According to Digicame-info, the EOS 5D Mark IV is said to sport a 30.4MP CMOS sensor. It will also come with a dual pixel AF CMOS system, 61 AF points, a 150,000 pixel RGB + IR photometry sensor, anti-flicker, the ability to continuously shoot at 7 frames per second, and an ISO range of 100-102,400.
Canon also appears to be giving the camera some more modern features, like a touch panel. It will also have WiFi and GPS built into it, and will support media cards like SD, SDHC, SDXC, and CompactFlash Type II. It will also be both dust and water resistant, and will also be able to record 4K video at 30fps which is actually rather decent.
No word on when the camera will be launched or how much it will cost, but typically Digicame-info’s information leaks pretty close to the official announcement, so we’ll be keeping our eyes peeled for more info, until then take it with a grain of salt.
