I need to know if the Canon T2i has the same battery as the T1i. I am borrowing a T1i from a friend and I won't be able to get the camera until the day I need it. I have a T2i and I have a power cord (that plugs into the wall) and several spare batteries. Will the batteries from the T2i fit the T1i?
The Canon T2i actually uses a newer battery pack - the LP-E8 as opposed to the T1i that used the LP-E5. The LP-E8 has better battery performance, but unfortunately you cannot use them interchangeably.
