Dallmeyer (J.H.) Brass Lantern Projection Lens
The J.H. Dallmeyer Brass Lantern Projection Lens is an early projection optic housed in a brass barrel, made by the long-established London optical firm founded in the Victorian era. Designed for use with magic lanterns, it was intended to project glass slides rather than to capture images, and it sits in the antique-projection category rather than alongside Dallmeyer's better-known photographic lenses.
Sales evidence is thin: the only recorded UK auction hammer result is £160 in June 2022, which sets both the known high and low and gives a single-point median of £160 at saleroom level. Because that figure is a wholesale auction result rather than a retail asking price, dealer-listed examples in 2026 are likely to sell for more, and condition of the brasswork and glass remains the main driver of what any individual example is worth today.

Frequently asked questions
What is a Dallmeyer Brass Lantern Projection Lens worth at UK auction?
On the single recorded UK auction sale, one example sold for a hammer price of £160 in 2022, so that figure is the only firm guide to current value.
How much does a Dallmeyer Brass Lantern Projection Lens sell for today?
With only one tracked saleroom result at £160, today's price for a comparable lens is best anchored to that hammer level, with clean brass and clear glass typically commanding the upper end and project-grade examples less.
Is this lens usable on a modern camera?
It was made as a magic-lantern projection lens rather than a photographic taking lens, so its value is driven by collectors of antique projection equipment rather than by users seeking a lens for a modern body.
What should I check before buying one?
Look closely for fungus, haze, separation and cleaning marks in the glass, and check the brass barrel and focusing mechanism for damage, stiffness or missing parts.
