The Mark Of Ascendancy, Canon EOS IDS Mark II... 16.7 Megapixel 35mm full-size CMOS Sensor: Originally developed by Canon, this new super-high resolution CMOS sensor features a record-breaking 16.7 million effective pixels. The same size as 35mm film (36 x 24mm), it also brings out the full potential of Canon's professional EF lenses. From smooth gradations & wide ISO speed range to effective suppression of noise & false colors, this sensor meets the highest expectations of the most demanding professionals. High Speed High Quality Digic II Imaging Engine: DIGIC II processes the massive data generated by the extra-large 16.7-megapixel imaging sensor at extremely high speed, resulting in high-precision images, natural color reproduction & highly responsive user-friendly operation. Approximatly 4-FPS Continuous Shoting , for up-to 32 Shots: The accelerated image processing of DIGIC II combines with high-speed data reading from the imaging sensor to achieve fast continuous shooting at approx. 4frames per second for maximum bursts of 32 shots in JPEG Large (11 shots in RAW). Remarkably Responsive Performance: The EOS-1Ds Mark II is ready to shoot just 0.3 seconds after turning on its power. More shots can also be taken in less time, thanks to a short shutter-release time lag, faster data writing to media, and a viewfinder blackout time of approximately 87 ms at 1/60 or faster shutter speeds. With the new EOS-1Ds Mark II, you'll be ready whenever shutter opportunities arise. Refined Basic Functionality: Canon EOS-1Ds Mark II inherits a number of leading features from its EOS digital predecessors, including E-TTL II autoflash, an RGB histogram display, dual card slots (CF Card and SD Memory Card) & a 230,000-pixel high-precision LCD monitor. It also offers an ISO speed range of 100 to 1600 with selectable 50 & 3200 settings via extension menu. Designed for Profesionals: The EOS-1Ds Mark II is based on the highly acclaimed EOS-1Ds, but satisfies the higher demands of today's professionals. Viewfinder coverage is 100%, since the effective area of its CMOS sensor is the same as 35mm film, & wide-angle lenses can be used in exactly the same way as on 35mm cameras. Simultaneous recording of RAW and JPEG image data, without any speed penalty, supports a highly efficient workflow. Moreover, shutter speeds range from 30 to 1/8000 sec., with an X-sync at 1/250 sec. Durable Magnesium Alloy Body: The EOS-1Ds Mark II meets the demands of professional field photographers. Lightweight and highly rigid, its magnesium alloy chassis & external covers (top, front, rear & memory card slot covers) contribute to excellent durability and electromagnetic shielding. Moving parts are tightly sealed to ensure water and dust resistance on a par with the EOS-1Ds. And the exceptionally reliable performance includes a shutter durability of 200,000 cycles. The Mark II is compatible with numerous advanced accessories.
