I am a US military member deployed to Pakistan, and I recently sold a Canon 20D body and several L series lenses to get the Olympus OM-D with the 12-50 lens (I am amazed how small it is), the Pany 45-200 telezoom, and the Pany 25/f1.4 lens that has not arrived yet. I am hoping to add a wide angle prime like the Oly 12/f2 and perhaps the Rokinon 7.5mm/f3.5 fisheye soon as well. I've been shooting for about 35 years, having started with B&W film and darkrooms as a kid. I've since moved from that to color slide film, went back to B&W for awhile, then jumped to digital with the 20D about eight years ago. I love the freedom and flexibility digital provides, but I'd started to dislike the size and weight of my Canon kit. And, as a result, I didn't take as many places as I would have liked. The L series lenses were unquestionably nice and sharp, but weighed a ton and weren't small by any means. I just got my OM-D a few days ago, and I am amazed at how small & light it is, yet still produces amazing image quality. Some pixel peepers might find flaws in the sensor size or the inability to do some particular niche task. I think that for the far majority of photographers, something like the OM-D/m4/3rds (high IQ, yet small/light) is the wave of the future. It seems a lot of you agree!
