Bridge Camera

Bridge Camera

Prosumer cameras (AKA Bridge Cameras) are cameras which fill the niche between the single-lens reflex cameras (SLRs) and the point-and-shoot camera. They are often comparable in size and weight to the smallest digital SLRs (DSLR), but almost all digital bridge cameras lack an optical viewfinder system (film bridges generally had a lighter version of a reflex finder). In addition, SLRs normally feature interchangeable lenses, while current bridge cameras do not. The phrase has been in use at least since the 1980s, and continues to be used with digital cameras. The term "Bridge camera" was originally used to refer to film cameras which "bridged the gap" between point-and-shoot cameras and SLRs.

Like other cameras, most current bridge cameras are digital. These cameras typically feature full manual controls over shutter speed, aperture, ISO, white balance and metering. Generally, their feature sets are similar to consumer DSLRs, except for a smaller range of ISO sensitivity because of their typically smaller image sensor (a DSLR has a 35mm, APS, or 4/3 size CCD or CMOS). Many bridge cameras have long zoom lenses, so the term "bridge camera" is often used interchangeably with "megazoom", "superzoom", or "ultrazoom." However, some bridge cameras have only moderate or short zooms (such as the Canon Powershot G9), while many compact cameras have superzoom lenses but lack the advanced functions of a bridge camera.

With zoom ranges and sales rapidly increasing in the early 21st century, every major camera manufacturer has at least one 'super zoom' in their lineup.

Famous quotes containing the words bridge and/or camera:

    I was at work that morning. Someone came riding like mad
    Over the bridge and up the road—Farmer Rouf’s little lad.
    Bareback he rode; he had no hat; he hardly stopped to say,
    “Morgan’s men are coming, Frau, they’re galloping on this way.
    Constance Fenimore Woolson (1840–1894)

    If I were just curious, it would be very hard to say to someone, “I want to come to your house and have you talk to me and tell me the story of your life.” I mean people are going to say, “You’re crazy.” Plus they’re going to keep mighty guarded. But the camera is a kind of license. A lot of people, they want to be paid that much attention and that’s a reasonable kind of attention to be paid.
    Diane Arbus (1923–1971)
