I have the new / modified wide body, and the original control would not actuate the focus collar of the 105 VR. I snt it back to Ikelite and the put the "old style" control with a larger rubber sheath (instead of an o-ring) in the focus port. Now it works fine.
I just recently got everthing fixed and back from my flood incident. I was in Roatan last week and tried out the 105 VR again. Even with the new wider port, I still have to be very careful putting the port on so that the M/A swich doesn't get moved. For the life of me I still can't get the lens to manual focus at all. I think that I will give ikelite a call as soon as I get back from my Canada trip. Maybe they need to modify mine also.
