There's a lot of heat regarding 4/3 mirrorless not performing as well as current full frame (24x36) DSLR. Disregarding DoF differences due to differing format sizes, how many years back do we have to look to have state-of-the-art FF DSLR sensor dynamic range, resolution, pixel count, maximum frame rates etc. just match or begin to exceed mu-43 cameras available in stores right now? This will be a bit of a history lesson for me because I've only had an interchangeable lens digital camera for less than 2 years. I'm trying to gain some perspective on the progress Olympus and Panasonic engineering teams have been making and possibly what they've been aiming for.
