Yea, the bokeh and sharpness.

Not really, 50mm f1.8 at f1.8 is very teh soft, hence you have to step down a lot to get sharper image where else if you get 50mm f1.4 you don't need to step down a lot and your image won't go too dark. Certain primes are even better that it's sharp at wide open, and that helps a heap cause you don't need to step down a lot to get sharp images.
oh say so la. i thought you referring to both at widest aperture.

pumping ISO when using flash coz he wanna absorb more ambient light....

Yes,
neo_lam got the point. Firing flash thinking that it'll help to compensate your ISO is wrong thing. You'll end up with PnS-like shots where you have the subject brightly lit surrounded by dark background. ISO helps to preserve the ambient lighting.

yes, going by what you guys posted - it's fine but for the ambient lights it could be done via aperture / shutter speed without having to pump the ISO.
cos i look at his pics, the ambient isn't all too dark and neither are they distant lights. he doesn't look like firing direct enough to create dark background either.
that's why i asking him - not you guys.
