The Canon EOS 7D is the company’s answer to rival Nikon’s D300s. Both of these cameras are intended for advanced amateurs and budding professionals who demand features necessary to create spectacular photos with excellent color reproduction and sharp images.
The EOS 7D boasts of an 18-megapixel APS-C CMOS sensor. With this level of resolution, you can crop your pictures and enlarge them without any significant loss of detail. Apart from capturing still photos, the camera is also capable of recording 1080p HD videos. Exposure control can be adjusted manually, and you can even choose the frame rate.
In addition to an Intelligent Viewfinder, you can also use the 3.0-inch Clear View II LCD monitor for picture composition. It has 920,000 dots guaranteeing sharp images during both composition and playback.
Although the body of the EOS 7D is made of magnesium alloy that is dust and weather-resistant, it is not equipped to deal with a more radical exposure to the elements. It cannot resist water and therefore is unable to capture images from under the seas. In order not to miss out on this opportunity, it has to be encased in an underwater housing. One possibility is the Aquatica Underwater Housing that is dedicated to the EOS 7D.
Aquatica housings are machined from solid aluminum, after which they are treated and anodized to a level on par with military specifications. The housing is finished with a polyurethane powder coating that is electrostatically applied and heat-treated. This provides a robust protection against wear and the effects of exposure to adverse weather conditions.
Being made of aluminum, the Aquatica housing is lightweight. In spite of this, it is strong enough to have a depth rating of 300 feet. The port mount is bayonet-type making it easy to install or uninstall ports. The port is wide enough to allow changing camera lenses without having to take it out of the housing. All camera controls are accessible including video controls. And in case you want to record dolphin sounds along with the video, you can install an optional hydrophone.
Bulkheads and connectors for external flashes are also provided on the housing.
