Shooting side-by side, same subject and same exact 85mm lens@ f/1.8 using AE:
My Sony A1 chooses 1/90 sec / f/1.8 / ISO 800
My R5II chooses 1/125 sec / f/1.8 / ISO 2000
I want to get the Canon to choose lower ISOs, as it should here.
I noticed the same thing happening with a different R5II body about six months ago, shooting night scenes where the Canon would always unnecessarily fast shutter speed and choose ISO thousands higher than the Sony.
I know about changing the Minimum Shutter Speed Auto setting to a slower setting, but that just ends up with a too slow shutter, resulting in blur.
(just put that Shutter Speed Auto setting down to minus one, and now I'm getting 1/50 of a second with an 85mm lens. Obviously too slow.)
Any thoughts?
