What is Canon Log? Canon Log is a gamm setting that has typically only existed in Canon Cinema EOS cameras. Until now, it has only been available in a DSLR style camera in the EOS-‐1DC. Canon Log extends the range of tones and dynamic range in video recording, providing an even better source file from which to perform extensive video editing or color rendering in post-‐production. This allows the user to achieve a wider exposure latitude and a wide dynamic range of up to 12 stops. Although the 5D Mark IV was originally announced without Canon Log, Canon has received strong requests from professional filmmakers. Therefore, Canon responded to the feedback of the pro community, and announced it on April 20, 2017.
30.4 Megapixel Full-frame CMOS Sensor. The EOS 5D Mark IV camera boasts a full-frame, high-speed CMOS sensor that’s ideal for a broad range of applications with its remarkable high-resolution abilities. Measuring approximately 36.0mm x 24.0mm, the same size and ratio as a 35mm film frame, it records 30.4 effective Megapixels at normal ISOs of up to 32000. It also captures incredible still and 4K video clips suitable for significant post-processing, retouching and cropping. Versatile in virtually all kinds of light and any shooting situation from print and wedding to full-bleed magazine spreads and other commercial or fine art use, the EOS 5D Mark IV consistently produces high-resolution 4K video and image files that are easily compatible with any number of diverse workflows.
ISO 100–32000 (expandable to 50–102400). Featuring an ISO range of 100–32000 (expandable to 50–102400), the EOS 5D Mark IV camera is incredibly well-suited for low-light photography. Its sensor has an improved S/N ratio plus an improved noise-processing algorithm to help deliver high-level light sensitivity along with its high resolution, with virtually no compromise in image quality. Whether working in a dimly lit auditorium, trying to capture the action at night, photographing at the fastest possible shutter speed or simply suppressing camera shake blur, the EOS 5D Mark IV has an extended ISO range that contributes to its ability to excel in nearly every situation it faces.
4K Motion JPEG video at 30p or 24p. The EOS 5D Mark IV is a remarkably capable video camera thanks to its impressive CMOS sensor and its high-speed DIGIC 6+ Image Processor, it can transition from taking still photographs to shooting videos in a near instant, capturing Digital Cinema (DCI) standard 4K (Motion JPEG) videos of 4096 x 2160 pixels at up to 30 or 24 fps. Adding to its versatility, it also supports the 4K broadcasting standard of 3840 x 2160 pixels with slight trimming on the left and right sides. Featuring advanced Live View operation and brilliantly responsive Dual Pixel CMOS AF, the EOS 5D Mark IV has a touch panel display with focus points that can easily be selected during operation, and quickly confirmed by selecting and saving an 8.8-Megapixel image with in-camera 4K still frame grab*. Along with capturing beautiful 4K videos, the EOS 5D Mark IV is equally able to shoot Full HD video at up to 60p plus HD at frame rates as high as 120p, ideal for smooth slow-motion video. It also supports both MOV and MP4 formats for a variety of applications right out of the camera.
