90d Interval timer

Been using my 90d for some time and like most of the tools built into the camera. Started to get into timelapse creation and noticed quite a bit of difference between the movie mode timelapse creation and the interval timer in normal shooting mode.

 

Not sure where or to whom to reach out to for a feature request so starting here. Would it be possible to make the normal shooting mode interval timer work more like the movie mode one? For instance keeping the mirror locked up, staying in a low power state, and being able to go higher than 99 exposures before going to unlimited. Supprisingly the interval timer does not work while mirror lockup is enabled. I am wanting to process the pictures in an external program to be able to edit the shots.

Re: 90d Interval timer

It is a bit awkward but you can accomplish part of what you want by using the TC-80N3 with the camera's built in delay timer to let you use mirror lockup when the time exceeds 30 seconds between exposures.  The camera will drop the mirror after 30 seconds of standby to avoid battery drain so you set the external intervalometer to provide the desired time between exposures and your camera to delay mode.  When the TC-80N3 tells your shutter to fire, your camera should raise its mirror to the locked position and take the photo.  You are still limited to either 1-99 or unlimited in the number of timed shots using the external controller.

Don't you need two presses on the shutter to take a photo during mirror lockup?  The first press is to raise the mirror, and then a second press to fire the shutter, which also drops the mirror.

Re: 90d Interval timer

Not sure it works with every Canon model but using the TC80-N3 in combination with the camera's built in delay timer causes the mirror to raise when the camera is triggered by the signal from the TC80-N3 and then the camera actually fires its shutter after its own self timer runs.  This gets around the 2 push issue when mirror lockup times out between activations.

Interesting trick.
