7Artisans is teasing a new MAX autofocus ultra-wide-angle lens. The clue they provided is the number 012456 – four of those digits are for the focal length and the aperture. Maybe 15mm f/2.4?
Update – this is probably the 7Artisans AF 10mm f/2.5 fisheye lens:
7Artisans will announce a new AF 10mm f/2.5 MAX full-frame fisheye lens on July 28 (E/Z/L)
