You carry and shoot with too many pieces of equipment for me. It seems very complicated and confusing to me but it seems to work for you. When I shoot MF film, I take along my Minolta IIIa that allows incidence and reflected measurements. It also measures flash for portraits. I've tried using a digital camera for the meter. It works but just complicates the process and only allows reflectance readings. Also, the MF system is too heavy as it is and carrying and using another camera for readings is too much.
