Olympus has relatively inexpensive high performance lenses when used on their bodies. One advantage is the micro 4/3 coverage circle. I believe that Olympus's sin was not moving aggressively enough in the pixel wars(Leica seems to be coming around to high pixel count sensors even though many of their lenses aren't designed around that concept: the APO Summicrons being the exception at a steep price). I hope that another major manufacturer will come around to 24x36 sensor coverage lenses where the camera corrects flaws in the lens. I believe this is best done by the body manufacturer as they have the room to put the ROM that would correct during internal processing for lens flaws. In a mature state the camera and lens would talk to each other about focus distance, aperture, and zoom setting if applicable. Imagine where you could go from 0.95 Canon massive spherical aberration to L mount 35 APO Summicron correction just by a menu selection. My bias is I really like extremely well corrected lenses but cringe at the size and weight to get there. Look at the MTF charts for the L mount APO 35 Summicron compared to the MTF of the M mount version: over 90% transfer at F2 across the field at even high frequencies compared to dipping to only 60% transfer for the M mount on the edges. But then compare the size and weight of the two; I believe most people would make the compromise for the lower size and weight.
