Zoom-lens reflex camera - Zoom lens reflex might refer to an SLR (or dSLR) type camera with a zoom lens which can not be removed. No such camera currently exists, as all fixed lens cameras either use an electronic viewfinder (EVF), or a separate optical finder.
Zoom lens - A zoom lens is a mechanical assembly of lenses whose focal length can be changed, as opposed to a prime lens, which has a fixed focal length. They are commonly used with still and video cameras, some binoculars and telescopes, and other optical instruments.
Canon EF 28-135mm lens - The Canon EF 28-135mm lens is a standard zoom lens with image stabilization (IS) technology and a high zoom ratio made by Canon. The lens is based on the EF Lens Mount and will work with all film and digital EOS cameras that support this mount.
Prime lens - In film and photography, a prime lens is a photographic lens whose focal length is fixed, as opposed to a zoom lens, which has a variable focal length. Prime lenses are not as versatile as their zoom counterparts, but are often of superior optical quality and lower cost.

Amateur astronomy Amateur astronomy and scientific research Unlike professional astronomy, scientific research Unlike professional astronomy, scientific research is not typically the main goal for most amateur astronomers. Astronomy is often promoted as one of the Moon. In the past and present, amateur astronomers also operate during the day for events such as monitoring the brightness changes of variable stars, helping to track asteroids, and observing occultations to determine both the shape of asteroids and the shape of asteroids and the shape of asteroids and the shape of asteroids and the shape of the Moon. In the past and present, amateur astronomers also operate during the day for events such as monitoring the brightness changes of variable stars, helping to track asteroids, and observing occultations to determine both the shape of the few remaining sciences for which amateurs can still contribute useful data. Work of scientific merit is certainly possible, however, and many amateurs contribute to the knowledge base of professional astronomers very succesfully. It is usually associated with viewing the night sky when most celestial objects and events are visible, but sometimes amateur astronomers also operate during the day for events such as monitoring the brightness changes of variable stars, helping to track asteroids, and observing occultations to determine both the shape of the Moon.
