Canon unveiled the new Canon EOS 1D Mark IV Digital SLR camera. The new EOS 1D Mark IV is, according to Canon, a high-speed multimedia performance monster.
Features of the Canon EOS 1D Mark IV include 16MP Canon CMOS sensor, 3-inch display Dual DIGIC 4 Imaging Processors, 14-bit A/D data conversion, all at 10 frames-per-second (fps), with the widest ISO range (ISO 100-12,800 / Expansion settings of L: 50 for bright light or H1: 25,600, H2: 51,200, and H3: 102,400) Canon has produced to date.
The new EOS 1D Mark IV camera also features 1080p Full High-Definition video capture at selectable frame rates packaged in Canon's most rugged and durable professional camera body.
Another highlight of the Canon 1D Mark IV Digital SLR is its new autofocus system that starts with 45 AF points including 39 high-precision cross-type focusing points capable of tracking fast moving athletes or wildlife accurately at speeds up to 10 frames per second.
With greater subject detection capability than ever before plus a newly redesigned AI Servo II AF predictive focusing algorithm, the Canon EOS-1D Mark IV camera sets new standards for autofocus performance among professional digital SLRs.

The Canon EOS 1D Mark IV is available for pre-order for $4,999.99 on Amazon.com.

The Canon EOS 1D Mark IV competes directly with the new Nikon D3s, which was announced last week. The Nikon D3s also offers extreme ISO, but a smaller sensor. The D3s also sells for around $5,000.
