More power to you: EOS Rebel Ti's 300V battery pack (street price, about $35) has vertical shutter release and loads with four AA alkaline energizers or rechargeable nickel-hydride batteries. (You can't use AA lithiums, darn it!)
Flash control remains as it was in the Rebel 2000 with the built-in pop-up using three-zone TTL flash metering around the center AFpoint. With an Ex-series Canon Speedlite, E-TTL metering centers on the bright areas of the 35-zone metering sensor.
At a kit street price (including lens) of about $350, Canon hopes the attraction of the 28-90mm lens (instead of the 28-80mm lens on rival kits) will continue to drive consumers Rebelwards. But the Rebel Ti will still have a very attractive, low-priced, feature-laden group of pack rivals nipping at its heels, with Nikon and Minolta kits costing $50 and $75 less than the Rebel Ti, but with 28-80mm lenses.
The Ti will be available body only, for about $240. A date quartz back model will be about $260.
Other versions of the Ti are in the planning stages for the future, and at least one kit with the 28-90mm USM lens in place of the current EF lens.
While a critical comparison of the Rebel Ti and other-brand rivals would be fun for me to write (and I promise I shall do it), such will take time, but the time was now to give you a quickie report on the early production Rebel Ti.
In the meantime, my admiration for the Rebel Ti's beauty is great. Time and tests will tell whether beauty is only skin deep.
