Canon's CMOS (complementary metal oxide semiconductor) sensor captures images with exceptional clarity and tonal range and offers the most pixels in its class. It offers many of the same new technologies as used by Canon's professional cameras to maximize each pixel's light gathering efficiency.
With the EOS Rebel T1i, analog to digital signal conversion is executed by a 14-bit processor, which generates digital data with incredibly smooth tones. A feature that originally appeared in top-of-the-line pro digital SLR cameras, the 14-bit conversion gives incredibly smooth transitions from light to dark colors with far less risk of "banding." A sky at sunset is a perfect example. With this rich 14-bit gradation, the EOS Rebel T1i offers RAW images of the highest quality that can be processed with Canon's Digital Photo Professional software. Even JPEG files, which are always finished at 8-bits per channel, use the full 14-bit conversion initially to generate the best possible color and tonal detail.
The Canon EF-S 18-135mm f/3.5-5.6 IS Lens boasts a 35mm equivalency of 29-216mm when used with a Canon APS-C EOS Digital SLR. Measuring just 4" in length and weighing about a pound, the lens offers a convenient wide angle to telephoto focal length.
