THE CANON 5DS AND 5DS R

For anyone interested in high-resolution, Canon has announced two 50 Megapixel DSLR cameras aimed squarely at still photographers, the EOS 5DS and EOS 5DS R. The models are identical with the exception of the low pass filter (5DS) versus an optically self-cancelling low pass filter (5DS R). These cameras are very similar in functionality to the Canon 5D Mark III, and share the same body dimensions. The main difference, besides over double the pixels, has to do with taking advantage of all that resolution. The more resolution the sensor offers, the more detail that can be captured. However, this also means that it can capture things like camera shake, shutter/mirror flap and soft focus extremely well also. Canon has gone to great lengths to minimize these effects by doing things like changing the type of motor that drives the shutter to allow it to decelerate as it opens fully.

The cameras also offer a mirror lockup mode to put some delay between the mirror opening and the capture, allowing the user to choose the time for mirror vibration to subside – maximizing sharpness while minimizing the loss of responsiveness. The body is more rigid than the 5DIII, and Canon even went so far as to reinforce the tripod socket to reduce any potential wobble when mounted on a tripod.

THE NAUTICAM NA-5DSR HOUSING

Clearly a camera of this magnitude deserves the very best housing to take it underwater. Existing NA-5DMKIII housing owners – stop reading here, because that housing will work flawlessly with the 5DS. But Nauticam is unable rest on laurels, and so simply had to produce the NA-5DSR, refining the NA-5DMKIII housing just that much more. The Nauticam NA-5DMKIII has been incredibly popular and well liked among it’s users. Many of the controls for the NA-5DSR are based on the NA-MKIII, taking advantage of how solid that housing is. Still, the Nauticam designers were able to make improvements. Small changes, to be sure, but each incredibly well thought out – designed by underwater photographers, for underwater photographers.

As an example of a minor but important change, the right side of the housing has been made less “crowded” by moving the video/still switch to the top of the housing, and combining the ISO and DOF preview buttons in a tactile rocker that makes accessing both controls exceptionally easy. Perhaps the biggest change is the addition of the patent pending multi-controller. This moves the joystick control closer to the right hand, making it easier to get to. The piano keys for Set and Q were beautifully sculpted to make room for it, yielding a user interface that is both beautiful and functional.

Simple buttons like Menu, Picture Style, Rate, Magnify, and Trash have been given an angled treatment, making it easier to reach these buttons with the left hand. The shutter is the new paddle style - exceptionally easy to use even when wearing thick gloves, yet retain amazing tactile feel for use of the half-press of the 5DS shutter. The NA-5DSR includes strobe mounting balls and lightweight laser cut stability brackets.

USE WITH CANON 5DMKIII

Since the 5DS, 5DS R and 5D Mark III share the same basic camera body, this housing can be used interchangeably with all three cameras. This provides incredible flexibility… shoot for high resolution with the 5DS R on one dive, then switch to the 5D Mark III for it’s superb low light capability.

Finally, the NA-5DS is quite a bit lighter than the original NA-5DMKIII… so much so that the amount of added buoyancy needed for most applications is reduced or eliminated. The result is a housing that is a dream to handle underwater.

VIEWFINDERS

The standard optical glass viewfinder is very good and travel friendly, but many photographers prefer the ease of a magnified viewfinder with adjustable diopter. Nauticam produces a “straight” 180º enlarging viewfinder and a 45º angled enlarging viewfinder to enhance the ease of close quarters work often associated with macro shooting. Both viewfinders have high quality optics, and allow bright viewing of the entire image. A patented external dioptric adjustment allows personal adjustment to a sharp-as-a-tack standard underwater and viewfinder changes can be executed in less than 30 seconds without using tools. Exceptional composition and focus accuracy have never been more accessible.

PREMIUM PROFESSIONAL OPTICS

Experienced shooters know a camera is only as good as the lens in front of it, and the same is true when choosing optics for an underwater camera system.  Four optically coated glass dome ports (250mm, 230mm, 180mm, and 140mm diameters) and a series of acrylic ports support popular lenses from Canon, Sigma, and Tokina.  Port configurations are extensively tested at Nauticam to determine the ideal extension ring length for best performance.

For macro and super macro shooting, the Nauticam Super Macro Converter is a revolutionary accessory. This is an entirely in-house design, optimized for use in water.  The water contact correction offers the highest overall sharpness, free from chromatic aberration and purple fringing, with reproduction ratios exceeding 2:1 when used with a EF 100mm f/2.8L IS USM Macro Lens.
