Existing EOS-1D series users will be familiar and comfortable handling the EOS-1D X Mark III allowing seamless navigation with trusted ergonomics - whilst the magnesium alloy body will offer the durability expected from Canon's EOS-1D cameras. Professional photographers can trust the same impressive build-quality as the EOS-1D X Mark II - with phenomenal weather-sealing, standing up to harsh conditions, including wind, rain and humidity. With incredible low-light shooting capabilities, the camera will now feature select illuminated buttons that allow for precision operation in challenging, dark and dimly lit conditions. The camera will also offer a new additional control for selecting AF points, built into the AF-ON button, allowing photographers to change AF points on-the-fly for the best composition - further helping to simplify their work. In addition, dramatically improved battery life - with the same LP-E19 - will allow professionals to shoot for longer periods of time, without having to change batteries, helping reduce the chance of missing a shot.
