Resolution
Our Applied Imaging tests reveal the 28mm to behave much as we’d expect for a fast prime. It’s pretty sharp in the centre of the frame wide open, but the edges lag behind. Peak central sharpness is achieved at f/4, with best overall sharpness around f/8-f/11. At smaller apertures the image softens due to diffraction.
