Olympus SP-510 Ultra Zoom

The Olympus SP-510UZ (Ultra Zoom) is a 7.1-megapixel bridge digital camera introduced by Olympus Corporation in 2006. It replaced the 6 megapixel SP-500UZ model that was launched in 2005. It was the last model of the SP-series (Special Performance) that used a 10x optical zoom lens. It was also the last of the larger-sized 10x optical ultra zoom cameras to be made by Olympus, which previously was part of the C-series before the SP-series was produced. The SP-510UZ model can be traced back to the C-2100 Ultra Zoom, which was launched back in 2000. The successor model to the SP-510UZ was the SP-550UZ. It used a longer 18x optical zoom lens. Today, the newest model in the Ultra Zoom camera line, the SP-590UZ, features a 26x optical zoom lens. In 2009, Olympus released a compact camera with a 10x optical zoom lens. However, it does not use the Ultra Zoom name nor is it a part of the SP-series line of cameras.

A rangefinder camera is a camera fitted with a rangefinder: a range-finding focusing mechanism allowing the photographer to measure the subject distance and take photographs that are in sharp focus. Most varieties of rangefinder show two images of the same subject, one of which moves when a calibrated wheel is turned; when the two images coincide and fuse into one, the distance can be read off the wheel. Older, non-coupled rangefinder cameras display the focusing distance and require the photographer to transfer the value to the lens focus ring; cameras without built-in rangefinders could have an external rangefinder fitted into the accessory shoe. Earlier cameras of this type had separate viewfinder and rangefinder windows; later the rangefinder was incorporated into the viewfinder. More modern designs have rangefinders coupled to the focusing mechanism, so that the lens is focused correctly when the rangefinder images fuse; compare with the focusing screen in non-autofocus SLRs.

Almost all digital cameras, and most later film cameras, measure distance using electroacoustic or electronic means and focus automatically (autofocus); however, it is not customary to speak of this functionality as a rangefinder.
