If I shoot at 50mm, will the 50mm f1.8 stepped down to f4 have advantage over my 17-70 f2.8 @ 50mm f4. Will the depth of field be the same and will it have advantage in low light situtation?

At 50mm, and F4, on the same camera, both lenses will give you the the same depth of field, as well as low light performance. No low-light advantage whatsoever.

Heard of manual focus during night shots?
digitalpimp said:Not the focusing but the speed of the people walking I had problems with. I wanted faster shutter speeds to freeze motion. Heard of it?

Then increase the iso then pp lo.

Wow...
wise words indeed...

rhino123 said:Just a tot, bro... if you step up your ISO to around ISO3200 or more, maybe f2.8 will cut it. As for the amount of noise in the pic, we can always use pp to cut away the chroma noise...
Just a tot. However if people are walking very fast or your speed cannot reach fast enough, then very difficult to freeze motion.
