With 42Mp of horse power, the A7R II has slightly less firepower than the Canon 5Ds/5DsR. But without the AA filter on th A7R II, this could result in even more sharpness than the Canon's new but old 5D s/sR.
We somehow get a better clue that this sensor might also be used on the upcoming mystical Pentax Full Frame camera. If so, I guess the Pentax Full Frame will be the only one which still stand the chance to beat this monster.
Lets see what Pentax will bring to the table. If they ever release a Full Frame.
Until then, cheers and take a break.
