Hi, I and considering to purchase a Sony Cyber shot.. But I'm confused as which I should go for... The Sony Cybershot TX9 or the The Sony Cybershot WX5. the main difference seems to be the lens. So could any1 tell me the diff between the 2 lenses and which one is better in quality? (did some research and seems the G lens is used in SLRs.. Isnt that good?) Thanks
