Quality

To measure and compare the sharpness of the Canon EF-M 32mm f1.4 STM lens, I photographed the following scene with it and the EF-M 15-45mm at 32mm at all aperture settings. When set to 32mm, the EF-M 15-45mm has a maximum aperture a tad larger than f5.6, so crops from it start in the sequence below at f5.6 onwards. The crops are taken from the areas marked by the red rectangles.
