Removing Recording Time Limit on LX100

One of the rare things annoying me on my Panasonic LX100 is recording time limit. No matter how big SD you have, there is only 30 minutes you can record in one go. Yes, this is more than enough 99% of the time, but there are scenarios this disables, for example recording my occasional talk.

Well, reading through some DP Review forum threads I noticed discussion about service mode for the purpose of PAL/NTSC mode switcheroo and I wondered whether service mode offers anything else.

Well, to try it out, I followed instructions from the thread. First I kept Right, Display, and AE/AF Lock buttons while turning on the camera. Once camera has been turned on, I released all those buttons and swiched into Playback. Then I held Up and AE/AF Lock buttons while turning off the camera. If done correctly (and it took me a few tries), camera will flash yellow rectangle at you. Welcome to the service mode!

While in service mode, I suddenly got some limits increased:

AVCHDFHD 24M 24p29m 59s2h 55m ⬆5h 52m ⬆

As you can see, camera can now record MP4 in 4K limited only by card size and all AVCHD modes got a bump in recording length. Strangely, the same improvement is not visible in other MP4 modes as they all either retained their 30 minute or lower limits.

In case you find exclamation mark annoying, you can always exit service mode by setting both shutter speed and aperture to A. Then press Menu and Right key together and turn off the camera. That will present you with a strange menu where pressing Right, Right will end the service mode. Unfortunately that comes at the cost of your settings as that’ll do factory reset.

Me? I’m gonna keep my service mode on.
