Power Down for lens changes?

[Jarek Zabczynski]

Do you guys power down for lens changes?

I use to at first but then started not due to time constraints. Any issue with me doing so?

I never powerdown for lens change. No issue for me.

There is no need to power down.

Only time i do is if in an dusty environment to minimise dust been sucked in by the fan but otherwise never.

I only do this when it's time to change the battery soon (to do it in "one step" - as for dust & co; as a DIT/camera assistant I always carry a mount-cap with me to avoid this)... but usually; no time for a power-down between shorter takes - especially in run & gun or live/docu situations... If there appears to be any problems or glitches after a lens-change (you usually should see it on the monitoring-path, so always keep an eye on your monitoring) you'll still have the time for a reboot...

I was looking at it from the perspective of flooding the sensor with so much light.

No problem with doing that.

as long as you don't point directly towards piercing sun or other very very bright or dangerous light sources (e.g. Laser or an open fire/glow-source or focussed/burn-pinted spots or curved mirrors) I don't see any problem… For changing the lens you can always use the "cover-mount with-flat-hand" method or if it takes you longer you can mount a mount cap (the plastic ones should do it) in the meantime…
