hi there, i have a small m4/3 setup, i have the gf1 with the 20mm and a nissin di466 flash to go with it. i was thinking of adding a 14-45 zoom to my set up. while the pancake 20mm is great, there are times when using a zoom lens is more appropriate than a prime. i guess what's holding me back is that i'm worried that the system isn't here to stay, and investing more in it would not be a wise move. m4/3 lenses are expensive. since sony is able to put apsc size sensor in a very compact nex, i cant help but think that panasonic and olympus would follow and start putting bigger sensors in compact bodies and just drop the m4/3 system. there are also rumors about canon releasing their own MILC. do anyone here think this is likely? or am i just worrying about nothing?
