Canon Releases The EOS-1D Mark III Digital SLR
Focus On New and Advanced Professional Features
The EOS-1D Mark III Digital SLR has several new features that make it much more reassuring and confidence inspiring. Highlight tone priority extends the dynamic range of highlights by about one stop and improves gradation within highlight areas. Safety shift lets the camera automatically change the shutter speed, the aperture or even the ISO speed, according to the photographer's choice, even if the light level changes out of the range that the settings on the camera can normally handle, thus avoiding unhappy surprises. In-camera noise reduction for high-ISO images and silent drive mode reduce a different kind of noise: the sound of the camera shutter in a quiet place.
The EOS-1D Mark III Digital SLR is the product of a “reset to zero” design process; absolutely everything was reevaluated. The result is a new and exceptionally easy-to-use set of controls. The 1D Mark III Digital SLR uses a Main Dial, a Quick Control Dial, a Multi-controller, a SET button and several other buttons to select and set various functions. In addition, the ISO speed button, AF Start (AF-ON) button, Picture Style button, and Memory selection/Image size/White balance function button have been newly added to make camera operation faster and easier than previous models. This system follows the logic of the EOS family of cameras. You use the Quick Control Dial to make the selection and press the SET button. When you press a button, it remains active for a while so you can let it go and then turn a dial to set something. You use the Quick Control Dial or the Main Dial to select any of the 19 cross-type AF points. Answering the requests of many current EOS system users, information displays have also been improved. For example, both the ISO speed and the metering pattern in use are now visible at all times, not only on the top LCD data panel, but in the viewfinder as well.
The EOS-1D Mark III digital SLR's power supply is yet another valuable new feature: The camera now uses a new LC-E4 lithium-ion battery pack instead of the previous NP-E3 nickel-metal hydride (Ni-MH) type. As a result, the weight of the 1D Mark III Digital SLR with the battery and memory cards installed is approximately 8 oz. lighter than the EOS-1D Mark II N Digital SLR when comparably equipped, and estimated shooting capacity has significantly improved from 1200 shots for the 1D Mark II N Digital SLR to approximately 2200 shots for the EOS-1D Mark III Digital SLR under normal shooting conditions. Additionally, new technology makes it possible for the EOS-1D Mark III Digital SLR to display battery charge levels in 1percent increments.
The Custom Functions and Personal Functions of previous EOS models have been merged to create an easier to manage set of 57 Custom Functions arranged in four groups according to categories such as exposure and autofocus. Up to six frequently used menu options and Custom Functions can be registered in a new user-friendly feature, called “My Menu.” Up to 10 sets of camera settings can now be saved to one recording medium and moved from one camera to another. Up to five personal white-balance settings and five custom white-balance data items can now be registered.
Major advances have also been made in recording, storage, and playback. For example, in addition to the RAW and JPEG options found in previous EOS Digital SLRs, the EOS-1D Mark III Digital SLR now offers the “sRAW” recording format. “sRAW” has all the flexibility of standard RAW data recording, but at one quarter the resolution and approximately half the file size of conventional RAW images. Another breakthrough option is the ability to record to external USB storage devices connected to the camera via the optional WFT-E2A Wireless Transmitter (see below for more information on the WFT-E2A). Yet another new option is automatic switching of recording media; when the current recording medium becomes full, the camera switches to another automatically and continues recording without interruption. With separate recording, a captured image can be recorded in varying sizes on different media. Each recording medium can be set to record a specific image size (L, M1, M2, S, RAW, sRAW) for each shot. With recording of identical images, the same image is recorded to all recording media. This is also possible with RAW+JPEG and sRAW+JPEG. Any image stored in a memory card or external media can be copied to another installed or connected recording medium.
With the EOS-1D Mark III Digital SLR, if the card slot cover is opened during the writing operation, an alarm sounds and a warning message appears on the screen to indicate that writing is in progress. The card writing continues even if the slot cover is opened. Also, if you set the power switch to the “off” position during the card writing process, a message appears on the screen to indicate that writing is in progress. After the writing is completed, the power turns off.
