What is the difference between these two canon cameras?
Sunday, April 26th, 2009Canon PowerShot A550 7.1MP Digital Camera with 4x Optical Zoom
Canon PowerShot A570IS 7.1MP Digital Camera with 4x Optical Image Stabilized Zoom
they both have 7.1mp and 4x optical zoom except the a570 has image stabilized zoom so is that the only difference? i’m trying to figure out if that’s the only thing because that one is $20 more.
thanks!
