I took A7RII and 24-240 to weekly bridge game.
Where we play at the club is near large windows so there was quite a bit of light, but farther away from the windows is relatively dark so there is some nearly black shadow areas.
Camera was set for center weighted exposure. Av, F6.3 and ISO at 6400, 12800 and 25600.
F6.3 is wide open for this lens at the selected focal length.
EXIF is attached to the files if anyone wants to look.
6400 No Lightroom adjustments other than import with Camera Profile created with Adobe DNG Profile Editor.
I don't think I'm going to be too worried about ISO "grain" during receptions.
