Light capture on m43 at f2.8 is NOT comparable to a FF f5.6. If that reasoning were correct, all of the f2.8 APS-C lenses would really be f4.0 lenses. An f2.8 is an f2.8 on any format in terms of light gathering. DoF, and size, is the only difference.
Time to switch to Corel and Photo Ninja. I guess Adobe thinks they are enough of a standard that stupid customers will be willing to "rent" the software. NOT.
Buy a Sony A65 and get Tamron 17-50 / 70-200 f2.8 lenses. You get excellent IQ, 24MP / excellent color depth / as well as image stabilization on every lens since it is in body. That means you can take a fast prime, open it all the way and shoot in dark environments.
