One of the great new features on the Canon 7D Mark II is the ability to shoot timelapse photos without the need for the overpriced Canon TC-80N3, which was required on prior Canon pro and prosumer DSLRs if you wanted to shoot in interval mode.
However, when the Canon 7D Mark II was initially announced, there was some confusion about its timelapse capabilities because some of the initial specs and documentation referenced that it could be programmed to capture photos in intervals between 1 and 99 images. That would suck and be pretty much a pointless feature since a second of video footage from a timelapse would contain at least 24 images (e.g., 1080p video at 24fps).
The 7D Mark II can, in fact, capture an unlimited number of shots. Of course, the number of shots is limited by battery life and memory card storage. You should be able to push it to several thousand images though. You can set intervals from 1 second up to several hours. Check out the video above for a walkthrough of the menu settings to enable interval capture on the 7D Mark II.
