Hi , I use a Canon S95 now , but it is slow to focus , high iso ot good ......DOF is always BIG ... So i was looking to upgrade. Mu4/3 looks good , but Fuji seems even better . I don't have a bucket of money to spend , so i would rather look out for a good secondhand camera for a good price. I see X10.X20 are the cheapest , but with fixed lens . X-a1 is next , X-E1 and X100(s) .... I have four kids , cats , flowers , and i go fishing . Which secondhand Fuji can be had cheap now and would give me the best bang for the money ?
