Sony Nex-5 Kit 16mm Or a cheap alternative?

[Sandtrap101]

Hey, Im new to photography and don't actually have a decent camera yet :/ I'm looking at the Sony Nex-5 for shooting video with a lot of movement. I was thinking of getting the 16mm kit lens because its quite wide angle the capture my subjects from close up. BUT i'm not sure wether it would be a good lens or not and was wondering should I get the whole thing for around £300 or go with a body for around £140 and look for a lens for about £200 or is that too cheap for a good lens .
Thanks.
