Hi Gang,
I posted a mini-review of the new small Ikelite housing and ports:

One thing that really impressed me is Ikelite's manual focus port for the 105mm Macro. It has a built-in focus gear in the front of the port that "live" inside the port. It never needs to be mounted on the lens, instead, when the lens is slid into the port, the gear slides right over the rubber focus ring and grips it. It's one less thing to lose. There is an AF-MF shift collar that mounts on the back of the lens and is used with the zoom knob on the housing to shift between AF and MF - pretty nice.
Cheers
James
