Design

Building upon the very successful EOS-1D, Canon ups the ante with the EOS-1Ds and an amazing 11.1-megapixel, full-frame CMOS sensor. (The earlier EOS-1D was an exceptional camera in other respects with its 4.0-megapixel CCD, and extraordinary 8 frames/second shooting speed.) Weighing in at a hefty 44.6 ounces (1,265 grams) without the battery, lens, or CompactFlash card installed, the Canon EOS-1Ds is more than a handful. Its magnesium-alloy body is exceptionally tough and durable, ready for heavy use. Size and portability weren't top design considerations for the 1Ds. Instead, Canon opted for maximum speed, ruggedness, and compatibility with the EOS-1v film camera, and the EOS-1D digital SLR before it. The EOS-1Ds has the same dimensions as its predecessor, measuring 6.1 x 6.2 x 3.1 inches (156 x 157.6 x 79.9mm ), and definitely requires a two-handed grip.

The resemblance between the EOS-1Ds, EOS-1D, and the film-based EOS-1v is more than close -- the three cameras are virtually identical. All of the conventional controls (AF, Mode, Drive, ISO, Exposure Compensation, etc.) are exactly the same, except for the obvious differences, such as those digital controls that simply don't apply to a film camera, and the lack of a film compartment door -- but everything that can be the same is. This extends even to the Custom Function options. In some cases, Canon has left an "empty" function on the 1D, simply so the function numbers shared with the 1v and 1D will be the same. If you're comfortable using an EOS-1v or 1D, you'll be able to transition to the 1Ds with almost no learning curve, and switching rapidly back and forth between any of the three models should involve no confusion.

One of the most welcome aspects of the EOS-1Ds' design is that it needs little protection from the elements. A feature inherited from the EOS-1v and carried forward through the 1D, its weatherproof body features rubber-sealed compartments and controls (with no fewer than 72 sealing components), making the camera ideal for shooting in any type of inclement weather -- driving rain, snow, dust storms, or mud -- it should make little difference to the 1D. Though it's not certified for submersion, I'm willing to bet you could give it a quick dunk with no ill effects. This is a huge advantage over other pro digital SLRs on the market today (October, 2001), and I think it will be of major significance to practicing pros.

Though the lens mount itself also doesn't feature any environmental sealing, Canon introduced a lens mount with the EOS-1v, continued on the 1D, and now on the 1Ds that accommodates a rubber sealing gasket on the lens body. The combination of gasket seat (on the camera) and gasket (on the lens) makes for a water and dust-tight seal between the camera body and lens. Canon tells us that all future L-series lenses will likely incorporate this type of gasket. (It doesn't interfere with the lens mount on older Canon SLRs, but it doesn't provide the sealing that it does on the 1v, 1D, and 1Ds.) For now though, there's a pretty complete range of focal lengths available with the sealing technology. (Missing only the focal length range from 35-70mm.) A list of current EF-mount lenses incorporating the gasket appears above right.


The front of the EOS-1Ds is simple in design, essentially identical to the preceding 1D model, featuring only the lens mount and a few controls. A small release button on the right side of the lens (as viewed from the front) releases the lens from its mount, allowing you to remove it completely. The hefty hand grip is big enough to provide a secure hold on the camera, even with a lens attached. At the bottom of the hand grip is a secondary shutter button and Command dial, for use when holding the camera vertically. Also visible from the front of the camera is the main Shutter button, mounted at a sloping angle from the top panel, as well as the front of the battery compartment. (The latter being the low bulge along the bottom of the camera that also serves as the vertical-orientation hand grip.) Hidden on the right front side is the ambient-light White Balance sensor, covered by a white diffuser window. This sensor helps the camera determine the proper color balance, using its "hybrid" white balance technology. Finally, the Depth of Field Preview button can be seen on the left side of the lens mount, with the self-timer lamp above it.

The right side of the camera (as viewed from the rear) holds the secondary Flash Exposure Lock button; the On/Off switch, which activates the secondary camera controls; the secondary function dial; and the secondary shutter button. At the top of the right side is one of the eyelets for attaching the neck strap.

Lining the opposite side of the camera are the Flash PC socket, Remote Control, and Digital input jacks, each covered by a flexible synthetic rubber flap. At the bottom is the battery compartment and its release controls–a rotating latch and a release button, both of which must be activated to open the compartment door. Though I found this system a little difficult to operate at times, it does ensure that the battery stays in place, and won't accidentally end up on the ground. Also on this side is the other neck strap eyelet.

The EOS-1Ds' top panel holds several camera controls, including the Mode, AF, Drive, ISO, Metering/Flash Exposure Compensation, LCD Illumination, Exposure Compensation, Flash Exposure Lock, and Shutter buttons. A small Command dial is located just behind the Shutter button, and is used to adjust camera settings. (The Command dial is used by itself to set aperture and shutter speed in some modes, or works with the plethora of other buttons to engage the actual setting changes.) The external flash hot shoe crowns the camera's top panel, and a small, black-and-white LCD monitor reports camera information such as battery power, exposure mode, aperture, shutter speed, and exposure compensation, among others.

The remaining camera controls are located on the back panel, along with the LCD monitor and optical viewfinder eyepiece. A diopter adjustment dial and the optical viewfinder eyepiece shutter flank the eyepiece on either side. A removable soft rubber eyecup (included in the box with the 1Ds, but not shown above) attaches to improve viewing in strong ambient lighting. In the center of the back panel is a large Quick Control dial, which also selects camera settings when turned on (a small switch above the dial turns it on or off). While it does work in conjunction with some of the camera's buttons, the Quick Control dial primarily serves as part of the user interface for the LCD menu system. Camera controls on the back panel include the Assist, AE Lock, AF Point Selection, Sound/Protect, Menu, Select, Display, Erase, Quality, and White Balance buttons. In the lower right corner are the secondary Assist, AE Lock, and AF Point Selection buttons, for use when holding the camera vertically. The 2.0-inch LCD monitor displays image playback and menu screens, and a secondary, black-and-white LCD panel just below it reports more camera information. Also on the back panel is the CompactFlash card slot, released by turning the small release key just below it.

The bottom panel of the EOS-1Ds holds only a tripod socket and a strap attachment eyelet used for the short strap shipped with the 1Ds, that wraps around the user's right hand when he/she grips the camera, providing a more secure grip. The tripod mount is directly below the centerline of the lens, reducing parallax errors between shots when panning.
