{"overview":"The Dallmeyer 4 Inch f\/1.9 Super Six is a fast 4-inch (approximately 100mm) prime lens from the British maker J.H. Dallmeyer, dating to the mid-twentieth century. The Super Six series was developed as a high-speed optic for cine and professional photographic use, and at f\/1.9 it sat among the fastest lenses of its class in the British market.","market_narrative":"At UK auction in the saleroom, two recent hammer results frame the picture: £4,788 in July 2025 at Chiswick and £8,500 in May 2024 at Flints, giving a midpoint near £6,644 — these are wholesale-level results before commissions. The wide spread shows how strongly condition, completeness and mount configuration influence what a Dallmeyer Super Six is worth today in 2026, with clean, presentable examples sitting at the upper end of the range. Buyers should expect retail asking prices from specialist dealers to sit above these auction figures.","buying_guide":"Inspect the glass carefully for fungus, internal haze and cleaning marks, all of which are common in pre-war and post-war British optics of this age, and check for any signs of element separation or balsam degradation visible as edge discoloration. Examine the iris for oil on the aperture blades and confirm the focus helicoid turns smoothly without stiffness or grease migration. Mount type and the presence of original caps, flange or adapters materially affect what the lens sells for.","specs":"Listed specifications are limited to the 4-inch (≈100mm) focal length and an f\/1.9 maximum aperture under the Dallmeyer Super Six designation; mount, element count and coating details are not documented in the provided data.","faq":[{"q":"What is a Dallmeyer 4 Inch f\/1.9 Super Six worth at auction?","a":"Recent UK hammer prices range from £4,788 to £8,500, so the lens has a current value broadly between those figures depending on condition, mount and completeness."},{"q":"How much does a Dallmeyer Super Six 4 Inch f\/1.9 sell for in clean condition?","a":"A clean, presentable example with good glass sells for towards the upper end of the recorded range, with the May 2024 Flints result of £8,500 illustrating what a strong copy can achieve at saleroom level."},{"q":"Why is the price range for this lens so wide?","a":"Condition issues such as fungus, haze, oil on blades and separation, together with mount variant and originality of fittings, drive a wide spread between the lowest and highest auction results."},{"q":"Are the quoted prices retail or wholesale?","a":"All figures cited here are UK auction hammer results, which represent wholesale levels before buyer's and seller's commission rather than dealer retail asking prices."}],"confidence":40,"reasoning":"Only two sales records are available and SPECS\/variants\/facts are empty, so confidence is capped per rule 8 and limited to model name, focal length, aperture and the two hammer prices."}

{"overview":"The Dallmeyer 1 Inch f\/1.9 Super Six is a fast normal-to-short-focus lens from the British maker J.H. Dallmeyer, designed in the Super Six series that the firm produced for small-format cine and scientific use. With a 1-inch (approximately 25mm) focal length and an f\/1.9 maximum aperture, it was built for low-light work on 16mm cine cameras and similar compact formats from the mid-twentieth century.","market_narrative":"At UK auction the Super Six 1-inch f\/1.9 has a thin but consistent record: hammer prices in the saleroom range from £160 (November 2025) to £275 (August 2022), giving a midpoint of roughly £217. As of 2026 these wholesale hammer results suggest clean examples sell for the upper end of that band, while optically tired copies trade nearer the lower figure, and buyers should remember auction values exclude commission and sit below dealer retail.","buying_guide":"Inspect the front and rear groups under a torch for fungus, haze and cleaning marks, as uncoated or lightly coated pre-war glass of this vintage is prone to bloom and etching. Check the iris for oil on the blades and confirm the aperture ring clicks or sweeps smoothly, and rotate the focus helicoid through its full travel to detect dried grease, stiffness or play. Confirm the mount is intact and matches your intended camera, as Dallmeyer supplied the Super Six in several cine fittings.","specs":"Key specifications confirmed by the data: 1-inch (25mm) focal length, f\/1.9 maximum aperture, branded by J.H.

{"overview":"The Dallmeyer 1¼ Inch f\/1.9 Super Six is a high-speed cine lens with a 31.75mm focal length and an f\/1.9 maximum aperture, made by the London optical house J.H. Dallmeyer. It belongs to the classic Super Six line, designed for small-format motion picture cameras of the mid-twentieth century.","market_narrative":"UK auction evidence for this lens is thin: a single recorded hammer result from May 2025 at £562 (saleroom level, before commissions) gives the only firm price anchor for what a Dallmeyer 1¼ Inch f\/1.9 Super Six is worth in today's market. With just one data point, the median and range collapse to that same figure, so anyone asking how much one sells for in 2026 should treat £562 as indicative rather than definitive, and expect condition, mount and presentation to swing the actual value either way.","buying_guide":"Inspect the front and rear elements under a torch for fungus, haze and cleaning marks, as Super Six glass of this era is prone to internal bloom and coating wear. Check that the iris blades are clean and dry with no oil migration, that focus and aperture rings move smoothly without stiffness or grinding, and that there is no separation visible at the cemented element edges. Confirm the mount is intact and matches your intended camera, since cine lenses of this period appear in several fittings and adapter quality affects value.","specs":"Recorded specifications are limited to the headline figures: a 1¼ inch (approximately 31.75mm) focal length and an f\/1.9 maximum aperture, in the Dallmeyer Super Six series.","faq":[{"q":"What is a Dallmeyer 1¼ Inch f\/1.9 Super Six worth today?","a":"The only verified UK auction hammer price on record is £562 from May 2025, so that figure is the best current guide to value, subject to condition and mount."},{"q":"How much does a Dallmeyer Super Six 1¼ Inch f\/1.9 sell for at auction?","a":"One UK saleroom result is logged at £562 hammer; with a single data point the price range and median both sit at that level until further sales are recorded."},{"q":"Is the Dallmeyer Super Six a cine lens?","a":"Yes, the Super Six line was produced by J.H.

{"overview":"The Dallmeyer 1½ Inch f\/1.9 Super Six is a fast projection lens from the long-established London optical maker J.H. Dallmeyer. With a 1½-inch (approximately 38mm) focal length and an f\/1.9 maximum aperture, it was built for cine and slide projection rather than camera use, and is most often encountered today as a brass- or alloy-barrelled unit adapted by enthusiasts to mirrorless bodies for its rendering.","market_narrative":"At UK auction, hammer prices for the Super Six 1½ Inch f\/1.9 Projection lens have sat in a narrow band, with recorded results of £682 in November 2020 and £725 in August 2022 — a median around £703. As of today in 2026 these saleroom levels suggest a clean copy is worth roughly £680–£725 at wholesale, before buyer's premium, and dealer or adapted-for-mirrorless retail asking prices typically run higher than what the lens sells for under the hammer.","buying_guide":"Inspect the glass carefully for fungus, haze and cleaning marks, all of which are common on Dallmeyer projection optics of this age, and check that internal coatings (where present) are free of scratches or wipe damage. Because this is a projection lens there is no iris to gum up, but confirm the focus helicoid (or any added adapter helicoid) turns smoothly, look for signs of element separation at the cemented groups, and verify the barrel is complete and undamaged since missing retaining rings sharply reduce value.","specs":"Key documented specifications are limited to the maker (J.H.

As of 2026, that single data point suggests the lens sells for a low four-figure sum at saleroom level — a wholesale hammer result before buyer's and seller's commission — but with so few comparables, the true market worth and price spread for a clean, working copy could vary materially from this benchmark.","buying_guide":"Inspect the glass carefully for fungus, internal haze and coating scratches, all of which are common in older British optics and materially reduce value. Check the iris for oil on the aperture blades and confirm the diaphragm opens and closes smoothly, and verify the focus helicoid turns evenly without stiffness, dry grease or play. Also look closely at cemented groups for any signs of separation or balsam discolouration, and confirm the mount and engravings are original and undamaged.","specs":"Specifications recorded for this listing are limited to a 1½-inch (≈38mm) focal length and an f\/2 maximum aperture under Dallmeyer's Super Six branding; no further verified data is available in the supplied source material.","faq":[{"q":"What is a Dallmeyer 1½ Inch f\/2 Super Six worth today?","a":"Based on the single UK auction record we have, a Dallmeyer 1½ Inch f\/2 Super Six is worth around £1,364 at hammer, though with only one verified sale the realistic value range for any individual copy is uncertain."},{"q":"How much does a Dallmeyer Super Six 1½ Inch f\/2 sell for at auction?","a":"The one recorded UK auction sale fetched £1,364 hammer in December 2021; clean, fungus-free examples in original condition would be expected to achieve the strongest prices."},{"q":"Why does the price of this Dallmeyer lens vary so much?","a":"Condition is the dominant factor — fungus, haze, separation, oil on the blades and a stiff focus helicoid all sharply reduce value, while clean glass and smooth mechanics support the upper end of the market."},{"q":"Is the Dallmeyer Super Six a cine lens?","a":"The Super Six designation was used by J.H.
