Meikon a7RII zoom adjust

I modified the Meikon a7RII case for zoom adjust with the 16-35 mm and 24-70 mm lens in their dome.  The adjuster is composed of two plastic gears, one wrapped around the lens barrel, and the other located in a small side-mounted  attached to the side of the extension from the housing to the dome itself.  It is actuated by a lever from the left hand.  No vacuum leaks and no water leaks in a tub.  Next step, dive to 60 ft.

A small mill and lathe were required to do this mod and I wouldn't have done it without those tools plus lots of spare time.  It was a cheap mod, which is why I undertook it; and it's part 3 of the 4 mods I've planned for the Meikon case.

Meshed large and small gears.
