Following up their 24mm model, Global Dynamics United grows their lens portfolio with a ruggedized version of the full-frame 40mm Canon f/2.8. Just like the previous lens, the 40mm gets that mil spec 7075 aluminum housing that looks like it came straight off of Iron Man and removes the manual focus ring to avoid accidental adjustments. It also features a built-in UV filter and is compatible with the Canon EF mount and a variety of cameras with an adapter.
