Ikelite Underwater Housing for 5DIII
Anyone looking to shoot underwater will love our line of Ikelite products. The heavy duty housings are contoured to the camera, completely corrosion free and super durable. The clear case allows for a clear view of the main o-ring seal, port o-ring seal and camera controls as well as allowing you to see any moisture inside, or worse, a leak! We choose to have Ikelite available for rental due to the access of almost every camera control except the multi-controller. This Ikelite housing for the Canon 5DMkIII comes complete with a port and dome that works best with 16-35 f/2.8L II, 17-40 f/4L, 135L or 100 Macro due to lens size and circumfrence. The 24-105L IS and 24-70 F4 IS lenses can also be used, however without the zoom functionality. As a courtesy to our gear cleaning team, try to give the housing a quick freshwater rinse and dry off before sending it back if possible!
All of the photographs below were shot with a Canon 5D Mark III with the Canon L 17-40mm f/4 lens.
