This varies quite a lot. My Sony A7RII has a time limit of 30 minutes which can be hacked (https://petapixel.com/2016/04/25/hacker-cracks-video-limit-language-menu-sony-alpha-cameras/ https://petapixel.com/2016/04/25/hacker-cracks-video-limit-l...) while my Panasonic GH5 has no limit at all (though I use a Ninja Shogun anyway). And I think one reason it isn't reviewed in much depth is that DSLR shooters are likely to do one of the following: - Use a dedicated video camera rather than an SLR. - Not care about a 30 minute time limit, how often do you need 30 minutes of continuous video? - Use an external recorder like a Ninja Assassin, which doesn't have a time limit.
