My partner and I have had this conversation before...
If I was FORCED (on threat of a painful death there and then, in the kitchen and most likely with a blunt carving knife), I put put my back to the walll and probably opt for my two Rolleiflex Ts. As most here will know, these shoot 120 roll film. One has a 16 exposure kit. I also have a circa 1949 Rolleikin 35mm film back in almost pristine condition which fits the T models, so I could also shoot the so-called "miniature" films, the disadvantage with this kit being that the Rollei Tessar is then a short telephoto lens. Lousy for landscapes, but ideal for lovely close-ups of flowers or my ever ongoing series of home portraits of our house cats.
I also have the entire set of filters for B&W and color and the three close-up lenses for the Rollei Ts, as well as a full small carton of other accessories.
I would then sell every other camera kit I have at home, hopefully for a nice profit, and spend the dosh on myself and my partner when we fly to North America (US and Canada) in September, for what will sadly but surely be my last visit to my home towns in this lifetime. Of course I will be taking the Rolleis.
All this would simplify my photography to no end, as long as 120 roll film continues to be manufactured. It would also ensure that I would never again have to participate in a thread like this one.
