A sharpness comparison between the Olympus M.Zuiko 25mm F/1.2 Pro and the Olympus M.Zuiko 12-40mm F/2.8 Pro. The Olympus 25mm F/1.2 is the first lens of Olympus new series of F/1.2 primes. Design and features are similar to other Olympus Pro lenses. There is a good chance, that someone who is interested in the Olympus M.Zuiko 25mm F/1.2 Pro already owns the Olympus M.Zuiko 12-40mm F/2.8 Pro. Therefore, I am going to compare the two lenses in this article. Usually prime lenses are sharper than zooms, however, the Olympus 12-40mm F/2.8 is already a very sharp lens. Will the Olympus M.Zuiko 25mm F/1.2 Pro be able to surpass it or is it “just” 2,5 stops faster?
