Between my Hasselblads (500C, and 500EL/M), and my Rolleiflex Automat X, my other cameras see a lot less use than they used to...
Where I used to take my Nikon F3 or F4 out on the street, I now bring the Hasselblad, both day and night. For days when I feel like being a bit quieter, or just having a camera on my shoulder while being out and about in the event of something interesting happening, rather than actively out as a photographer, the Rollei is by my side.
Even my Pentax 6x7 feels a bit lonely these days, but that's mainly because I don't like using it in the cold, it's too bulky to handle comfortably with cold hands.
