GH2 Fast, Affordable Prime with larger barrel for use with follow focus? 20-30mm?

[Silenkiller]

So, I've discovered my 20mm 1.7 pancake from panasonic is about two times two small to function with my follow focus rig - so I'm looking for something that does a similar job, but can be much larger so my gear system can wrap around it lol.

Any suggestions? I'd like to be fast 1.4-1.8 and also not more than 400 bucks if possible. I'm looking for a lens I can make my primary cinematography tool ;p

I've found the Panasonic Leica D Summilux Asph 25mm F1.4 but it is too expensive. Must be some cheaper alternatives.

Definitely take a look at the sigma 20mm 1.8, I got mine used the other week on eBay for just over 400. Check my sig for sample footage with the lens if you're interested.
