What's a good BMPCC run&gun lens for under $200? Cage?

So, for controlled shoots I shoot with a Sigma 18-35mm F1.8 with the BMPCC speedbooster but I need a more compact lens for fooling around, hiking with friends, more run and gun type stuff. So far I have been eyeing the Panasonic 14-45mm 3.5-5.6 lens as it has O.I.S. But if there are any other lenses worth looking at for under $200, let me know.

Any good cage recommendations? I've been eyeing the Viewfactor Contineo cage as it is only $100, does anyone know if this is a good cage?

As to the cage, I recommend the Contineo (don't forget the wooden grip The quality is incredible and - in my opinion - it is simply the coolest and most aesthetic cage for tme BMPCC.
