Yeah, I’ve read quite a few comments like: “I sold my [Canon/Nikon/whatever] gear and bought an OM-D”. Seems to happen more often than not.
But on Andreas Manessinger’s blog I found the one of John W. Griggs, and I’m glad I did. Both are photographers who show work I really like. And John has some incredible articles as well. Should you be interested in a camera, you’ll find loads of information at his site.
Both are recommended reading.
