When I bought 1000F there was no alternative Hasselblad. Except for Ektar that came with camera I used a Kilfit lens which was later used on Leica after demise of my 1000F. Then much later bought Rollei 2.8F for MF. However, Hasselblad handled well and when 2000FCM came out I bought it because I could use many Leica and Kilfitt lenses already owned. At the time already having lenses made camera somewhat more affordable.
Sirius, as told to me, the early Hassy 1600 and 1000 shutter mechanisms were designed by a Swedish watchmaker and not by someone experienced in shutter design, which must be more robust...not to mention the need to follow a precise procedure for advancing film on 1000 and not mess up shutter (I did this twice and promptly got rid of camera). Perhaps someone on APUG can confirm or disprove this bit of hearsay about watchmaker designing shutter.
From my memorable experiences with 1000F more than a half century ago, perhaps in a museum of mechanical failures but not a shelf queen. Maybe a shelf lacky.
