The Hasselblad 40mm f/4 CF Distagon is a wide-angle prime for the V-system bayonet, introduced in the 1980s as part of the CF generation that replaced the earlier chrome and black C-mount Distagons. It covers the 6x6 medium-format frame and was designed for architecture, interiors and landscape work where the widest available perspective on a 500-series body was required. The CF housing brought a redesigned barrel with the Prontor CF shutter, allowing use in both leaf-shutter and (with appropriate bodies) focal-plane modes.

At UK auction in recent years the 40mm CF Distagon has changed hands at hammer between £700 and £975, with most clean copies settling in the £840 to £900 band — a median around £859 across the sales recorded here. The most recent saleroom result, in April 2025, was £975, suggesting values for tidy examples remain firm into 2026 rather than drifting. Buyers should remember these are wholesale hammer figures from UK rooms; what a 40mm CF is worth at retail from a dealer typically sits well above what it sells for under the gavel.
