f/4 on a full format lens is not that challenging on the A77. Try the max. aperture.

How should the focus be? Optimal for the corner or for the center? Would it be helpful to see a comparison A55 vs. A77 for this corner to judge if the A77 sensor has the same issue as the NEX-7 sensor? Until my A55 is not sold, I could do this comparison. Would it be more meaningful to do this comparison with a wider prime? I could do it with a classical Minolta 28F2. But this lens won't be able to cope with 24 MP anyway, I fear.
