I used the Q to take a time lapse of a neighborhood movie night we put on tonight.
I wanted to see how long a single battery would hold out.
The stats were:
Fully charged Pentax OEM battery
Lasted for 856 exposures
Total time from start to finish was 143 minutes (2 hours 23 minutes)
Interval setting was a every 10 seconds
The lens used was 03 Fisheye which has a fixed aperture of f5.6
I used AV mode with Auto ISO max of 3200
Starting at 6:40 PM the camera chose ISO 250, exposure of 1/125 sec
By end of the evening the camera used ISO 3200, exposure of 2 seconds (the max it will do with toy lens)
If I was to do it again I would have set a lower max ISO as the ISO 3200 shots are noisy and I would have liked a darker scene at the end.
I could have PP'd with noise reduction but did not bother for this experiment.
I was surprised the battery lasted as long as it did. In interval mode the camera shuts off quickly after each picture which saves power.
If I do this again I will use the power adapter so I can get the wrap up of the event.
I mounted the camera on the window of my truck that was parked at the curb, using a Manfrotto 243 window mount.
I used Windows Live Movie Maker to join the shots, using a duration of .25 seconds for each.
