I recently purchased an F3HP and did some research on the serial number. The serial number on my F3HP begins with 123 but my research indicates that the F3HP series began with 140. According to this info, my F3HP was actually one of the first production regular F3 bodies, not from the F3HP series. It was sold to me as an F3HP in EX condition. The body and prism look pretty decent. Was I "taken for a ride" and sold an old F3 nice looking body with a newer HP prism? Should I contact the store I purchased it from and tell them my concern/exchange for a true F3HP? My concern is that although the body and prism look good, I fear that the electronics and LCD panels will not last as long as they would if I had been given a true F3HP with the appropriate serial number starting with 140 or above. I have purchased from this store in the past and have not had this sort of problem. This does shake my confidence in them somewhat. Any suggestions?
