I currently own an Olympus E-Volt 500, which has served me well when my skills were more limited than they are now. Wanting to move up to a prosumer level camera, naturally I would like to stick with Olympus because I already own the lenses and their 4/3 system is not compatible with third party lens manufacturers. The Olympus E-30, or whatever iteration in the next generation would be the one. The only problem is that Olympus is apparently going out of the DSLR cameras, hinging their star to the EVF-IL types. They have produced only one new DSLR camera in two years, and that one is to replace their professional E-3 with the E-5. Since it is evident that Olympus is not going to support their DSLR lines with new models, it is apparently time to switch. I'm currently looking at the cameras in the topic line and would like to know pros and cons. I've handled both of them and both are far heavier than my Olympus and a bit more cumbersome to use. But they are what they are, and it's evident I'll have to get used to one of them. So, any reasons why I should purchase one over the other? I realize the initial investment, which includes replacing all my lenses is going to be rather steep.
