Adorama has the first bundle for the GFX100 with savings on the Mitakon Zhongyi Speedmaster 65mm f/1.4 and Mitakon Zhongyi Speedmaster 85mm f/1.2 for GF mount. These are manual lenses designed for full frame, but able to cover the GFX’s 44 x 33mm sensor so Mitakon put a GF mount on them. They should work quite well with IBIS on the GFX100.
