Olympus M.Zuiko Digital ED 25mm f/1.2 PRO Review
Sharpness at 25mm
The sharpness tests for this review were carried out using a real-world subject rather than a test chart. The Olympus M.Zuiko Digital ED 25mm f/1.2 PRO lens was attached to an Olympus OM-D E-M1 Mark II, which was in turn mounted on a sturdy tripod. Exposure delay mode was activated to prevent camera shake. Any tonal or colour variances you see between the images are due to natural changes in light during the shooting session.
The full frame at 25mm
Centre sharpness is high from wide open (f/1.2) up to f/11. It is only the narrowest aperture available, f/16, which seems to suffer from diffraction issues, being slightly softer when viewed at 100%. The edges aren't as sharp as the centre, with sharpest results at f/5.6-f/11.
