Quick help with Maya please!

[aphex]

Hey guys, I got to hand in some 3D work done in Maya in a few hours but I got a bit of a problem...I'm a total Maya noob but I've done my models etc and added DoF but when I render at production quality using Mental Ray the DoF blurs look really grainy. Is there a setting to make it smooth? Thanks!

Never used Maya myself, you might get better help on the cgtalk forums
they have a Maya section.
