I pretty much just broke my S5000 Z the other day when I spilled some coffee etc.. I can still use the camera (hair dryer+ let to dry for a few days) and all the buttons on it are now a bit harder to push etc, but I'm still considering an upgrade. I'm looking at either the S7000Z or the S5500Z or the S20 Pro. Which of these cameras is better? I use the camera mostly for taking photos of cars in action (drift etc) at a track. I am usually taking photos from the sidelines so I require a decent zoom. I have a 2X teleconversion lens(58mm to 62mm thread) and and a Polariser filter (55mm thread) and I use a adapter ring to fit the conversion lens to the camera. All the above cameras can fit my lens extensions on. Which camera should I go for? I know the S20 Pro and S7000 have not got as much zoom as the S5500, but the S5500 has only 4MP as opposed to 6MP.
