I use a 54 LV too. Much improved in the shadows over the eMotion 22, though I still work at 50ASA.
My workflow is: BRUM > DNG > ACR
I like to get into the Adobe universe as quick as possible and I'm looking forward to the firmware upgrade that gets the back outputting DNGs. Nice!
I'm not too smitten with Captureshop and prefer Mister Brumbaer's elegant substitute. It's just simpler, that's all.
