Hey guys.

I have a Canon 550D with the twin lens kit but looking to get a better lens than the ones supplied.
Im looking for a lens that will be a better performer for basic untracked night shooting aswell as being able to be my day-to-day lens.

I originally thought the Canon 50mm f1.4 but the crop factor of 1.6 on this camera would mean its far from a wide angle that would be ideal

So, the below is what im thinking of:
-Canon 50mm f1.4
-Sigma 50mm f1.4
-Sigma 30mm f1.4
-Canon 28mm f1.8
-Sigma 24mm f1.8
-Sigma 20mm f1.8


I dont want to put all my money into it so im looking second hand around the $250-$300 mark.
What of the above would be a best lens to add into the 18-55, 55-200 cheapies that come with the 550D.
It would also be nice if it would fit full frame cameras if i was to upgrade in the future.

Thanks,
Luke
