I'll take a crack on this one.
My main camera is still a digital Pentax camera. Pentax K-7 usually with DA*55 F1.4.
I have now include a Pentax 645 and Bronica ETRS (both with 75mm F2.8 lenses).
In essence I have 2 film main cameras and the digital is a main, but also a backup.
I'm using Kodak Portra 400, Ilford Delta 400 and Ilford Delta 3200. Love the colors!
