I bought this camera for my girlfriend. I tested up and down and I have to say that the rendering is stunning! The device is very compact and well built. The sharpness of the image is very good as it does not exceed 800. While Iso 800 it starts a little whitecaps when there is little light, but all the same, the quality is at the rendezvous . The automatic modes are very well made and are perfect for the uninitiated. Pv and Tv modes are present for finer adjustments. I can not yet say with respect to autonomy but it seems well beyond the 220-250 photos with a moderate use of flash and with the GPS turned off. As an aside, the flash function gadget is pretty and you can use it only sporadically, for example 1 picture to see where we are. As a user seasoned DSLR, I must admit that this compact is very good, especially considering its price. Beware though, you must return the papers to Canon within 15 days of sending the order to be reimbursed
