On smaller-sensor DSLRs, wide-angle lenses have smaller angles of view equivalent to those of longer-focal-length lenses on 35 mm film cameras. For example, a 24 mm lens on a camera with a crop factor of 1.5 has a 62° diagonal angle of view, the same as that of a 36 mm lens on a 35 mm film camera. On a full-frame digital camera, the 24 mm lens ...
Mounting a lens with optical image stabilization on a camera with in-body image stabilization does not provide improved results, since the combined effect of both systems will "overcorrect". Users of image-stabilized lenses on bodies with sensor-shift IS should determine which system offers superior performance and turn the other off.
The following digicams include a 2 ⁄ 3-inch CCD sensor, a fixed lens with a maximum aperture of f / 2.4 or wider, and SD or CompactFlash (CF) memory card slots. However, none of them support SDHC/SDXC memory cards or AA/AAA batteries. Even larger CCD sensors were only included in interchangeable-lens cameras, such as the Canon 1D, Nikon D60 ...
Compact digital cameras are fitted with fixed lenses, which makes it harder for dust to get into the image area. Similar film cameras are often only light-tight and not environmentally sealed. Some modern DSLRs, like the Olympus E-3, incorporate extensive dust and weather seals to avoid this problem.
Drawing showing the relative sizes of sensors used in most current digital cameras, relative to a 35mm film frame. The image sensor of Four Thirds and MFT measures 18 mm × 13.5 mm (22.5 mm diagonal), with an imaging area of 17.3 mm × 13.0 mm (21.63 mm diagonal), comparable to the frame size of 110 film. [4]
A zoom lens is a system of camera lens elements for which the focal length (and thus angle of view) can be varied, as opposed to a fixed-focal-length (FFL) lens . A true zoom lens or optical zoom lens is a type of parfocal lens, one that maintains focus when its focal length changes. [1]
Polarizing filters reduce the light passed through to the film or sensor by about one to three stops (2–8×) depending on how much of the light is polarized at the filter angle selected. Auto-exposure cameras will adjust for this by widening the aperture, lengthening the time the shutter is open, and/or increasing the ASA/ISO speed of the camera.
