Want to know more about the R3? Read TechRadar's review here. The Canon EOS R3 Camera
The Canon EOS R3 in all respects appears to be the mirrorless sibling of the 1DX Mark III DSLR, clearly aimed at fulfilling many of the same roles while offering some additional capabilities through the use of the electronic viewfinder and the larger RF lens mount. The full-frame 24.1MP Stacked CMOS sensor, in addition to having incredible low-light performance, can also capture full-width 6K video in both Raw and compressed formats at up to 60fps. The R3 is paired to Canon's industry leading Dual Pixel AF system with 100% frame coverage and the now revived Eye AF system.
Dual Pixel AF II
Canon's Dual Pixel autofocus system has long been a favorite of underwater users, especially when it comes to tacking subjects. With the R3, the system adds an additional 'Animal' recognition mode which might make the system even more reliable at following moving subjects. Frame coverage is 100% with 1053 zones to ensure accurate focus wherever the subject may be. Low Light Performance
The ability to increase a camera's ISO with little penalty is of critical importance to underwater shooters for both stills and video as shooting with higher F-stop values delivers sharper corners and higher shutter speeds mean less motion blur. The higher video frame rates also benefit by allowing the shooter to maintain a 180ยบ shutter while still maintaining adequate aperture values. When using color correction filters, which can often remove more than a full stop of light, compensation via ISO is not as much of an issue for overall image quality. Maintaining dynamic range, even at high ISO levels is also important for those shooting still images using natural light or in poor water conditions. Enhanced Controls
The R3 features an additional control wheel located at the upper right rear of the camera which doubles as the mode control. This wheel can be assigned a variety of functions such as ISO and is adjusted by a dedicated control wheel on the housing within easy reach of the right handle. Video Capabilities
The Canon R3 can capture 6K video at up to 60fps in either Raw or more compressed formats. The 6K capture uses the full sensor width which means no loss in field-of-view. 12-bit 6K capture is possible in both uncompressed Canon Raw or compressed Raw light formats. 10-bit H.265 is also possible in both the HDR PQ and Canon Log3 gamma curves to maximize dynamic range for post processing while maintaining smaller file sizes than a Raw format. It's also possible (when using supported cards) to simultaneously record 10-bit 4:2:2 DCI 4K 60p video. For those looking for higher frame rates, 10-bit 4:2:2 compressed 4K/120fps can also be captured, downsampled from the full sensor width. A natively sampled 4K S35 crop is also an option, allowing for more magnification or the use of APS-C lenses. The R3 also outputs a clean 6K signal over HDMI via an HDMI Micro Type D connector. Direct custom white balance in live view is also now possible, making a critical function for underwater video even easier. Stabilization
The R3 features 5-axis In Body Image Stabilization (IBIS) which can offer up to 8 stops of correction allowing for even smoother video and less camera movement related blur. Large Electronic Viewfinder
The R3's EVF is an OLED 5.76M-dot that features an OVF simulation mode which leverages. the large dynamic range of the OLED screen to reproduce a scene the way it would look through an optical viewfinder. The lower dynamic range of electronic viewfinders has always made them more difficult to use underwater, especially in high contrast or backlit scenes. This function can easily be switched on and off by assigning it to a custom function button. When using the Electronic Shutter, which has an X-Sync speed of 1/180sec, the EVF delivers true no-blackout shooting up to 30fps. The Nauticam NA-R3 Underwater Housing
The Nauticam NA-R3 professional aluminum underwater housing for the Canon EOS R3 mirrorless full frame camera is a tru hybrid shooting solution, just as the R3 itself. Nauticam has continuously supported both the Canon pro-level DSLR lineup as well as the growing full-frame RF-mount mirrorless cameras with innovative underwater housings and the new NA-R3 is the combination of all those technologies. Blending elements of our 1D series housings with those for the R series, the NA-R3 will be the most capable housing for the R3 available. Mission Control
Nauticam engineers design each housing to insure that controls are placed where they are needed most and within easy reach of a natural hand position. The NA-R3 features large knurled control dials for the main and sub-command dials as well as an additional shoulder dial for the customizable control wheel of the R3.
