Precision 5" Dome Port
Designed specifically for the Tokina 10-17mm lens & Ikelite dSLR housings
By Michael Zeigler
Looking for a dome port for your Tokina 10-17mm fisheye lens? I was too, and that's when I found out about the Precision 5" Dome. What's great about this dome port is that it's designed specifically for the Tokina 10-17mm lens, and my Ikelite housing.
I find that the Precision Dome attaches easily and securely to my housing via the four port-locks, and its small size makes packing easy. But more importantly, it allows me to take some great underwater photos.

The Precision Dome details
The Precision 5" Dome is manufactured based on calculations using the nodal point of the Tokina 10-17mm fisheye lens and the Ikelite dSLR housing. The calculations define the distance between the lens nodal point and the dome, resulting in sharper edge-to-edge focus when compared to other generic dome ports. A wider angle of view is achieved from the use of a half-sphere dome.
The small size allows you to get extremely close to your subjects, which is great for close-focus wide-angle photography.
You will need the Ikelite 5510.11 or 5510.10 super-wide-angle port body with the dome. Another option is to use a 1.4 teleconverter (Kenko Teleplus Pro 1.4x) in conjunction with the Ikelite 5510.16 standard zoom port body.
Benefits of the Precision 5” Dome
Ultra sharp with the Tokina 10-17mm lens
Better edge-to-edge image sharpness than other generic domes
Absolutely no vignetting with the shade
Small size allows you to get closer to your subjects - great for CFWA shots!
Very small and light - makes packing and traveling with your equipment so much easier
Acrylic material means light scratches will generally not appear in photos. Deeper scratches can be "meshed out" with an acrylic mesh kit.
All domes are vacuum leak tested
