This aperture series from f/1.8 through f/9 evaluates the Sony FE 14mm f/1.8 GM for overall performance across the frame and near to far. Focus was carefully placed to deliver maximum total sharpness.
This series includes an additional frame focused at greater distance. It is an excellent demonstration of how lens skew (optical swing) can throw off sharpness along the entire side of the frame.
