Basic Information About Canon Zoom Lenses
Canon is a multinational company that mainly manufactures products related to imaging like cameras, photocopiers, camcorders, computer printers and steppers. The Canon Company is origin of Japan. The headquarters of Canon is situated in Ota, Tokyo, Japan.
A zoom lens is an assembly of many types of lens. With a zoom lens the focal length can be varied in a camera or camcorder. It is also used in projectors, binoculars, microscopes, telescopes and many other optical instruments. A good zoom lens maintains the focus automatically at the time of the changing of focal length.
Canon is an imaging company that is specialized in producing of zoom lenses. Canon and Nikon are the top two companies that make zoom lenses for the most of the world. Canon has more market share in zoom lens than Nikon. Canon makes various kinds of zoom lenses vary in the focal length. Canon makes seven types of focal length changing zoom lenses. Each of them is specialized for their work. The most of the lenses are from the finest series of Canon lenses, the L series. It gives the user a more critical sharp end image with brighter resolutions. The user may never sense the changes of the focal lengths if he is using a Canon zoom lens. The Canon zoom lenses greatly utilize the well-known ED and many fluorite elements. They also use spherical glass designs on the lenses. These things make the lenses costly to buy because all of the elements are high in price. The price is high, and so people cannot decide about buying the Canon zoom lenses. They think that is it really necessary to buy such an expensive zoom lens? Is it really works better than the other cheap zoom lenses that are found in the market? The answer is yes. The ED and the Fluorite elements may not give difference on small size photos, but when you will zoom the pictures then the difference can be seen. The higher resolution that is given by the zoom lenses makes it brighter, shinier and sharp. Canon has a broader list of high end lenses than Nikon or other companies. That is why it serves well for all.

Orion Explorer II 7-21mm Zoom Telescope Eyepiece $79.99 Now even the casual telescope user can enjoy the benefits of zoom eyepiece technology. A twist of the affordable Explorer II Zoom housing changes the focal length from 21mm to 7mm, or to any focal length in between. That makes it ideal for locating an object at low magnification, then zooming in at higher magnifications for closer inspection. Without changing eyepieces! Actual magnification range will depend on the focal length of your telescope. It works equally well for astronomical or terrestrial viewing. This four-lens eyepiece boasts fully coated optics and exceptionally long eye relief ranging from 33mm to 16mm. Apparent field of view is 30-deg at 21mm and 43-deg at 7mm. Rubber traction ring ensures a good grip. The 1.25″ barrel is threaded for filters. A nice value in a quality zoom eyepiece! |

Orion StarMax 90 Mak-Cass Telescope & Make It Zoom Kit $399.99 Whoever coined the phrase “big things come in small packages”, would have definitely applied that expression to our new StarMax 90 TableTop. This ultra-compact Mak-Cass gives surprisingly big views for an instrument of its modest size, making it an elegant first telescope or a great grab-and-go second telescope! The long, 1250mm (f/13.8) focal length gives the StarMax 90 TableTop some serious magnifying power – the included 25mm and 10mm 1.25-inch Super 3-element eyepieces yield powers of 50x and 125x, respectively. It collects over 25% more light than its GoScope 80 cousin, and up to 225% more light than a 60mm refractor telescope. So you’ll be able to enjoy planetary delights such as lunar landscapes, Saturn’s rings and Jupiter’s moons. As you scan the Milky Way, you’ll also be able to pull in some open and globular star clusters, as well as a nebula or two. The tube assembly of the StarMax 90mm TableTop Telescope is attached to a stable swivel base, via a quick-release dovetail mount with adjustable altitude tension. The tube can easily be removed from the base and mounted on an optional photo tripod. The small swivel base itself can also be mounted on a camera tripod with a 3/8-inch screw. A red-dot view finder, internal focuser (which moves the primary lens back and forth) and included 90-degree star diagonal round out the features of this compact, yet surprisingly capable, Mak Cass telescope. |
