When digital cameras became common, a question many photographers asked was whether their film cameras could be converted in the direction of digital. The answer was yes in addition to no. On behalf of the majority of 35 mm film cameras the answer is no, the reworking in addition to cost would be too great, especially as lenses have been evolving as well as cameras. On behalf of most a conversion in the direction of digital, in the direction of give enough space on behalf of the electronics in addition to allow a liquid crystal display in the direction of preview, would require removing the back of the camera in addition to replacing it in the midst of a custom built digital unit.Digital China reflector telescope cameras are made in a wide range of sizes, prices in addition to capabilities. The majority are camera phones, operated as a mobile application through the mobile phone menu.
Professional photographers in addition to many amateurs use larger, more expensive digital single lens reflex cameras (DSLR) on behalf of their greater versatility. Between these extremes lie digital compact cameras in addition to bridge digital cameras that bridge the gap between amateur in addition to professional cameras. Specialized cameras including multispectral imaging equipment in addition to astrographs continue in the direction of serve the scientific, military, medical in addition to other special purposes on behalf of which digital photography was invented.Compact digital camera are usually designed in the direction of be easy in the direction of use, sacrificing advanced features in addition to picture quality on behalf of compactness in addition to simplicity, images can usually only be stored using less compression (JPEG). Most have a built in flash usually of low power, sufficient on behalf of nearby subjects. Live preview is almost always used in the direction of frame the photo. Most have limited motion picture capability.
Compacts often have macro capability in addition to zoom lenses but the zoom range is usually less than on behalf of bridge in addition to DSLR cameras. Generally a contrast detect autofocus system, using the image data from the live preview feed of the main imager, focuses the lens.Bridge is higher end digital cameras that physically in addition to ergonomically resemble DSLRs in addition to share in the midst of them some advanced features, but share in the midst of compacts the use of a fixed lens in addition to a small sensor. Like compacts, most use live preview in the direction of frame the image. Their autofocus uses the same contrast detect mechanism, but many bridge cameras have a manual focus mode, in some cases using a separate focus ring, on behalf of greater control. They originally bridged the gap between affordable points in addition to shoot cameras in addition to the then unaffordable earlier digital SLRs.
