Hey I want to shoot PHOTO only timelapse with interval 1 second..

The only option I see right now is *Photo + Video* and it only allows 2 second interval..

I don't want a 720p timelapse.. I want to take the 4k resolution pictures and turn them into a timelapse on my computer!

Is it possible yet? New firmware update soon?!?!?1

Well, right now timelapse is not available for 4K video, however it depends on how long you want your timelapse to be. If its just a short one, you can try to do it manually like in old times
However it's not the best way! I've already passed the idea of making 4K timelapse available in future to our RD guys, hope they can do something about it
