Poor quality
2004-11-26Very poor quality lens. Came with a Rebel kit. Inoperable after a year of ownership. $120 repair estimate -- more than the new cost. I recommend you avoid this lens.
not bad.... but you should consider paying a little more
2003-08-16I, like most people, got this lens when buying a kit. Unlike one review, I found this lens to have excellent optics. While not quite like a Nikon lens, the quality of pictures the lens produces is more than enough for most users. For the past 4 years, I have thouroughly enjoyed using it. Unfortunately, something is not ligning up on the connections between the lens and the camera body and the camera is unable to read/set the aperture on the lens, therebye making it impossible to take pictures. I have used other lenses on the body, and they work fine, so I'm assuming it is a problem with the lens. Consider paying a little more when buying a lens... in the long run, it might save you money.
Buy this lens!
2003-01-20I have a 20x30 poster of some cliffs in Ireland hanging in my living room because the picture quality was too great to not enlarge! This lens gives you great versitility and the quality is great for the average person.
A wonderful, inexpensive lens - a must-have for EOS users
2001-03-27This entry level canon lens is an optical marvel that will enable anyone to shoot professional-quality photographs. The 28-80 mm zoom range is among the most useful for everything from vast landscapes at 28 mm to intimate portraits at 80 mm. The aperture of the lens allows hand-held shooting in most situations. The quality of the lens is remarkable for the price. Every EOS user should have this lens in his/her bag!

Core 2 Duo Scaling
Laptop Scaling
Intel's Core 2 Duo is easily the best mobile processor on the market today, boasting sky-high performance and low power consumption. But which CPU is for you: the super expensive T7600, the bargain-priced T5500, or something in between?
This article will first take a look at the various versions of Core 2 Duo that Intel has to offer. We will compare Core 2 Duo clocked at four speed grades: 2.33GHz, 2.16GHz, 2GHz, and 1.83GHz in a variety of benchmarks and let you know how to get your best bang for the buck.
Note: We will refer to a Core 2 Duo “T7000�multiple times in this article. We were unable to get a Merom sample with 2MB L2 cache, thus we lowered the clock speed of our 4MB L2 model to 1.83GHz to perform near that of the T5600 (1.83GHz, 2MB L2 cache), resulting in our unofficial “T7000�nomenclature.
The Core 2 Duo Processor
Intel has two lines of Core 2 Duo processors: notebook and desktop. Core 2 Duo for notebooks is codenamed Merom, while Core ...
Camera basics: shutter-speed, aperture and ISO
In this article, I’ll introduce you to the basic elements that you can use to control exposure in your shooting. If you have a digital SLR, there will be a way to set all of these controls on your camera, but since they differ between manufacturers and models, you’ll need to refer to your camera’s manual to find out exactly how to change them.
All cameras, whether an ancient film camera, or a more modern digital, work in pretty much the same way. Photographs are taken by letting light fall onto a light-sensitive medium, which records the image. Traditionally, this has been film, but more recently, it tends to be a digital sensor. The more light that falls onto the film or sensor, the lighter the image.
Put simply, a camera consists of a light-tight box that stores a light-sensitive device (either a film or a digital sensor), a lens that magnifies and focuses the image onto that light-sensitive device through a hole in the box (called the aperture) , and a shutter that opens ...
