Re: WOW - been away a long time, came back to sell my 150.
I haven't been here for a long time either but I have gone mainly micro 4/3 and sold all my canon and Nikon gear, I didn't use it since it was so big and heavy. I use a 150/f2, 7-14 f4 and a 50-200 zoom with adapters but for the focal lengths I use most I have bought micro 4/3 lenses.
Getting a bright viewfinder through such a small aperture must be expensive/limiting and I have no problem with the electronic one. I sold my E3.
Olympus E-P2, Panasonic GH1, several lenses
Canon 7D, 1Ds Mk2 loads of lenses
Nikon D3x, D300 several AI lenses, some AF lenses
Leica M8.2, Leica M9 enough lenses
