APS-C sensors? Being new to photography, I don't know what a APS-C means and am concerned about compatibility with my Canon Rebel xs. The manual for the Rebel states that it has a CMOS sensor. But when I checked the Tamron website and the list of cameras compatible with this lens it does list the Rebel xs. Any help decoding the lingo would be appreciated as I'd hate to make an expensive mistake.
All of the Canon Rebel series, and also the 30D, 40D, 50D, and 60D series are APS-C sensor cameras, as is the 7D, meaning that their sensors are smaller than a full-frame camera's. Some lenses, like this one, and the Canon EF-S lenses, are designed specifically for the smaller APS-C sensor and can't be used on a full-frame camera. This should be a fine all-around lens if you don't plan on upgrading to a full-frame camera anytime soon ( there are so many great APS-C cameras that you'd probably only go full-frame if you were also going pro). HOpe this is helpful.
