Sealux CD300 Housing for the Nikon D300 Review

Whilst my previous two Sealux housings were functional and durable (see http://www.underwaterdisplay.net/rig for reviews) the CD300 shows an improvement in aesthetics and ergonomics with the introduction of some subtle changes including: curved handles and conically tapered flat ports for close-up and macro work.

A feature on Sealux housings which I think is a good design attribute is the raised inner lip on the housing body which stops water falling back into the housing when the housing back is removed after a dive. This also serves as a guide to placement of the lid on the housing body for sealed closure.

Attention to detail is evident in the design of the CD300. Mineral glass rather than polycarbonate is used for the window over the D300 monitor display and this does justice to the resolution and clarity of the D300�s display. This is an important feature and one which rated highly in my deciding whether to purchase. The monitor window is visible with the 150 degree viewfinder rotated to any of its selectable positions. As with other Sealux DSLR housings, tested depth rating is given as 90 metres.

The CD300 allows for an additional ball mount to be installed in the threaded socket provided on the centre top of the housing to mount a focus light or other accessory. This effectively gives four possible mounting points on the housing for strobes and accessories; one on each arm, a third one on the left hand side and the ball mount at centre top. Two different size ball fittings are available. The additional ball mount can be unscrewed to allow the housing to fit in my cabin bag without the ball protruding.
