I'm a Sony Z7 owner and it's coming up to two years since its purchase. I'm a wedding videographer so I know for a fact I've carried out about 20 or so weddings to date at an average of three hours of recording per wedding, plus other freelance activities which probably near equal this.

However, my hours meter is as follows:

Operation: 2x10H
Drum Run: 1x10H
Tape Run: 0x10H
Threading: 75x10

Now the only one that seems realistic is the threading, but I know for a fact that I've recorded way more than 10 hours worth of footage. Is there any explanation for these low figures?

You need to have Sony upgrade the firmware. This is an issue with early releases of the z7u. Mine has the same problem.

Here's a link to the US Sony HDV micro site describing the issue:
