It's been a little more than 4 year since Canon unveiled the EOS 5D Mark III. Today, Canon took the wraps off its successor -- the EOS 5D Mark IV. The Mark IV features a 34-megapixel, full-frame CMOS sensor and Digic 6+ processor with support for capturing 4K video at 23.98, 24, 25 and 30 fps. In addition, it features a 61-point autofocus system, built-in digital lens optimizer, NFC, Wi-Fi and an ISO range of 100-32,000. The continuous shooting mode is set at 7 fps, compared to 6 fps on the 5D Mark III. It will also take both CompactFlash and SD cards, and there is GPS included in the body for geotagging images. Canon is selling the Mark IV in early September for $3,499 for the body only. They're also selling two new L-series EF lenses -- the Canon EF 16-35mm f/2.8L III USM Ultra-Wide Zoom Lens and EF 24-105mm f/4L IS II USM Standard Zoom Lens. President and COO, Canon U.S.A., Inc, Yichi Ishizuka said in a statement: "Canon's EOS 5D series of DSLR cameras has a history of being at the forefront of still and video innovation. And today, we add to this family of cameras the EOS 5D Mark IV -- the first in our 5D series to offer 4K video and built-in Wi-Fi and NFC connectivity. In developing this new DSLR camera, we listened to the requests of current EOS users to create for them a modern, versatile camera designed to help them create and share beautiful still and video imagery."
