> The T3 has a slghtly wider lens. It has a wider range of slow and fast shutter sppeds, which may or may not be important to you. It has a most sophisticated AF system than the T2, which again may or may not be important for you. The T3 lacks the manual focus override with rangefinder system which is uniquie to the T2 upon PnS cameras.
If you just want to point and shoot, then the T3 is a more flexible camera. If you like to assert manual control for creative purposes, the T2 seems more practical. The manual override functions of the T3 are less useful and not too practical in real-world use.
As to lens comparison, I would expect the T3 to be better because uit's newer, but from what little I've seen on the subject, the T2 may be a better all-around performer in regular use, having a very consistent performance across the image frame and at various aperatures. Unhappily, the lens comparison republished in PDF on this site was done at such low resolution that it's unreadable.
