As you can probably tell, there is plenty of sharpness. I have read alot of rewievs tough, that says there is no or little CA. i would not agree. there is CA in alot of the pics. The picture of my grandma for example. Look at the crop of her glasses, its tack sharp, but there is CA in there. Aswell as in the crop from the sign, there is little CA around the letters in the sticker.
But contrast and sharpness is great! and the lens is lighter then i expected 🙂 And it looks damn good on the A7r!
