TECHNOLOGIES

This document explains technologies found in the EOS 5D Mark IV

Dual Pixel RAW

Each of the 30 million pixels of the EOS 5D Mark IV is made up of two photodiodes which can be used together or individually. This technology enables the creation of Dual Pixel RAW files which contain a pair of images shot from two very slightly different points-of-view. When processed using Digital Photo Professional software, Dual Pixel RAW files allow photographers to perform one of three types of unique adjustments.

• Image Microadjustment allows the position of maximum sharpness to be adjusted, which is great for fine-tuning portrait images.

• Bokeh Shift allows out-of-focus highlights to be shifted horizontally so they coincide better with in-focus elements.

• Ghosting reduction can be used to reduce the appearance of artefacts like flare.

Digital Lens Optimizer

Canon’s Digital Lens Optimizer technology, which was previously only accessible when processing RAW files in the camera, can now be applied to JPEG files as they are captured. The Digital Lens Optimizer uses optical design values to correct various lens aberrations, diffraction and the softening of resolution caused by the low-pass filter.

IPTC

IPTC (International Press and Tele Communication) is a standard for recording information within images. The EOS 5D Mark IV allows an IPTC template, created in popular software such as Photo Mechanic or EOS Utility, to be loaded to the camera. The IPTC data is then automatically embedded in the image as it is taken as an XMP file, meaning it can be read by all modern photo editing software. This is extremely important for fast paced industries such as news or sports as it saves time adding this data later.

CANON PRESS RELEASE

25 August 2016
 

For photographers in pursuit of the perfect shot –
the EOS 5D Mark IV

Renowned for enabling people to tell the stories that need to be told, the EOS 5D series has captured many of the world’s most significant moments in history. As successor to the EOS 5D Mark III, the EOS 5D Mark IV has been designed using first-hand feedback from the photographic community to create the most versatile EOS model yet.

Featuring a 30.4 megapixel CMOS sensor with wide exposure latitude, 7 frames per second (fps) high speed shooting, internal 4K movie recording and built-in Wi-Fi and GPS, the camera fuses speed and resolution with excellent low-light capability and movie functionality. The EOS 5D Mark IV is also the first EOS camera to premiere the innovative Dual Pixel RAW file format, allowing photographers to fine-tune images in post-production by adjusting or correcting the point of sharpness, shifting the foreground bokeh or reducing image ghosting.

The devil’s in the detail

The EOS 5D Mark IV features Canon’s brand new full frame 30.4 megapixel CMOS sensor, delivering images that are packed with detail, even in the brightest highlights and darkest shadows. With an ISO range of 100 to 32000, expandable from 50 up to 102400, images can be captured in an array of lighting environments. The enhanced noise processing algorithm further improves low light shooting, ideal for photojournalists who need to capture breaking stories no matter what lighting conditions they face.

Tracking faces and colour of fast moving subjects is easy with the 61-point wide area reticular AF system of the EOS 5D Mark IV. The 61-points / 41 cross-type AF points cover an expanded sensor area and provide the ability to focus even under moonlight at EV -3 in viewfinder shooting mode, or EV -4 in Live View mode. The EOS 5D Mark IV enables you to use Extenders with all telephoto lenses for f8 AF with all 61 points, including 21 cross-type for even greater precision. The high-resolution 3.2-inch LCD with full touch panel operation across all menus is combined with a new AF ‘Area Selection’ button providing quick AF point selection. Additionally, the camera features an advanced 150K RGB+IR metering sensor with a dedicated DIGIC 6 processor for accurate exposures and precise subject detection and tracking.

A need for speed

Designed to respond in an instant and never miss a shot, the high-speed readout technologies and DIGIC 6+ processor mean you can shoot at 7 fps at full resolution, with full AF / AE tracking. Capturing up to 21 RAW images or unlimited JPEGs in a single burst, you’ll always be ready for the next frame. For when discretion is needed - such as capturing breaking news or animals in their natural habitat - the camera features ‘Silent Single’ and ‘Silent Continuous’ modes, offering shooting with minimal noise.

Take the jump to 4K movie-making

With the EOS 5D Mark IV, 4K movie-making is open to anyone who wants to use the power of video to tell the bigger picture. A truly versatile camera, it features DCI 4K (4096 x 2160) at 30/25/24 fps shooting and provides the ability to extract 8.8MP JPEG images from 4K videos, making it a great companion for those wanting to easily switch from video to stills. Delivering quality footage has never been more important with streaming services increasingly demanding content be shot using the latest technology in the field. The EOS 5D Mark IV brings this advancement in the form of a video DSLR with internal 4K, 120p HD, Dual Pixel CMOS AF, time lapse movie and new HDR movie mode.

Enhanced operability and connectivity

Packed with a range of new and refined features requested by Canon’s professional community, the EOS 5D Mark IV provides unrivalled flexibility in connectivity. Built-in Wi-Fi enables remote operation and secure file transfer (FTPS/FTP) via smart devices using the Canon Camera Connect app and NFC provides instant connections between compatible devices. GPS geotags each image in the EXIF data with automatic time updates helping to manage images and, for the first time, IPTC metadata, such as details of a shoot, is automatically embedded.

Enhanced water and dust resistance makes the camera ideal for travel photographers or photojournalists working in challenging terrain.

Opening up new viewpoints with unrivalled image quality

Canon is renowned for having the largest lens system in the world and now adds the EF 24-105mm f4L IS II USM and the EF 16-35mm f2.8L III USM to its incredible lineup. A truly flexible and durable everyday lens, the EF 24-105mm f/4L IS II USM is a perfect tool for any photographer wanting to achieve high edge-to-edge sharpness over the entire zoom range. The 24-105mm focal length and f4 aperture is ideal for a variety of scenes, subjects and lighting conditions, while improved 4-stop IS and a new video design EDM provides quiet aperture adjustment during movie capture.

For exceptionally high-quality images that need to impress, Canon is proud to unveil the EF 16-35mm f/2.8L III USM. Working in perfect harmony with high-resolution sensors such as the one seen in the EOS 5D Mark IV, the high-performance lens provides exceptional image quality for professional and serious enthusiasts. The versatile focal length (16-35mm) will appeal to wedding photographers and photojournalists who need to work up close, whilst the fast, constant, f2.8 maximum aperture makes it an obvious choice for those shooting in low light.
