Just curious ...
This lens is available for Canon, Nikon and Sony FE. What puzzles me profoundly:
Aperture Blades    9 (Canon), 7 (Nikon), 13 (Sony FE)
Never heard of aperture blades depending on lens mount before! Any insight would be appreciated!


From what I've understood: The canon version has electrical aperture control from the body, the nikon version mechanical control from the body and the sony version only has aperture control on the lens.

Thanks, wasn't aware of the different options for aperture control!
