I am getting a Tokina 10-17 fisheye lens. I previously was using a 10.5 prime fisheye. When using my 10.5 prime I was able to place the low profile "twist lock" port on the housing and visualy check that the the o-ring was not twisted out of place, prior to placing the camera in. Using the Tokina zoom will require the use of the zoom ring, and it seems that it would be difficult to align the tabs in the zoom ring if the port is put on prior to inserting the camera. For those of you Ikelite dSLR housing owners shooting the Tokina 10-17, do you just put the port on after the camera is in the housing, and take a leap of faith that the port O-ring is not out of place?
