Sea & Sea MDX-PRO MKIII Underwater Housing for Canon 1D Mark III and 1Ds Mark III
Review by Eric Cheng and Don Kehoe
Wide-angle Testing
We tested the new 7.2" glass optical dome port with a Tokina 10-17mm lens mounted on a Canon 1D Mark III. A modified gear from a Nikon 18-35mm lens was attached to the Tokina, and the zoom gear on the housing worked flawlessly.

We found that the Tokina 10-17mm lens worked perfectly on the Canon 1D Mark III body (1.3x crop factor) until it was zoomed out to around 12mm. At 12mm, the system vignetted just slightly. Zooming in to 13mm produced images with no vignetting whatsoever.

Additional Testing
I mounted a Canon 100mm macro lens onto a Canon 1Ds Mark III (full frame) and took it under the Blue Heron bridge (using a Sea & Sea flat port). The rig felt comfortable and light in my hands. The "thumb up" focus lever wasn't quite as convenient as are normal levers operated by pushing down, but it still was easy to use. Again, the lack of a return spring was a little annoying because I was never completely sure that the focus lever was disengaged, but I was still able to shoot effectively.

Conclusion
The Sea & Sea MDX-PRO Mark IIIunderwater housing for the Canon 1D Mark III and 1Ds Mark III digital SLR is a fantastic housing, and is in every way worthy of its flagship product status at Sea & Sea. At a retail price of $4,650, it is significantly cheaper than both Subal and Seacam 1D/1Ds Mark III housings.
We highly recommend this housing.

Comment(s):I haven’t actually used the YS-250PRO strobes underwater. Anyone else out there used them?
Posted by Eric Cheng on 03/19 at 09:00 PMAs I take a quick look at the housing pictures there seems to be only one control on the housing’s right side? Zoom control would seem to be the obvious use. Is there no manual focus option for zoom lenses and macro lenses?
Posted by divegypsy on 03/22 at 02:10 AMOne of the nice features on the new Sea & Sea MDX housings is the ability to manually focus macro lens from the zoom control knob. The zoom control knob is on the left side of the housing and easily reachable while your hand is on the grip.
