I have a Cooke 100mm Deep Field Panchro adapted to a Hasselblad F mount, so I own a 2000FCM just to be able to use it. Now with mirrorless I might sell the Hasselblad but on 6x6 it’s more useful as a standard lens.
I also own a Cooke PS945 a portrait lens for 4x5. Is a 229mm f4.5 lens in a Copal shutter. While it’s “useful” image circle only covers 4x5 it will fill a 5x7 frame at infinity but with the outer edges undefined instead of a hard fall off to black. I don't know how else to explain it. I keep a 5x7 camera to use this lens because it’s effectively a normal focal length at this format and I shoot it at f4.5 yielding effects not unlike a Leica Noctilux wide open.
