Rate & Review


The Sea & Sea Extension Ring 46 with Focus Knob provides manual focus for compatible zoom lenses (Extension ring equipped with port lock). Until now, auto focus has been the only option available when using a zoom gear. With the new Extension Ring 46 with Focus Knob, you can now manually focus a compatible zoom lens. When your camera's AF frames do not cover your subject, you can manually focus a compatible lens without changing composition.

This product is the ideal solution when you shoot fast-moving subjects (which even the latest auto focus may not follow) or when you shoot in dark environments and when there are lots of particles suspended in the water; all situations where auto focus will not function correctly. The focus knob is located in an ideal position and angle to be easily operated with the index finger and thumb.

The extension ring is compatible with MDX series housings and Canon EF 16-35mm F2.8L ll USM, Canon EF 17-40mm F4L USM, AF-S Nikkor 18-35mm F/3.5-4.5G ED, AF-S Nikkor 16-35mm F/4G ED VR lenses.

Note! Compatible FC focus gear required for manual focusing (can be used in conjunction with a compatible zoom gear).
