Digital DNA

Unless you’re already committed to a specific brand through years of lens and accessory purchases, buying a new DSLR today may mean comparing a dozen models.

Canon EOS Rebel T2i

Canon's entry-level DSLRs have been popular from the introduction of the original EOS Digital Rebel in 2003—the first DSLR to sell for under $1,000. Today, you can purchase a number of DSLRs for under $1,000, and the newest Rebel, the T2i, is among the best. It features an 18-megapixel sensor like the 7D and 60D, a DIGIC 4 processor and full HD video. It also features the 63-zone dual-layer metering system introduced in the 7D and the 9-point AF system used in the 50D.

CANON LENSES

Canon offers an extensive array of lenses for its DSLRs. The APS-C models can use all of them; the larger-sensor cameras can't use the EF-S lenses, which were designed specifically for the smaller sensors.


There are more than 60 lenses in the lineup, from an 8-15mm fisheye zoom to an 800mm ƒ/5.6 supertelephoto, including more than 20 with built-in image stabilizers (these are designated "IS"). Four manual-focus TS-E lenses provide tilt-shift capability. There are also 1.4x and 2x teleconverters.

CANON ACCESSORIES

Canon offers an extensive array of lenses for its DSLRs. The APS-C models can use all of them; the larger-sensor cameras can't use the EF-S lenses, which were designed specifically for the smaller sensors.


Accessories for the EOS DSLRs include flash units (pro through economy-level, plus macro twin and ringlight), remote controls, angle finders, battery grips and wireless file transmitters, handy for photojournalists. The battery grips hold one or two standard lithium-ion batteries to extend shooting capacity and permit shooting with AA batteries. The grips also provide controls for easier vertical-format shooting and added bulk that provides better balance when using long lenses./td>
