Keep your Aquatica O-Ring Kit for A7r II Underwater HousingA7r II underwater housing watertight with this O-Ring Maintenance Kit. For complete camera compatibility information, please see below. The kit contains a full set of replacement O-rings for the enclosure, i.e., one large main seal and two smaller seals for the port and extension, along with a container of silicone lubricant to keep the rings from drying out and cracking.

Aquatica's neoprene O-rings are built to withstand extreme temperatures and are highly resistant to harsh solvents. After changing any O-ring, a pressure test or immersion without a camera inside the housing is mandatory. Failure to perform this test could result in serious damage to your camera and lens if the O-ring is improperly installed.

Q: 4. Is this housing compatible with the Ikelite AF35 strobe?

A: The Ikelite AF35 strobe is NOT compatible with the Ikelite Underwater Housing for Canon PowerShot G7X Mark II. You need to use a strobe that uses a fiber optic cable. Please email uw@bhphoto.com for compatible strobe options.

Q: 5. Can I use this housing with a canon 5d mkii and a 24-70 lens?

A: The Ewa-Marine U-AZ housing is fine for the Canon 5D mark II but not the Canon EF 24-70mm f/2.8L II USM lens. This housing bag is designed for lenses that are 9 long and have a 62mm filter thread or smaller. The Ewa-Marine U-B 100 is a better choice. This bag housing is compatible with lenses that are 3.94 to 7.87 long and have a filter thread of 82mm or smaller. For the Canon EF 24-70mm f/2.8L II USM lens you will need the Ewa-Marine C-A82 82mm Adapter Ring Set.

A: You could switch between photo and video mode when the Sony a7 IV camera is in the Ikelite Underwater Housing for Sony a7 IV.

Q: 9. Hi, Is this compatible with SONY A7S III? Thank you.

A: No, it is not. The Ikelite 200DL Underwater Housing with Dry Lock Port Mount for Sony a7S III, B&H # IK200HSAA7S3, would instead be the correct underwater housing designed for use with the Sony Alpha a7S III Mirrorless Digital Camera.

Q: 10. What length lens does this fit?

A: The Ikelite Sony A7IV pictured here does not come with the required domes/ports. For typical use, you would purchase the dome/port that matches the lens you plan on using. We are unable of sharing external links via this system, but please visit Ikelite's website and they have an extensive list of the ports required to fit the 71479 housing.
