Gerry Whitmarsh Posted January 1, 2018 Share Posted January 1, 2018 Hi, I have just bought a 5DMk4. I was thinking of focusing, for example, on a bird feeder and using the Canon connect app on my smart phone and live view to wait until a suitable moment to shoot. I was wondering if there were any adverse effects to keeping the mirror up for long periods of time, apart from battery drain of course. I know that with previous models it was not recommended but with modern cameras is it an issue? Link to comment Share on other sites More sharing options...

Probably not an issue in cold climate. Link to comment Share on other sites More sharing options...
Glenn McCreery Posted January 2, 2018 Share Posted January 2, 2018 Be sure that the sun does not enter the field of view or sensor damage may result. Link to comment Share on other sites More sharing options...
