I'm thinking of buying a Contax t3 this weekend and am wondering how reliable of a camera this is today. Might one expect 5 years of life out of this used camera? Are there better models of pocket cameras worth considering? One other option is a Fuji Natura. I am not sure how well this compares to the Contax but I do know that it is pretty small. I want something I can have in my pocket at all times. Thanks!
