Canon EOS 400D
The EOS 400D, called Digital Rebel XTi in North America and EOS Kiss Digital X in Japan, is an entry-level digital single-lens reflex camera introduced by Canon on 24 August 2006. Details It is the successor of the Canon EOS 350D, and upgrades to a 10.1 megapixel CMOS sensor, a larger continuous shooting buffer, an integrated image sensor vibrating cleaning system (first used in a Canon EOS DSLR), a more precise nine-point autofocus system from the EOS 30D, improved grip, and a bigger LCD with 230,000 pixels and a larger viewing angle which replaces the top status screen. The 400D uses the DIGIC II image processor, as is used in the 350D. The 400D file numbering system holds 9,999 pictures, as opposed to 100 photos in one folder with the 350D. Support for the Media Transfer Protocol (MTP) USB protocol is available since version 1.1.0. The latest firmware available is version 1.1.1. It was succeeded by the Canon EOS 450D (Rebel XSi in North America) which was announced at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Autofocus
An autofocus (or AF) optical system uses a sensor, a control system and a motor to focus on an automatically or manually selected point or area. An electronic rangefinder has a display instead of the motor; the adjustment of the optical system has to be done manually until indication. Autofocus methods are distinguished as active, passive or hybrid types. Autofocus systems rely on one or more sensors to determine correct focus. Some AF systems rely on a single sensor, while others use an array of sensors. Most modern SLR cameras use through-the-lens optical sensors, with a separate sensor array providing light metering, although the latter can be programmed to prioritize its metering to the same area as one or more of the AF sensors. Through-the-lens optical autofocusing is usually speedier and more precise than manual focus with an ordinary viewfinder, although more precise manual focus can be achieved with special accessories such as focusing magnifiers.

Canon EOS 40D
The Canon EOS 40D is a 10.1-megapixel semi-professional digital single-lens reflex camera. It was initially announced on 20 August 2007 and was released at the end of that month. It is the successor of the Canon EOS 30D, and is succeeded by the EOS 50D. It can accept EF and EF-S lenses. Like its predecessor, it uses an APS-C sized image sensor, resulting in a 1.6x field of view crop factor. Improvements Changes over the 30D include a higher-resolution sensor (10.1 megapixel instead of 8.2). The sensor also has better noise control than previous models. The 40D has a larger memory buffer so more pictures can be taken in succession without a slow down in frame rate. Frames per second has been increased from 5 to 6.5. The 40D adds a new format, Canon's sRAW, which is a smaller RAW image for smaller prints and reduced file sizes. The 40D's RAW format is 14-bit instead of the 12-bit of the 30D. The camera uses the new DIGIC III image processor, which was first used in the Canon ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Fill Flash
Fill flash is a photographic technique used to brighten deep shadow areas, typically outdoors on sunny days, though the technique is useful any time the background is significantly brighter than the subject of the photograph, particularly in backlit subjects. To use fill flash, the aperture and shutter speed are adjusted to correctly expose the background, and the flash is fired to lighten the foreground. Most point and shoot cameras include a fill flash mode that forces the flash to fire, even in bright light. Depending on the distance to the subject, using the full power of the flash may greatly overexpose the subject especially at close range. Certain cameras allow the level of flash to be manually adjusted e.g. 1/3, 1/2, or 1/8 power, so that both the foreground and background are correctly exposed, or allow an automatic flash exposure compensation. Pros and cons of near-axis fill flash The advantage of using a fill flash located near the lens axis is "normalizing" exposur ...

Flash Sync
In photography, flash synchronization or flash sync is the synchronizing the firing of a photographic flash with the opening of the shutter admitting light to photographic film or electronic image sensor. In cameras with mechanical (clockwork) shutters synchronization is supported by an electrical contact within the shutter mechanism, which closes the circuit at the appropriate moment in the shutter opening process. In electronic digital cameras, the mechanism is usually a programmable electronic timing circuit, which may, in some cameras, take input from a mechanical shutter contact. The flash is connected electrically to the camera either by a cable with a standardised coaxial PC (for Prontor/Compur) 3.5 mm (1/8") connector (as defined in ISO 519), or via contacts in an ''accessory mount'' (hot shoe) bracket. Faster shutter speeds are often better when there is significant ambient illumination, and flash is used to flash fill subjects that are backlit without motion ...

Film Speed
Film speed is the measure of a photographic film's sensitivity to light, determined by sensitometry and measured on various numerical scales, the most recent being the ISO system. A closely related ISO system is used to describe the relationship between exposure and output image lightness in digital cameras. Relatively insensitive film, with a correspondingly lower speed index, requires more exposure to light to produce the same image density as a more sensitive film, and is thus commonly termed a ''slow film''. Highly sensitive films are correspondingly termed ''fast films''. In both digital and film photography, the reduction of exposure corresponding to use of higher sensitivities generally leads to reduced image quality (via coarser film grain or higher image noise of other types). In short, the higher the sensitivity, the grainier the image will be. Ultimately sensitivity is limited by the quantum efficiency of the film or sensor. Film speed measurement systems His ...

Nikon D60
The Nikon D60 is a 10.2-megapixel Nikon F-mount digital single-lens reflex camera announced in January 2008. The D60 succeeds the entry-level Nikon D40x. It features the Nikon EXPEED image processor introduced in the higher-end Nikon D3 and D300. Like a number of other entry-level Nikon DSLRs, the D60 has no in-body autofocus motor, and fully automatic autofocus requires the use of a lens with an integrated autofocus-motor.

Kit Lens
A kit lens is a "starter" lens which can be sold with an interchangeable-lens camera such as a single-lens reflex camera. It is generally an inexpensive lens priced at the lowest end of the manufacturer's range so as to not add much to a camera kit's price. The kit consists of the camera body, the lens, and various accessories usually necessary to get started in SLR photography. A kit lens can be sold by itself outside of a kit, particularly the ones that are moderately expensive; for instance a kit lens included in a prosumer SLR kit is often marketed as an upgrade lens for a consumer SLR. In addition, retailers often have promotions of standalone low-end SLR bodies without the lens, or a package that bundles the SLR body with one or two more expensive lenses. Originally kit lenses were of normal focal length; more recently kit lenses tend to be inexpensive zoom lenses that range from medium wide angle to mid telephoto for added versatility. Prime lenses are generally faster ( ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Live-preview Digital Camera
Live preview is a feature that allows a digital camera's display screen to be used as a viewfinder. This provides a means of previewing framing and other exposure before taking the photograph. In most such cameras, the preview is generated by means of continuously and directly projecting the image formed by the lens onto the main image sensor. This in turn feeds the electronic screen with the live preview image. The electronic screen can be either a liquid crystal display (LCD) or an electronic viewfinder (EVF). Background The concept for cameras with live preview largely derives from electronic (video) TV cameras. Until 1995 most digital cameras did not have live preview, and it was more than ten years after this that the higher end digital single-lens reflex cameras (DSLR) adopted this feature, as it is fundamentally incompatible with the swinging-mirror single-lens reflex mechanism. The first digital still camera with an LCD for autogain framing live preview was the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
