Roger Cicala from Lensrentals tested the resolution performance of the new and yet non shipping Sony 90mm f/2.8 G OSS macro lens and compared it with the yet best macro lens on market (Canon 100mm f/2.8 IS on 5D III):
At both focusing distances the Sony system is clearly out resolving the Canon system. We would expect that, to some degree, given the higher resolution Sony sensor. But the difference was, quite frankly, surprising to me. It would seem to indicate the new Sony 90mm Macro lens performs at least as well as the Canon 100mm f/2.8 IS L, from a resolution standpoint, anyway.

That sounds terrific! If you want to see a few image samples jump over at Gustavs images on SAR.
