Yes I did evidence photography & weddings and such, I own Cannon 1 DX ,5 D M III as well as a buttload of "L" glass , I also have a t3i that I use for dedicated non visible spectrum , the 5 D has also been modified removing the main sensor , replaced with an Astral photography sensor with out ant-aliasing feature, I shot alot of HDR and infared these days , ice and ice dunes are one of my most favorite things to shoot, and like you I hang on to my Nikon F3 HP titanium with bulk back from back in my film days , there was no better press cameras back then.
