I have an LX5 anything bigger would get in the way at work, I also have an S95 but it got damaged and I prefer the LX5 anyway.
Stills lens can be great but they can be a real pain to pull focus with so not so good for traditional moviemaking with actors that move around.
Lens I normally work with are Zeiss Master/Ultra Primes. Cooke S4/S5, Optimo zoom, Hawk anamorphic, Panavision anamorphic. The new Leica primes are interesting.
