I read a comment about the A6000 on B&H's website and @BradZChef (commentor) said the maximum video length of Sony A6000 is just 30 minutes. I took a look at the Sony A6000 specifications BUT I didn't find any information mentioning limited video length on the A6000. I also googled for it but I didn't find any resources. Anyone have any idea? Thanks!
Page 36 of the manual.
The table below shows the approximate maximum recording times. These are the total times for all movie files. Continuous shooting is possible for approximately 29 minutes (a product specification limit). The maximum continuous recording time of an MP4 (12M) format movie is about 20 minutes (limited by the 2 GB file size restriction).
More generally, you'll find that most cameras which are primarily stills cameras will be limited to 30 minutes of video. This is due to EU regulations which mean that anything which can record longer than 30 minutes is a "video camera" and attracts a higher rate of duty. Panasonic are a notable exception to this in that they produce separate EU and non-EU models, with only the EU model being limited.
