The autofocus locks onto the subject faster, and Eye Detection is improved so it recognizes the eyes and face further away. Eye Detection can now even be used during video with Movie Servo AF, and you can use both Eye and Face Detection during Servo AF.
I am not experienced with cameras (in fact this is my first one) but this one has been fairly easy to get to know. With a little trial and error you can get some nice clear photos. Also the camera arrived in great condition, I could hardly tell that it was used so that was also quite nice. Overall I like getting to know how to use this product, and have already had some good results.
Compact yet solid build. Has a professional camera feel to it, even though I was used to the DSLR weight/feel, this compact format has not been an inconvenience in shooting, but rather a big step up - I can take it anywhere with me, (hiking etc). The buttons are small but I have no problem using them, actually very convenient as they are in close proximity. If you are already used to the Canon DSLRs, this will be a delight, if you are a beginner the touchscreen menus are SUPER EASY and have plenty of helping tips showing up to guide. To my surprise the kit lens is pretty good - better than I expected, with a very useful working range.
