Review
Center sharpness at 28mm is outstanding between f/2.8 and f/16. At f/22 sharpness is beginning to drop off a little due to diffraction. Edge sharpness is best between f/5.6 and f/11.
At 75mm center sharpness is a little soft at f/2.8, good at f/4 and outstanding between f/5.6 and f/16. At f/22 sharpness is beginning to drop off a little due to diffraction. Edge sharpness is best between f/8 and f/16.
