Hasselblad 500ELX and Flexbody with 40, 50, 80, 120, 180, 250SA, 500APO.
My 1DsII sidelined my MF system big time but I have still found some use in BW work. I do not like a number of conversions from digital to monochrome if any extensive use of channel mixer is applied as the noise gets really bad. I do not know how anyone accepts those results. So if I want the effect of a red filter etc I much prefer monochrome film.
I am also experimenting with MF infrared, (Rollei)
