I was trying live view and have been told that prolonged use ( more than a few minutes ?) will produce noise in the image . Disappointing for me as I had great visions of using it a lot .

Looking in my camera manual (D850) it does say that an overheating warning is given before the camera automatically shuts down because of the overheating .

Before I try to find the time to do some tests I wondered if any one had any experience of this .

I have observed this in 5D-II, 6D, D610 and D750.
More than the briefest use of live view will provoke
hot pixels. However, even when thehot pixels have
shown up, I'm not getting a generalized increase in
noise. This seems to be an SLR plague, as if SLRs
are not designed for heavy LV use, as opposed to
my full time LV cameras which apparently take the
problem into account in their design, and do not
have this ailment. Clearly, LV cameras would not
be taking over the market if it were otherwise.

Hot pixels appear almost exclusively at high ISO
settings. If you stick to 100 thru about 400 you'll
prolly never see them in your images but they're
lurking, Just spin up the ISO and voila !

You can remap the sensor and the hot pixels will
recede but when LV use provokes them again it
will be the very same pixels. They're not random
so they must be tiny flaws in the sensor.

I realize that some SLRs are used as camcorders.
Video is at lower MP than stills. Maybe thaz how
SLR videos are not peppered with hot pixels but
I'm really guessing .....
