Canon EOS 5D Mark IV is designed

EOS 5D series is arguably one of the most recognizable camera lines of the digital age and the Mark IV is designed to appeal to the same wide range of enthusiasts and professionals. Nearly identical-looking to its predecessor, it receives substantial upgrades under the hood, including: a higher-resolution sensor with Dual Pixel autofocus, 4K video capture, an upgraded AF system, a touchscreen, improved weather-sealing, built-in Wi-Fi/NFC, an interval timer and GPS. All this adds up to a camera that fits into Canon's product line nicely as the all-around full-frame option...

It is built around a new 30.4MP CMOS sensor and uses the Digit 6+ processor. The AF system is from the flagship 1D X Mark II and contains 61 AF points (41 of which are cross-type) with up to 24% expanded vertical coverage compared with the system in the Mark III. The center point is sensitive to -3EV in One Shot (AF-S) mode (in Live View the sensor is sensitive to -4EV with a fast lens).

4K video capture is a welcome addition to this camera and users can record in either 24 or 30p, albeit with a 1.64x crop. All footage is captured as Motion JPEG. Additionally, the camera allows for 4K Frame Grabs, effectively giving users 30 fps stills shooting with (Dual Pixel) AF. We've seen that the camera suffers from some rolling shutter, but it may still have some merit for capturing the decisive moment when 7fps just isn't enough.

While developing the IV, Canon says it sought feedback from 5D-series users and found that dynamic range, resolution, AF precision and AF speed where the four most important areas improvements were requested. On paper, the Mark IV seems to address these aspects nicely.

In terms of AF, the increased coverage area is part of what makes the upgrade a big deal: after all, it's the same AF system found in the company's flagship sports camera. The 150,000-pixel RGB-IR metering sensor, which feeds scene information to the AF system, is borrowed from the original 1D X, bringing enhanced subject identification (including faces) and tracking ('iTR'), as well as improved metering and flicker detection
