Hi, I am looking for a replacement for my pocket Panasonic DMC-TZ3 which is over three years old.. I have been fairly pleased with this camera for outdoor shots, but inside it has not been great. When the flash is used the pictures are usually over exposed. I also now have a 2 year old, so I'm looking for something that has a very fast autofocus, and a short time lag between pressing the button and the picture being taken. I rarely use the 10x zoom function, but the Wide Angle (28mm eq) is important. Would be happy to spend around 150-200. Any advice please?
