Just before switching from DSLR to Mu-43, from the gargantuan proportions of the D700 to the toy-like proportions of EP-1, I took a side road. I tried out an Olympus E3 in a camera store and I was hooked. It was soooooo much smaller than the Nikons I was using. The salesman convinced me that Olympus optics matched, no exceeded, Nikon at every focal length and the E-3 was a stylish looking piece of equipment that brought me back a little to my old OM's. So, the promise of the future and the past all rolled into one system. I only shot the E3 for a matter of months when the E5 was introduced and I traded up quickly. Shot that for about a year and then switch to Mu-43 and, so far, never looked back. Anyone else take this detour? I wonder yet what stalled the Four Thirds format. Why wasn't it more popular? Why didn't it sell better? I admit I left it in fear of Olympus abandoning it altogether and so far that hasn't happened. But it hasn't seemed to grow much either.
