As MiniDV tapes are getting expensive and hard to find, I'm looking harder and harder at replacing my SD Pannys with K-5s. Most of my clients are still happy with my SD productions, so I haven't been in a hurry to go all HD yet. There certainly are several factors in this decision, but as I was doing a little research and found a spec that has be a bit concerned. Under the K-5 power specs, it lists the max video record time as "Aprox 25 min (automatic overheat shutdown protection)." HUH?!? Video record time is limited by an overheat condition?!? Does the battery overheat? The sensor? Video processor? I often produce lecture vids that exceed 2 hours, and many weddings can push 25-35 minutes JUST for the ceremony, a 25 minute record time isn't gonna cut it! Now, if battery heat is the issue, I'd be plugged into the wall for anything even close to that long, so it's a non-issue. Any other scenario, however, means I'd be dropping over $1500 (x3) on a tool that simply won't do the job. Anyone out there made any lengthy vids with a K-5 yet, or am I going to be the guinea pig?
