i m using 18-55mm 3.5-5.6 kit lens and since i need to shoot in low light conditions (christmas is coming ), im thinking to get a 50mm f1.8G.

What i have in mind: bokeh of christmas tree lightings, candle lights, romantic dinner, night scenery, etc

Comments?

The 50mm is pretty inexpensive and you can't go wrong with that.

If you really look for the shallow depth of field and larger aperture(more light), go for it.
Just a warning though, lots and lots of bokeh =/= auto awesome pics that everyone loves.
