The TTArtisan 40mm f2 Full Frame AF Prime Lens (for L-Mount cameras) delivers a natural 57° angle of view, combining a fast maximum aperture with a compact, all-metal design. Its optical construction features aspherical, extra-low dispersion, and high-index elements for clarity and minimal aberrations. The STM motor provides quick, quiet autofocus with face detection support, and a USB-C port in the rear cap enables easy firmware updates.
