Mamiya 43mm f/4.5 · 7

{"overview":"The Mamiya 7 43mm f\/4.5 is an ultra-wide-angle lens for the Mamiya 7 and 7 II rangefinder medium format system, designated by the 'N' prefix convention used across this line. With a 6x7 image circle, it is one of the widest rangefinder lenses ever produced for roll film and was designed for landscape, architectural and interior work where an external viewfinder is used for framing. Its worth and value reflect both its specialist optical role and the limited production of the Mamiya 7 system overall.","market_narrative":"At recent UK auction, hammer prices for the 43mm f\/4.5 have ranged from £252 to £529, with a two-sale median of around £390 based on the limited data set. These are saleroom results — wholesale levels excluding commission — and as of 2026 the lens still sells for considerably less than retail dealer asking prices, though the small sample means any single result can skew the picture. Copies offered complete with the matching external viewfinder typically command a premium over lens-only listings.","buying_guide":"Inspect the front and rear elements for fungus, haze and cleaning marks, as the large front group is exposed and multicoated surfaces scratch easily. Check the leaf shutter fires cleanly at all speeds and that the aperture blades are dry and snappy with no oil migration, since the shutter is inside the lens rather than the body. Confirm focus is smooth without stiffness, look for any signs of element separation at the cemented groups, and verify the dedicated external viewfinder is present and undamaged, as a missing finder significantly reduces usability and resale value.","specs":"Ultra-wide prime for the Mamiya 7 rangefinder mount, focal length 43mm at a maximum aperture of f\/4.5, covering the 6x7 format.","faq":[{"q":"What is a Mamiya 7 43mm f\/4.5 worth at UK auction?","a":"Recent UK auction hammer prices have fallen between £252 and £529, so a typical saleroom value currently sits in the middle of that range depending on condition and whether the external viewfinder is included."},{"q":"How much does a Mamiya 7 43mm f\/4.5 sell for compared to other Mamiya 7 lenses?","a":"As the widest lens in the range it tends to hold its price well, and recent results up to £529 suggest it sells for more than the more common standard-length N-series optics when complete."},{"q":"Does the price include the external viewfinder?","a":"Not always — the viewfinder is a separate accessory, and the recorded auction prices do not specify inclusion, so buyers should confirm before bidding as a missing finder materially affects value."}],"confidence":45,"reasoning":"Only two sales records are provided and no SPECS or variant facts, so market figures are directional and technical detail is limited to widely-known system categorisation."}
