Budget glass options for BMPCC

So I'm planning to pre-order the BlackMagic Pocket Cinema Camera, I also have a pretty tight camera budget. As such a collection of $600+ lenses is way above my wallet's limit.
I figured I'd post here for ideas on what to get on a budget (which can obviously help others in a similar situation). Searching eBay, Amazon etc isn't too helpful as there are piles of generic glass which I can only imagine is hideous.
Me personally, I like wide lenses or a versatile zoom lens. However I was thinking that it might be handy for others if people just suggested quality <$500 glass for the BMPCC, not just MFT but any adaptable mount that will work well with BMPCC.
So people for under $500 what lenses are worth looking at?
