In the field of photography , a manual focus camera is one in which the user has to adjust the focus of the lens by hand. Before the advent of autofocus , all cameras had manually adjusted focusing; thus, the term is a retronym .
5-491: The Canon T60 was the last manual focus FD-mount 35 mm single-lens reflex (SLR) camera sold by Canon ; it was introduced in 1990, three years after the introduction of Canon's incompatible EOS system of autofocus SLRs and their EF lenses . It was the final camera in Canon's T series . It was introduced solely as a cheap SLR system for export. It was never sold in Canon's home Japanese market. In some foreign markets,
10-440: A variety of ways. Larger view cameras and the like slide the lens closer or further from the film plane on rails; on smaller cameras, a focus ring on the lens is often rotated to move the lens elements by means of a helical screw. Other systems include levers on the lens or on the camera body. There are a number of ways in which focus may be determined. Simplest is using a distance scale and measuring or estimating distance to
15-478: The higher price of the EOS cameras was a problem, while in others, there was demand for a cheap, largely manual camera for photography students and the like. The T60 shared little with the other T-series models except for a superficial styling resemblance. Unlike them, it had only manual film loading, advance and rewind. Film speed and shutter speed were set with traditional dials. The only auto-exposure mode supported
20-439: The subject. Other methods include the rangefinder , which uses triangulation to determine the distance. On other cameras, the photographer examines the focus directly by means of a focusing screen . On the view camera, this ground glass is placed where the film will ultimately go, and is replaced by a sheet of film once focus is correct. Twin lens reflex cameras use two lenses that are mechanically linked, one for focusing and
25-999: Was aperture priority AE. The camera would choose an appropriate shutter speed. Also supported, of course, was full manual exposure, aided by the camera's built-in meter. Shutter speed range was 1/1000 to 1 second, plus bulb . Canon did not manufacture the T60. Like a number of other low-end bodies sold by major camera companies (such as the Nikon FM10 and Olympus OM2000 ), it was both built by Cosina , and based upon Cosina's own CT-1 chassis. (Cosina subcontracted work for many other Japanese photographic firms as well as producing cameras to their own design.)
