Canon has unveiled the EOS 500D (Digital Rebel T1i), the latest addition to its compact DSLR series. The upper-entry-level camera features a 15.1 MP APS-C CMOS sensor with 1080p HD video recording at 20fps. It also offers a 3.0 inch LCD with 920,000 dot resolution and an ISO sensitivity range expandable up to 12800 equivalent. It includes a faster Digic 4 processor offering better noise reduction at higher ISO's and continuous shooting speeds of up to 3.4 fps delivering 170 large JPEG images in a single burst.



Now at the top of the Rebel line, the Canon T1i takes on the Nikon D90, with its video mode, while the XS and XSi are left to challenge the Nikon D40 and D60. With the Rebel T1i, Canon is answering the pincer move that Nikon's put on it in the past few years, now matching them model-to-model at the low end, because the XS and XSi will remain in the lineup.

Movie mode comes to the Rebel T1i with quite similar capabilities to the Canon 5D Mark II, though it's highest complete HD resolution is 720p at 30fps. It can capture 1080p videos, but only at 20fps, which isn't technically fully up to spec. Standard 640x480 movies are also available at 30fps. You can manually focus or autofocus via contrast detect by pressing the Canon T1i's rear AE/AF-Lock button.

With the combination of its 15.1-megapixel APS-C size CMOS image sensor and the powerful new DIGIC 4 image processor, the Canon EOS Rebel T1i camera provides ISO speeds from ISO 100 up to ISO 3200 in whole stop increments, along with two additional high-speed ISO settings - H1: 6400 and H2: 12800. The Canon EOS T1i Digital SLR utilizes a precise nine-point Autofocus (AF) system and AF sensor for enhanced subject detection. The new Canon EOS Rebel T1i DSLR provides a cross-type AF measurement at the center that is effective with all EF and EF-S lenses, while providing enhanced precision with lenses having maximum apertures of f/2.8 or faster. The cross-type AF measurement reads a wider variety of subject matter than conventional single-axis AF sensors and thus increases the new camera's ability to autofocus quickly and accurately when shooting still images.

Also introduced at the same time is the very small Speedlite 270EX, a new flash that is easy to pocket and gives cameras like the Rebel T1i and the PowerShot G10 an accessory flash that won't threaten to flip these lightweight cameras over. The flash head zooms manually from 28mm to 50mm coverage, and flips up to 90 degrees. Like other EX Speedlites, the 270EX transmits color temperature information to the camera. Power comes from two AA batteries.
