I've been exploring bigger better lenses lately, which means my arsenal has been gaining Four Thirds glass. These are workable on m4/3, but I'm wondering now that as long as I've got these big Oly HG lenses, maybe I should add a DSLR body for the times when it's useful to have one. I'm thinking continuous AF for motorsports and other sports, basically. Since that's not a strong point for m4/3 yet, it might be a nice bridge for when those photo opportunities are happening. So, does it make sense to buy a 4/3 DSLR now, and which one is a sane choice in price/performance tradeoff?
