I'm experimenting with changing my shooting technique using tripod-mounted cameras, from triggering using mirror lock-up to just using live view.
I recall warnings about huge build-up of sensor noise from using a precursor of live view on the early CCD backs from Sinar. They even promoted these with some sort of cooling features built in to the backs. Of course this is 10+ years back, and before more successful CMOS-based sensors. Nobody seems to be talking about sensor noise that way these days, but still I wonder, so here's a question for the collective wisdom here:
Does anyone have knowledge about any increased noise side effects from using live view shooting this way? I can easily spend several minutes composing, etc. and exposing one shot or sequence, then repeat a number of times over a couple hours. So it can add up to a significant amount of time with the sensor "active"; if the ambient temperature is pretty hot as well - can these effects add up to a significant influence on the sensor's behavior? (e.g., increased noise) Or is this issue moot with current CMOS technology like that in a Canon 5D Mk IV, or Pentax 654z)?
Thanks,
John
