One of the advantages of going with a Canon EOS SLR digital camera is that you can adapt it with over 50 different kinds of lenses. So what are some interesting lenses which you can employ to heighten your camera's sensitivity, speed, focus, and image quality? In the cheaper range, you can get plastic attachments. These are easy to mount, but frankly don't provide much of an advantage as far as focusing is concerned. Great lenses are available for a few hundred dollars. You can get the EF-S short back focus 18 by 55 mm lens to supplement the capacities of your EOS Canon Digital Rebel or 10-D. While the normal EF lens offers a number of ways to manipulate image sharpness, the short back focus element is set nearer to the camera's image sensor for an even lighter touch. Of course, EF-S lenses are at present only compatible with the Digital Rebel and the Digital Rebel XT. For a great wide-angle lens that won't cost you an arm and a leg, consider the DS 20 by 35 mm IS USM. You get a distant scale, silent operation, and steady performance. You can also adapt this unit to Canon film cameras, such as the EOS 35mm. Consider whether you want to get image stabilization (IS) in your lens. This fresh technology employs gyroscopic action to eliminate the potential for hand tremors to influence image quality. Whisper quiet, optimized, and useful in a variety of circumstances, IS technology will certainly add a little bit to the price tag of your lens, but may be very worth the cost. |
