thanks for your opinion. what you said it's true. Seems to be that the e18 error is not at common in the s1 as in the older models. I found two more with the same problem here though:
Im still considering the S1 though, however it is scary how fragil (I guess) the lense is and that for a small mistake you are going to get the e18 forever.
Im also considering the fuji 5100 and the minolta z3.
