either
How many lenses does Sony have compared to the time they've been in the DSLR market ?
Look at the Samsung system, how many lenses do they have ? m4/3 isn't half bad, maybe not exactly what everyone wants but they are getting there
Its not like they should of designed an entire range of lenses, with something for everyone at the same time they introduced the concept now is it ?
Suppose it didn't take off ?
The fact we've got a few nice wide angle options, some tele options, a great superzoom optimized for video, a dedicated macro, and a fast normal prime is pretty great if you ask me
I'd like to see a fast tele, f2.0 or faster, and with AF as much as anyone, but its not going to happen overnight, nor is that probably the best seller they'd have
the "average" person probably is more attracted to wide angle or tele zooms
A fast tele prime is more of a specialized tool for enthusisant, and frankly most enthusiast already have a DSLR kit and such glass, and lets face it, for portraits etc, the DSLR kit is a better tool anyways
I don't think anyone serious about portrait photography would choose m4/3 as the system they base their business around.
