I wonder if you guys could help me sort out some thoughts I've been having. I've had a D5000 for a few years now, and love it, but find myself not wanting to take it places because it's big and bulky and heavy, so ended up trying to rely on my S90 compact. I recently got the GX1, and it's wonderful. In my own image comparisons, ISO noise is about equal with the D5000 at 3200 and 6400. It's also so much more fun to carry about and actually take photos with. I love using natural light, and often take photos of friends and things in low light, so like fast primes, something m43 seems to excel at. I can only think of keeping the D5000 for 3 reasons: 1. Its intervalometer, in case one day I want to use this function (it sounds fun to do, but I've never got round to it). 2. Better AF for non-pro sports (though I have no long lenses to help here anyway). 3. Flash photography. TL;DR: How do you guys find using the GX1 and its siblings (E-P3 etc.) for these things? Have you had good results using the continuous AF? If I want to go down the strobist route and learn more about flash photography, will the GX1 be as open to me as the D5000?
