Please help me get back my F710
I fear you are basically out of luck. The F710 was a decent camera but very prone to the dreaded lens error issue. Actually it was easily fixable but people either sent them to Fuji for repair or junked them. I think Fuji must have thrown their stash out as well as I never see them on the used market. If you really liked it try a used F20 or go to ebay and try for one of the 800 series.
