Overview The Pentax Electro Spotmatic was the world’s first 35mm SLRA single-lens reflex camera (SLR) is a camera that typically uses a mirror and prism system (hence "reflex" from the mirror's reflection) that permits the photographer to view through the lens and see exactly what will be captured. With twin lens reflex and rangefinder cameras, the viewed image could be significantly different from the final image. When the shutter button is pressed on most SLRs, the mirror flips out of the light path, allowing light to pass through to the film. Other camera typoes include DSLR, Rangefinder and Compact.

CCDs are considered to the older technology and although most current digital cameras use CMOS sensors they are still widely used and many photographers seek out older cameras with CCD sensors because of their colour and image characteristics. CCD image sensors are widely used in professional, medical, and scientific applications where high-quality image data is required CCDs use a global shutter, which exposes the entire image simultaneously. This can lead to blur if any motion occurs in the image during exposure, but a high shutter speed prevents this problem. Whereas CMOS sensors are equipped with ‘rolling shutters,’ which expose different parts of the frame at different points in time. This can lead to skew, wobble and partial exposure in photographs. CCD sensors create low noise images but consume 100 times more power than a similar CMOS sensor.   More. The shutter controls the exposure time, which can range from thousandths of a second to several minutes or more. Fast shutter speeds […]
