EF Lenses
EOS-1D Mark III is compatible with all Canon lenses in the EF lineup, ranging from ultra-wide angle to super telephoto lenses. Canon lenses employ advanced optical expertise and micron-precision engineering to deliver unprecedented performance in all facets of the photographic process. Special optical technologies, such as aspherical optics and fluorite elements are featured in the universally acclaimed L Series lenses, and Canon's Image Stabilizer technology in select lenses minimizes the effect of camera shake. Through Canon lenses, photographers can truly maximize the quality and liberating performance of the 1D Mark III.

Flash Photography
The EOS-1D Mark III features the acclaimed E-TTL II flash metering system. With any of the flashes in the EX Speedlite line, E-TTL II provides reliable flash output whether shooting fill-in flash pictures in sunlight, or using flash in total darkness. The camera’s new 63-zone Evaluative Metering Sensor is also used for flash metering – giving even finer metering command of the image area. If you prefer a broader area for flash metering, Custom Function II-4-1 allows shifting flash metering so that all 63 zones of the sensor are used equally to calculate flash exposures.

Canon's new Speedlite 580EX II is perfectly suited to the 1D Mark III. It has improved reliability of communications through the direct contacts, has a metal flash “foot,” and is dust-/water-resistant as with the 1D Mark III. Other new features include a PC socket on the flash unit, and an external metering sensor for non-TTL auto flash if desired. With the EOS-1D Mark III, you can set most flash settings using the camera’s menu. It has the same power as the previous Speedlite 580EX (maximum guide number of 190 ft./58m at ISO 100) and, when mounted on the camera, automatically compensates for the camera’s sensor size, enabling high output flash, with more flashes per charge. It includes an AF-assist Beam, which works in conjunction with the 1D Mark III’s focusing system, and automatically sends color temperature information to the camera when the flash fires, for more accurate white balance rendition with flash photography.

Wireless File Transmitter WFT-E2A
Canon’s second-generation Wireless File Transmitter WFT-E2A incorporates a number of significant new features into a robust, camera-powered system to make wireless transfer faster, simpler and less cumbersome than ever. WFT-E2A is smaller, attaches to the side of the EOS-1D Mark III, transfers images wirelessly through either 802.11 B or G, has USB and Ethernet connections for situations where wireless access is limited, as well as a more powerful antenna, capable of transmission up to 150 feet from the computer, or an accessory router/access point receiver. It can connect to a third-party GPS device via USB; generating GPS information in the image’s EXIF data. Or, you can plug a compatible USB v.2.0 hard drive into the transmitter’s USB port, and actually shoot directly to a large portable hard drive. Dust- and water-resistance are also matched with the EOS-1D Mark III body. (Note: the previous WFT-E1A Wireless Transmitter unit is not compatible with the EOS-1D Mark III camera.)

Software

Canon EOS Digital Solution Disc (Version 14.0)
The EOS-1D Mark III comes bundled with an updated Canon EOS Digital Solution Disc, which features powerful software programs designed to extend the EOS experience to the computer. These include Canon's ZoomBrowser EX for Windows® (Version 5.8), ImageBrower for Macintosh® OS X (Version 5.8), Digital Photo Professional (Version 3.0), Canon's EOS Utility (Version 2.0), RAW Image Task (Version 2.6), PhotoStitch, and PTP TWAIN Driver. Each application is designed to perfect captured images and streamline the digital workflow. ZoomBrowser EX v. 5.8 and Digital Photo Professional v. 3.0 for Windows are compatible with the new Windows Vista operating system, too.

Digital Photo Professional (Version 3.0) is an image processing program that enables high-speed RAW image processing, high-speed previewing for real-time image adjustment and support for sRGB, Adobe RGB and Wide Gamut RGB color spaces. Because it’s CMS (Color Management System) compatible, Digital Photo Professional allows for easy image layout and printing in Adobe RGB in conjunction with Easy-PhotoPrint and PictBridge printers. It also features the Dust Delete Data Detection tool for cleaner images.

EOS Utility (Version 2.0) for Macintosh or Windows handles the connection between the camera and computer, whenever they're connected via USB. It allows remote controlled shooting from the computer, handles downloading of images from the camera to the computer, and allows seamless linking to either Canon's ZoomBrowser/ImageBrowser or Digital Photo Professional software once images have been copied to the hard drive. Furthermore, it's used to upload settings back into a USB-connected camera.

ZoomBrowser EX (Version 5.8) for Windows and ImageBrowser (Version 5.8) for Mac OS X are the easy, user-friendly options for viewing and editing of JPEG and even RAW image files. Both allow viewing of numerous types of images including finished TIFF and BMP files. Both also have a variety of search options for finding images, allow re-naming of single images or batches of files, and offer a variety of options for printing without using a separate image-editing program.

RAW Image Task (Version 2.6) for Windows/Macintosh
This software is an integrated component of ZoomBrowser EX (Windows) or ImageBrowser (Mac). It allows processing of RAW images from EOS cameras, including the new EOS-1D Mark III, with a variety of adjustment possibilities. These options, as well as the overall color, contrast and “look” of RAW Image Task, closely mimic the characteristics of Canon’s in-camera JPEG processing.
