The Canon EOS 30D is an 8.2-megapixel semi-professional digital single-lens reflex camera, initially announced on February 20, 2006. It is the successor of the Canon EOS 20D. It can accept EF and EF-S lenses, and like its predecessor, it uses an APS-C sized image sensor, so it doesn't require the larger imaging circle necessary for 35 mm film and 'full-frame' digital cameras. The Canon EOS (Electro-Optical System) autofocus 35 mm film and digital SLR camera system was introduced in 1987 with the Canon EOS 650 and is still in production as Canons current SLR system. ...

Improvements

Changes over the 20D include a bigger 2.5-inch LCD rear screen, improved shutter mechanism rated for 100,000 actuations, improved frame capacity, 1/3 stop increments for sensor speed and an added spot meter. The camera retains the same sensor as its predecessor; all lenses still have an angle of view crop of 1.6. Other changes include a larger 11 frame RAW / 30 frame JPEG buffer, and slightly faster 0.15 second startup. The maximum frame rate is the same (5 fps), but a lower-speed 3 fps option has been added. The 30D uses the same number of autofocus points as the 20D (nine), but has improved algorithms. The 30D can record in both JPEG and RAW .CR2 files. The camera shows the ISO in the view finder while changing the ISO. A cameras angle of view can be measured horizontally, vertically, or diagonally. ...

The EOS 30D can also accept the Canon Wireless File Transmitter WFT-E1/E1A for fast file transfer to a remote file server, either through an ethernet cable or a Wi-Fi network. This capability expands the EOS 30D's range of applications to sports and news photojournalism and studio set ups where real-time transfer of the images is crucial.

Resolution

The Canon EOS 30D has several resolution settings:

• Large/Fine (3504 x 2336)
• Large/Normal (3504 x 2336)
• Middle/Fine (2544 x 1696)
• Middle/Normal (2544 x 1696)
• Small/Fine (1728 x 1152)
• Small/Normal (1728 x 1152)
• RAW .CR2 format (3504 x 2336)
• (There are also six resolution settings for JPEG+RAW which are the same as the first six but which also attach a RAW file in a separate .cr2 file).

Features

The Canon EOS 30D features a Mode Dial on the top which lets you select the shooting mode for each situation. It is divided into two sections: Creative Zone and Basic Zone. Obviously the Creative zone is dedicated to a more professional shooting audience, yet it gives the user more advanced options to change such as the RAW shooting function and manual exposure, aperture and ISO sensitivity, which can only be set under the Creative zone. Each function is explained below: A raw image file (sometimes written RAW image file ) contains minimally processed data from the image sensor of a digital camera or image scanner. ...

Film speed is the measure of a photographic films sensitivity to light. ...

Creative Zone:

• A-DEP: The camera automatically selects the aperture and shutter speed to keep most of the image in focus. (Only recommended in high light conditions as the camera tends to choose smaller f/stops)
• M (Manual): The camera lets you choose manually the aperture and shutter speed.
• Av (Aperture priority): The camera lets the user choose the aperture (f/) value and then automatically adjusts the shutter speed for correct exposure.
• Tv (Shutter speed priority): The camera lets the user set the shutter speed and automatically sets the aperture for correct exposure.
• P (Program AE): The camera automatically chooses an aperture and shutter combination for correct exposure and the user can change between one of these combinations.

Basic Zone:

• Auto (represented with a green rectangle): Completely automatic shooting.
• Portrait: The camera tries to blur the background for better looking portraits.
• Landscape: For shooting landscapes and sunsets.
• Close-Up: For shooting small objects near to the camera.
• Sports: For capturing fast moving objects.
• Night Scene: Shoots with flash and with slow shutter so that the subject is illuminated by the flash and the background (e.g: a city) is also captured naturally in the night.
• No Flash: All automatic with no flash.

The camera features (like many others) two LCDs, one monochrome at the top, which contains all information pertinent to shooting, and a full-color one at the back, which is used for picture reviewing and menu navigation.

The Canon EOS 30D also features a large dial on its back which is used for fast scrolling over the stored pictures or over the settings in the menu.
