A7RII hot pixels?

Those likely aren\'t stuck pixels - they\'re just hot pixels from the long exposure. You can tell for sure by forcing a stuck pixel remapping cycle, which previous A7-series models do automatically I think every 30 days. To force the cycle, set the camera\'s clock a few months forward then power the camera off. When you do you should hear some loudish shutter noises - that\'s the camera performing a remapping cycle.



Although I understand what you\'re saying, the D810 were not stuck pixel. A stuck pixel theoretically would be on all the time, regardless of length of exposure. Nikon had a fix for it, why doesn\'t Sony? Here\'s a link about the D810 thermal noise issue:
