Canon's EF-mount system surrounds the groundbreaking 50.6-Megapixel Full-Frame CMOS imaging sensor. The mount allows you to use any EF, and if you choose, EF-S lenses. This leaves you with a huge collection of Canon and third party lenses to choose from, so there is always a great lens for any situation.
The highest resolution sensor in the EOS line, the new 50.6-Megapixel sensor offers the highest level of quality and detail. To help the camera with this large sensor and large image files, it works with dual DIGIC 6 image processors to keep quality and performance at its best. Canon even developed a new "Picture Style", fine detail, that adjusts the cameras settings to collect as much detail as possible.
With no built-in flash, you will have to rely on an external speedlite for an on-camera flash unit, which Canon offers several options. Even radio wireless control is possible when using the Canon Speedlite 600EX-RT. Other accessories like a GPS unit or Wireless File Transmitter can also be used with the hot shoe.
On the left is the camera's mode dial. A very simple mode dial, lacking all of the automatic and special shooting modes normally found on beginner and enthusiast dSLRs. The 5Ds does feature Canon's Scene Intelligent Auto though, just in case you are stumped by a shooting situation. On the other end of the spectrum, you will find 3 completely customizable shooting modes, which are great for situations that you shoot on a regular basis. The button in the middle of the dial must be pushed in order to unlock the mode dial, preventing you from bumping it and changing your shooting mode by accident.
For Live View and Video shooting, you will be using the camera's 3.2-inch, 1.04-million dot Clear View II LCD screen shows approx. 100% field of view. The high-res screen features manual and automatic screen brightness adjustment and an anti-reflective AR coating to make it easy to see in almost all light conditions.
On the top right side of the camera you will find several camera controls, that are extremely familiar to Canon users. The top command dial, WB, Drive/AF, ISO/Flash Exposure Compensation and LCD light are all standard to Canon EOS cameras. As is the LCD info screen, which can even be found on the new Rebel T6s.
On the back right side of the camera you will find several more common controls to a Canon camera. At the top left is the Still Image/Video switch. Inside the switch is the button to start and stop video recording as well as turning on Live View when the camera is in still image mode. To the right of the switch you will find the AF start, AE lock and AF point selection buttons. Under them are the multi-control, Quick control button, Quick Control dial/set button and the multi-function lock switch.
On the back left side of the camera you will find the MENU and INFO buttons at the top. They are followed by the Creative Photo, Rate, Index/Magnify, Playback and Delete buttons.
