The Olympus E-10 is a digital single-lens reflex camera with a 4.0-megapixel CCD image sensor that was introduced in 2000. Unlike most digital SLRs the camera is not a system camera, its lens is fixed to the body. It has a TTL optical viewfinder and a 4× optical zoom lens with lens aperture f/2–2.4. Instead of a moving (reflex) mirror a beam splitting fixed (non-reflex) prism is used to split the image between the optical viewfinder and CCD. Thus it was possible to have a live view on the LCD and in parallel see the image in the TTL viewfinder.
Lens: Non-interchangeable 4 x optical zoom lens, 35 – 140mm, f2.0 – 2.4. ASA/ISO range: 80, 160, 320. Focus modes: Manual, Auto. Shutter: Beam splitting prism. Shutter speed range: 1/640 to 2 seconds, bulb. Viewfinder: Optical TTL through a beam-splitting prism. Rear LCD monitor: 1.8-inch ‘flip-up’
