It all depends on what kind of shots you wanna get.
If you're talking about lens which can give you a handholdable speed, then the 50mmf1.8 is a good choice.
If you are talking about long exposures, then a zoom might do better.
hmmm.. i now headache cause dun 1 2 spend so much on lens hehe mi poor boi mr Jedi (which jedi r u ? hehe) hmmm mi thinking of getting a holdable lens to walk around orchard at night and take picz, so a 50mm wif f/1.8 is gd right ? this lens can also take scenery right ?
I dun think you want to take soft pictures of the night scenery at f1.8
Most users normally take pics of night scenes at apertures of about f8 or smaller to have a longer DOF. And in that situation, you'd need longer shutter speeds too. So a tripod is often used.
As for night street shooting of certain objects or ppl, then you may wanna consider the 50mm f1.8, but note that the DOF is very think at f1.8... also on a DSLR, it's abt 75mm perspective, not very useful for scenery...
