Power Sources The EOS 5D camera is normally powered by one Battery Pack BP-511A/514/511/512. (The BP-511A/514 holds 1,390mAh, 26% more than the 1,100mAh of the BP-511/512.) With a fully charged BP-511A or BP-514, the EOS 5D can take approximately 800 shots at 20°C/68°F or 400 shots at 0°C/32°F. The 5D’s accessory battery grip, the BG-E4, takes up to two of the same series of battery packs, effectively doubling shooting time, or uses six easy-to- obtain AA-size batteries (alkaline, lithium or Oxyride) when using the supplied BGM-E2 battery magazine. Note that alkaline batteries cannot be used at temperatures below 10°C/ 50°F. Conveniently, the BG-E4 has its own Main dial and shutter button for comfortable vertical
shooting. Its front and rear covers use the same magnesium alloy as the EOS 5D’s exterior, contributing to a solid feel as well as a professional, integrated appearance.
A menu item, [Auto power off], allows the camera to go into standby mode after 1,2, 4, 8, 15 or 30 minutes of non-operation. Startup time is approximately 0.2 seconds, virtually instantaneous. Date/time backup is handled by one lithium CR2016 battery with a life of approximately 5 years. An accessory AC Adapter Kit, the ACK-E2, is also available.
E-TTL II Autoflash The EOS 5D camera features Canon’s sophisticated E-TTL II flash control system that incorporates improved flash exposure control, lens focusing distance data and flash color temperature information. The EOS 5D camera has built-in flash exposure compensation and flash exposure bracketing (FEB) with the 580EX, 550EX, MR-14EX and MT-24EX Speedlites. Wireless flash, using these units as well as the ST-E2 transmitter and 430EX or 420EX Speedlites (as slaves only), is possible with as many as three slave groups. High-speed sync (FP, or focal plane, flash) enables flash synchronization at all shutter speeds up to 1/8000 sec. The camera’s hot shoe has a locking pin hole to prevent Speedlite slippage and the PC flash connector is threaded, also for security.
