Ok to keep mirror up on a 5DMk4?

  1. 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?
  2. the only possible downside I can think of is that the sensor may get hot after a while leading to more noise potentially. Probably not an issue in cold climate.
  3. Be sure that the sun does not enter the field of view or sensor damage may result.
  4. Thanks. Good tip about the sun.
    Happy New Year.
