| other | like most recent Sony lenses, focuses stopped down at your selected aperture. This means that autofocus performance steadily drops as you stop down, since smaller apertures mean less light, and more depth-of-field (less phase difference) for the autofocus system to work with. By F9, phase-detect fails altogether, and you'll experience significant hunting in AF-C. | faster AF than the Sony 35mm |
