I am wondering just how critical you find the 180 degree shutter rule is when travelling. The reason I ask is that, while I do have a variable ND filter, I am simply a hobbyist and do a lot of still image shots when travelling. Constantly using a variable ND filter and adjusting it, and making sure I am following the 180 degree shutter rule is simply too much of a pain in the ***, especially when you want to film those "candid" moments and not piss off the significant other by playing around with the camera. Also, I enjoy just being able to use the depth of field I want without adjusting everything for each clip I film. In summary: do you find the 180 degree shutter rule still critical for video quality when the output is simply travel videos? They won't quite be your average "home-made" video, but rather a good quality travel video.
