photography still on my mind

anybody out there shoot RAW+JPEG? roughly how big is the pair of files each exposure produces? one possibility for making the panasonic 45-175mm lens work with the e-m5 is always shooting that way, using JPEGs for my nearly all of normal workflow™, but then using the RAW files to work up those pictures from the 45-175mm that i want and would benefit from it.

i found a large collection of sample pictures taken with that lens on an oly body. unsurprisingly, pictures without abrupt transitions between saturated colors on opposite sides of the color wheel are less effected by CA than otherwise.
