Thanks - very helpful.
I think I'm going to write the 70-X off and look at the sort of options you suggest.

I received a reply from Pentax, who said "E7", an error code, indicates a shutter function error, and requires a technician's inspection.

Has anyone any advice as to the best way to have this looked at, and what the likely cost might be. I live in the Blackpool (Lancs) area.

Thanks.

This is my first visit and my first post, so apologies if this a question which crops up regularly, but my Zoom 70-X is giving an 'E7' message when trying to take a picture, which doesn't seem to be referenced in the manual.

Id be grateful if anyone can advise what the problem is and the potential solution(s).

Many Thanks.
