Work work. The H only takes leaf shutter lenses. I did successfully mount the FE 110 F/2 on my Contax 645 with great results.
I also have the 110 on my contax, but don't use it often except for those once in a blue moon, one eyeball in focus images.
We all love fast lenses, but rarely does everyone shoot wide open.
But why the 110 hasselblad makes a great 100mm H lens at f2.2 which I think is the Jewel of their lens line.
