Hello , The Sony Zeiss 24mm is supposed to be among the best APS-C e-mount lens optically , however I have noticed softness in my images so I did a quick test... When I focus for the best sharpness on the right side , the left side is OOF and vice versa. I can try to compromise between left and right sharpness and I get less then optimal sharpness on both sides. Stopping down to f/8 f/11 helps to some extent. Sample 1 @f2.8 Right side in focus: r.JPG Left side in focus: l.JPG Attempted compromise: l.JPG Sharp across the frame at f/8 _DSC0089.JPG Sample 2: @2.8 Right side in focus: r2.JPG Left side in focus : l2.JPG Sharp across the frame at f/8 f8.JPG For some reason I can't upload these to the forum , just double click to view at 100% Would appreciate some feedback , do you believe this lens is faulty ?
