High Speed Continuous Shooting & Improved AF Performance
With its continuous shooting speed of approximately 8.5fps, the EOS-1D MARK II is the world’s fastest Digital AF-SLR camera (as of January 2004). This record-breaking speed is achieved even when recording in the Large JPEG setting (approx. 3,504 x 2,336 pixels) — a major triumph, considering the EOS-1D’s renowned 8fps continuous shooting speed is accomplished at about half this resolution. Moreover, 8.5fps are maintained during maximum bursts of 40 shots (20 shots in RAW format), whether recording in the One-Shot AF or AI Servo AF mode. Bursts are first recorded to memory to ensure maximum speed and then transferred to memory card for storage. The number of shots remaining during a burst is displayed on the right side of the viewfinder.
In comparison with the EOS-1D, the EOS-1D MARK II offers higher One-Shot AF speed and higher AI Servo AF focusing precision. These improvements are realized by newly employed split multiprocessors that handle AF operations via two CPUs: the AF CPU and camera CPU.
E-TTL II Autoflash
The new improved version of Canon's proprietary Evaluative Through-The-Lens (E-TTL) Autoflash system offers new averaged metering in addition to the evaluative metering available on other EOS models.
Averaged metering employs a new E-TTL autoflash recording algorithm to meter everything at the same distance from the camera, regardless of color, and calculate an accurate weighted average. More stable E-TTL autoflash control, an improvement much requested by EOS users, is the highly beneficial result. Even when a subject changes location, reflectivity or size, this stability in metering helps prevent underexposure and overexposure. Lens distance information is also taken into account, when available, to enhance metering stability should mirrors, white plates or other highly reflective objects be present in the frame.
Apart from the addition of averaged metering and the absence of infrequently used depth-of-field AE, the EOS-1D MARK II offers the same AF modes, metering modes and other shooting modes as the EOS-1D, but with numerous improvements.
Custom & Personal functions
By taking advantage of Custom Functions and Personal Functions, users can easily tailor the EOS-1D MARK II to meet their own specialized needs.
21 Custom Functions are provided with 67 settings and various improvements requested by EOS-1D users. These include the removal of the ISO speed extension setting to the ISO speed extension menu, the addition of new E-TTL averaged autoflash metering, and the inclusion of AI Servo continuous shooting, which was previously a Personal Function.
25 Personal Functions can be installed in the camera at any time, via driver software, to meet high-level customization needs. New features include the ability to append data for data verification and the ability to apply the Quick Control Dial's ON/OFF switch to the Main Dial to prevent accidental changes to settings when shooting remotely with EOS Capture.
Another requested feature, the ability to save and read camera settings, is now also possible. Almost all camera settings that appear in the top LCD panel, rear LCD panel, and menus (including Custom Functions and Personal Functions) can be saved to a memory card and later reloaded for use by simply inserting the card.
Designed as a serious tool for professionals, the EOS-1D MARK II performs reliably in the most demanding shooting conditions. Its handsome body offers the same high durability as the EOS-1Ds, thanks to rigid magnesium alloy in the chassis and external covers (top, front, rear and memory card slot cover). The Magnesium alloy also contributes to effective electromagnetic shielding, a long-lasting luxurious finish, and extremely low body weight that landscape photographers will surely appreciate.
Exceptional durability extends to the inner mechanisms as well, which are shielded from dust and water by protective sealing on all exposed moving parts. Improvements include shutter durability which, at 200,000 shutter cycles, is 30% higher than in the EOS-1Ds.
