have you tried before using ISO1600,F2.8 indoor in a banquet?
can you give a rough idea how will the shutter speed like?
Assuming given mid range zoom of f2.8 aperture unless you are shooting 85mm f1.2 or 50mm f1.4 through out which is highly unlikely.
depending on the lighting really.
with spotlight (on stage, during march in), around 1/250 (can even be faster)
with very dim ambient light, 1/15?
anywayz, on the topic of shooting without flash, it's definitely possible, and i would say iso800 isn't enuff.. u need iso1600.
also, shooting at f1.4 even if you have the lens is not feasible. even at 2.8 you have to deal with a pretty shallow DOF. couple that with slow shutters at times (even if you are stable as a rock, pple do move) it's a very very difficult task.
do what most of us do. mount the flash, use it when you need to, don't die die also dun use flash, just to prove that it's possible.
the shots below are all "flashed" at a wedding banquet.... i think most of you might agree it doesn't look that "unnatural" does it?
