Hasselblad's fast databus portrait tele — the Zeiss Planar FE 110mm f/2 for electronic focal-plane V bodies.
The Carl Zeiss Planar FE 110mm f/2 is the databus version of the fast short telephoto for the focal-plane-shutter Hasselblad V bodies, adding electronic contacts to the F design so it can communicate with the metering 200-series cameras such as the 203 and 205. It shares the f/2 aperture that makes the 110mm the fastest lens in the V-system line.
This is a manual-focus Hasselblad V lens without a leaf shutter, the FE form keeping the shutterless F design and adding the electronic databus contacts for the later 200-series bodies. Its maximum aperture is f/2 and it covers the 6x6 frame as a Planar. It depends on the body's focal-plane shutter to fire, and the databus contacts allow the aperture-priority and metering features of the electronic V cameras to work with it.
The bright f/2 aperture delivers a luminous finder, strong low-light performance and shallow depth of field on 6x6, making the FE 110mm a favoured portrait lens on the electronic bodies. Wide open it separates a subject from a soft background with the medium-format rendering photographers prize, and the databus support adds accurate metering, so it pairs especially well with the 203FE and 205 cameras that can read it fully.
FE-series lenses are less common than CF glass and the 110mm is particularly sought after, so prices are high. Confirm it is the FE type for your 200-series body and that the databus contacts are clean and intact. Check the glass for haze, fungus and separation, inspect the large front element, verify the blades are dry and focus smooth, and test on a working electronic body since it has no leaf shutter of its own.
