{"overview":"The Leitz 15mm f\/3.5 Super-Elmar-R is an ultra-wide-angle prime designed for the Leica R bayonet mount, fitting the company's Reflex SLR bodies such as the R3 through R9. With its 15mm focal length and f\/3.5 maximum aperture, it was built to deliver an extreme angle of view for architectural, landscape and interior work on full-frame 35mm SLRs.","market_narrative":"UK saleroom data is thin for this lens, but a clean example fetched £1,750 at hammer in November 2022, which is the only verified auction result on file and stands as both the high and the median price in our records. As of today in 2026, that figure reflects what the 15mm f\/3.5 Super-Elmar-R sells for at wholesale auction level rather than dealer retail, where asking prices for fully serviced copies typically run higher. With only a single data point, the broader value range should be treated as indicative — condition, completeness of caps and hood, and optical cleanliness move the price materially.","buying_guide":"Inspect the front and rear elements carefully under a torch for fungus, haze and cleaning marks, since the large curved front group on ultra-wides is exposed and expensive to repolish. Check that the aperture blades are dry and snappy with no oil migration, that focus is smooth from infinity to close range without grit or stiffness, and that there is no edge separation or coating damage on the internal groups. Confirm the R-mount cam is intact and undamaged, and that the lens is the version you expect, as R-mount Leitz optics were updated through 1-cam, 2-cam, 3-cam and ROM iterations that affect compatibility with different R bodies.","specs":"Key specifications confirmed from the data: 15mm focal length, f\/3.5 maximum aperture, Leica R bayonet mount, prime ultra-wide-angle design from Leitz.","faq":[{"q":"What is a Leitz 15mm f\/3.5 Super-Elmar-R worth at UK auction?","a":"Based on our records, one verified UK hammer sale reached £1,750 in late 2022, so that figure is the best available reference for what the lens is worth at saleroom level today."},{"q":"How much does a 15mm f\/3.5 Super-Elmar-R sell for compared with retail?","a":"The £1,750 hammer price is a wholesale auction result excluding commission, so dealer retail asking prices for fully checked and guaranteed copies typically sit above this level."},{"q":"Will the 15mm Super-Elmar-R fit a Leica M camera?","a":"No — the -R suffix denotes the Leica R SLR bayonet, which is physically incompatible with M-mount rangefinder bodies; it is intended for R3 through R9 Reflex cameras."},{"q":"What should I check before paying a strong price for one?","a":"Prioritise glass condition (fungus, haze, coating scratches), dry aperture blades, smooth focus, and the cam\/ROM configuration matching your R body, as these factors drive the final value."}],"confidence":35,"reasoning":"Only one verified sales record and no SPECS or variant data were supplied, so confidence is capped well below 50 per rule 8."}
