I want to buy a Sony Cybershot 15 mega pixel camera for me. It should have a very high optical and normal digital zoom. Dsc-w120 is the model that I am looking but I do not know whether it has all the requirement that I am looking for or not. So, try to tell me its requirement and the most important thing the best Sony store to buy it in whole New York. If there is another better model which is suitable as per my requirement, tell me that one also.
