On October 18 2011, Canon announced a completely revolutionized EOS-1D series camera, the Canon EOS-1D X DSLR camera. The EOS-1D X replaces both the EOS-1Ds Mark III and EOS-1D Mark IV models in Canon's lineup, combining the image quality of the EOS-1Ds and speed capabilities of the EOS-1D Mark IV model. It features a 18 Megapixels full-frame Canon CMOS sensor, Dual DIGIC 5+ Imaging Processors, 14-bit A/D data conversion, 12 fps RAW continuous shooting, a 61-Point High Density Reticular AF (21 focusing points in the central area are standard precision cross-type), a top ISO setting of 204,000 (51,200 native), a 252-zone metering system, and a built-in wired gigabit ethernet network connection for remote shooting and image transfer. The EOS-1D X comes with two new HD video formats to speed up post-production work - intraframe (ALL-i ) compression for an editing-friendly format and interframe (IPB) compression for superior data compression. It also includes two methods of SMPTE-compliant timecode embedding, Rec Run and Free Run, allowing multiple cameras or separate sound recording to be synced together in post production. It can now split movie files automatically when a single file exceeds 4GB, allowing for continuous video recording up to 29 minutes and 59 seconds. The camera records Full HD at 1920 x 1080 in selectable frame rates of 24p (23.976), 25p, or 30p (29.97); and 720p HD or SD video recording at either 50p or 60p (59.94). SD video can be recorded in either NTSC or PAL standards. The camera's letter X represent the 10th generation Canon professional SLR (dating back to the F1 in the 1970s). It is scheduled for March 2012 availability and will be sold in a body-only configuration at an estimated retail price of $6,800.00. Designed exclusively for the EOS-1D X, the new Canon WFT-E6A Wireless File Transmitter features wireless LAN support for 802.11n network transfer. It is dust and weather resistant and can synchronize clocks on multiple cameras to support linked shooting. The WFT-E6A Wireless File Transmitter is scheduled to be available in March 2012 and have an estimated retail price of $600. The EOS-1D X also offers an optional Canon GP-E1 GPS Receiver, which can be easily integrated into the camera's body. It provides the same weatherproof resistance as the EOS-1D X, even at the connector. With an electronic compass on-board, the GP-E1 will log movement - latitude, longitude, elevation, and the Universal Time Code - and allow viewing of camera movement on a PC after shooting. Availability for the GP-E1 GPS receiver is expected in April 2012 with an estimated retail price of $300.
