Canon EOS R Underwater housing by Sea&Sea

With the Canon EOS R, underwater photographers not only get a full-frame mirrorless camera with Canon's Dual Pixel autofocus and the ability to use the EF-S range with an adapter, but also the new RF mount, which enables new lenses with groundbreaking features. The EOS R features a 30.3 MP full-frame CMOS sensor with the new RF lens mount and a 3.7-million-dot electronic viewfinder. The Canon EOS R Camera The Canon EOS R is remarkable not only because it is Canon's first full-frame mirrorless camera, but also because of the many additional features available with the introduction of the RF lens mount. The RF lens mount has the same large diameter of 54mm, but the ability to use larger rear lens elements that are closer to the sensor increases the sharpness in the corners and at the outer edge. The lenses can also be more compact than lenses with the same coverage area in the EF mount. The addition of 4 more lens communication pins to a total of 12 pins expands the functionality of the lenses. RF lenses feature a customizable control ring that will also be available on one of the two EF mount lens adapters and can be assigned to control various exposure settings. On the RF lenses, manual focus is now controlled electronically, which allows the direction of rotation of the lens' manual focus ring to be changed. The EOS R is also able to use the wide range of EF-mount lenses üvia three optional adapters: a simple EF-to-R adapter, an adapter that supports the customizable control ring, and another that offers a drop-in filter port. The features that have made Canon DSLR and Cinema cameras favorites of underwater photographers are also present in the EOS-R, including powerful and precise Dual Pixel autofocus and 4K Canon Log video recording üvia the large 30.2MP CMOS full-frame sensor. Important Camera Specifications 30.3MP CMOS full-frame sensor 8fps continuous shooting 4K UHD recording at up to 30 frames per second All-I ISO 100-40,000   The NA-R underwater gear from Nauticam. The NA-R underwater gear embodies Nauticam's drive for innovation. Both the Canon EOS R and Nikon Z-7/6 cameras offer photographers the ability to use available äolder lenses üvia an adapter in addition to the original optics.  For many, the EOS R is a transition from a Canon full-frame DSLR. To support both conventional and original lenses, Nauticam has integrated the NA-R into the N120 port system.. Use lenses with RF or EF mounts - with the same port system. Canon's EF-to-RF adapters can be attached to the camera before insertion into the housing.  When using the EOS R inside the housing with the adapter and a supported EF lens, the port and port extension are identical to the same arrangement on a Nauticam Canon N120 DSLR. As the range of RF lenses evolves, dedicated port and port extension combinations will be listed in the port overview.   Two lens release buttons, one for RF lenses and one for EF lenses used with the optional Canon adapter, are located on the front of the housing to facilitate lens removal through the portöopening.   Controls. Nauticam engineers are obsessed with giving the photographer unobstructed access to all necessary controls underwater, with as many as possible within easy reach of the ergonomically rubberized grips.  This mission control philosophy extends to the NA-R, which features a dual thumb lever and dual sub-lever on the right grip.   The thumb lever activates the "AF-On" buttons and the lower one activates the "Info" buttons, while the lower lever corresponds to the "M-Fn" and "Record" buttons.  Next to the left grip is a thumb lever for "Playback" as well as a dedicated switch for switching from LCD to EVF.   Large, knurled and rubberized knobs access the camera's "main"and "sub"command controls.  The two-stage off"ser enables smooth focus and off"activation. Additional buttons for "Menü", "focus point selection" and others are also "easily accessible via the handles.. An additional control wheel is located on the left side of the housing and connects to the control ring on the supported EF to EOS R mount adapter with control ring üvia the optional gear (NA19561). Flash triggering Flash output is via one of two optional flash outputs, a manual LED output (NA26301) or a TTL flash output (NA26321), which use the built-in fiber optic ports with optional fiber optic cables to output supported flash units. For control of flashes that do not support fiber-optic flash output, a variety of older flash sockets are available. Video üvia HDMI  The EOS R is capable of outputting a 10-bit 4K UHD (3840 x 2160) 30p video signal üvia HDMI.  When combined with the optional standard M16 HDMI jack (NA25033) and HDMI (D-C) 190mm cable (NA25036), the NA-R can be used in conjunction with an external monitor or recorder such as the SmallHD 502B or Ninja Inferno in their respective Nauticam housings. Vacuum test and leak detection system  The NA-R is supplied with the electronics as well as the M16 II vacuum valve for vacuum testing and the leak detection system. This simple system makes it possible to check the waterproof integrity of the housing before the dive and to monitor it continuously throughout the dive. The Nauticam system is temperature compensated, eliminating false alarms caused by a  change in external temperature or by heating a camera during an action-packed dive.
