In line with previous members of the main 5D series, the Mark IV attempts to balance high resolution with low-light performance with a newly developed 30.4MP full-frame CMOS sensor. This provides a beneficial increase in overall resolution without compromising on sensitivity. Additionally, thanks to the DIGIC 6+ image processor it is paired with, it offers impressive performance within a native range of ISO 100-32000, which can be expanded to ISO 50-102400.
First implemented here on the 5D Mark IV, Dual Pixel RAW allows photographers to record all the information the sensor’s unique pixel architecture can deliver, providing a way for fine adjustments to be made after the image is taken. These adjustments include focus fine tuning that can help you ever-so-slightly adjust the focus point to bring out extra details, shift bokeh around for improved composition, and reduce the impact of ghosting on your photos.
Designed for both professional stills shooting and video recording, the 5D Mark IV supports DCI 4K (4096 x 2160) resolution recording at up to 30 fps at 500 Mbps, along with Full HD 1080p shooting at 60 fps and HD 720p at 120 fps for slow motion playback. When recording in-camera, 4K video has 4:2:2 sampling and 8-bit color depth, while Full HD 1080p footage has 4:2:0 sampling. Uncompressed Full HD 1080p video can also be saved via HDMI to an optional external recorder with 4:2:2 color sampling. 4K video is recorded using a central 4096 x 2160 area of the sensor at a 1.74x crop in order to record video with an ideal 1:1 pixel sampling ratio, while Full HD recording makes use of the entire full frame.
