Canon EF-S 60mm f/2.8 Macro USM Lens Port 52 for Sea & Sea MDX-7D/40D Underwater Housing | SS-30111
Every underwater macro shooter knows that perfect moment. The one where a tiny nudibranch or a brilliantly colored shrimp emerges from the reef, and you need absolute sharpness and the right port to capture it. This port is built for that exact scenario. It’s a dedicated housing port for the Sea & Sea MDX-7D and MDX-40D housings, designed to accept the Canon EF-S 60mm f/2.8 Macro USM lens with a Port 52 gear system.
- The port itself is purpose-built for the 60mm macro lens, which means you get full access to the lens’s focus ring and manual focus clutch without any awkward extensions or wobble. Everything aligns precisely, and the gearing feels solid when you rack focus underwater.
- It works seamlessly with the Canon EF-S 60mm’s f/2.8 aperture, letting you maintain bright viewfinder visibility even when you’re cranking in to 1:1 life-size magnification. That extra stop of light matters a lot when you’re working in dimmer reef cracks at depth.
- Construction is straightforward and robust?this is a part of the Sea & Sea ecosystem, so it matches the MDX-7D and 40D bodies with the same locking mechanism and o-ring seal you’d expect from a system designed around reliability in saltwater. You aren’t fighting alignment issues when you attach it.
- Because this port is matched specifically to the 60mm’s short working distance, you can stay closer to your subject than with a generic port, reducing backscatter from particles in the water column. It’s a small advantage, but it genuinely improves your macro shots.
