Having used both the Sony and GoPro over our Hokkaido trip, I now have some more thoughts on these two cameras and how they stack up against each other. GoPro feature set wise wins. Their WiFi remote is very useful, much more than linking up a smartphone. How often in -10C with winds blasting enough to almost knock you over and snow swirling in your face are you going to dig out your smartphone, take off your gloves in order to use the phone, wait for the app to sync, then browse through it to change settings or start the camera. The GoPro allows full access to all functions while in the waterproof case, although in use the only setting I changed in the field was the inverted setting. The Sony once it was in case only has the start/stop button, which ended up being fine. And it’s a nice big button that makes it glove friendly.
But the Sony has only one tiny impossible to see record indicator LED on the back, I could never see it in the field. The start tone is too soft, again impossible to hear through layers of neckwarmer, helmet ear muff, blasting snow and wind.
