I'm starting to re-ignite my interest in photography after not doing much with it for the last several years. I was mostly into macro photography but not sure if I want to necessarily pick up that route again. so I've been thinking of getting some new gear would add that little spark to heat things up. I've been eyeing the Olympus OM-D ever since a friend showed me his a few weeks ago with a Lumix 20mm 1.7 lens. it felt really solid, and was nice and small, and I loved the low light capability. it just seemed like a sweet little set-up. My current set-up is a Canon 40D, a first gen Canon EF 24-105 3.5-4.5, and a Tamron SP 90 2.8 macro. I also don't have any P&S camera except my phone. But I find lugging my 40D around is literally a pain. So i'm thinking of selling what I have now to help pay for the OM-D. Is this a good idea? I like the idea of having a smaller but nice camera that I can use interchangable lenses from what looks like a few different manufacturers. I even noticed thinkcooper using older canon FD lenses on his OM-D! so should I "upgrade"? is it an "upgrade"?
