Newbie DSLR Question

[mikemaps]

Sorry if this question has been asked before, but I could't find an answer. I'm shooting with an Canon 80D, but my question is general. I focus using Live View, but should I shoot in Live View? Seems I remember seeing something that said the sensor gets hotter in Live View & you shouldn't shoot in Live View. Also, should i enable Mirror Lockup? Opinions would be appreciated.

No, for the reasons you cite:)

Mirror Lockup?

I think that with long exposures, it's not necessary. I don't see any difference with or without. Just one more thing to go wrong in the dark!

Just my €0.02

As already said use liveview to focus then shoot subs in normal, I sometimes do this all over the inbuilt wi fi link but then switch to a Pluto trigger to take the images.

Shooting from Live View: Unnecessary. Frame and focus with it, then save battery, heat, and (with my DSLR at least) extra mirror flapping.

Mirror lockup: Really depends on your particular setup and the length of your exposures. If you've a solid mount and are doing minutes at a time, the excess vibrations from the mirror are going to have very little effect on end-game image quality. Wobbly tripod and 2-second exposures, not so much.

Just to confirm, when shooting from APT, I always close the flipping screen of the camera. Is this the correct way?

Sorry for using this thread.

You might want to leave the DSLR screen flipped out, that lets a bit more cooling air get to the back of the camera. 

Turn off the display of course, and watch out for it catching on things as you track and slew.

Another source of heat within a DSLR is the battery itself, this can be eliminated by using a battery grip or remote power with a dummy battery.
