I owned a1000F many decades ago, which was introduced to replace the unreliable 1600F, although it was almost equally unreliable. Shutter and winding mechanisms are quirky and delicate. The 1600F deserves a place in a collector’s case because of the superior ergonomics and design concepts of the early Hasselblad cameras. After mine died I used Rollei TLR until arrival of 2000FCM, on which I could still use my Leitz, Zeiss, Kilfitt, and Nikon lenses with adapters. Now awaiting death of 2000FCM, but have successor, a 500CM with Hassy lenses. The success of Hasselblad is due to the way it sits in the hand. Nothing else comes close in MF SLR.
I would not buy a 1600F or 1000F as a user, only as a collectible. The Soviet cameras are 1000F clones. I would save my pennies for a Hasselblad C or after. I bought mine from KEH for a very fair price.
