I use the 9 to 18 zoom for wide angle with the E-3 and E-620 with great results using the Olympus 170 mm dome port.
I would expect the M9-18 zoom to be as sharp a lens as the 4/3 lens, the issue is how well it will work behind the flat port with this new housing. The flat port will reduce the angle of view for sure and I would expect that corner sharpness will suffer as well. For most photographers this may not be a deal breaker vs. the many upsides compared P&S camera systems.
