New E-P3 with VF-2, four lenses (14-42, 40-150, 45/1.8, 20/1.7) and a spare battery, all in a small Domke bag: total 3.7 lb. Nikon D200 with Nikkor 16-85VR & 70-300VR, Tamron 90 2.8 VR Macro, SB-600 flash, and spare batteries in a Kata bag: total 10.8 lb. Now, I'm not saying this E-P3 can stand up to the way my D200 handles, and I love-love-love the Nikon's control layout. I'm so familiar with it I can operate it almost without looking at it. And I'm not ready to dump my DSLR gear (yet), but for it's weight and size M43 is where the action is as far as I'm concerned, unless you work full time for National Geographic or something. The E-P3 is a dynamite little package, and the 45/1.8 and 20/1.7 are absolutely amazing little lenses. Come to think of it, even if I added the Panny 100-300 I'd like to have, I'd still be under 1/2 the weight of the DSLR kit. The older I get the more I appreciate that. After shooting with the M43 kit for a couple of weeks, I grabbed the Nikon bag to go out and macro some flowers this morning, and it felt like I was carrying a sack of concrete with a shoulder strap. What a difference!
