Ihagee Exakta Diamant (prototype)
The Ihagee Exakta Diamant is a prototype camera from the German manufacturer Ihagee, the firm best known for the Exakta line of single-lens reflex cameras. As a prototype rather than a production model, it never reached series manufacture, which is the central factor shaping its value today.
With only a single documented UK auction hammer result on record — £5,500 in November 2011 — the Exakta Diamant prototype sits firmly in collector-grade territory rather than the user market. Because that figure is wholesale at saleroom level (excluding buyer's and seller's commission), what a Diamant is worth today in 2026 depends almost entirely on provenance, completeness and the bidder pool on the day; a comparable example could realistically sell for a broadly similar five-figure sum or move materially in either direction.
Sales History
Prices shown are realised prices — auction results and completed eBay sales, never asking prices. Most saleroom figures are hammer prices, before commission; some houses publish a premium-inclusive figure, and we do not adjust for condition. Dealer and retail asking prices are typically higher. How this figure is calculated.

Frequently asked questions
What is an Ihagee Exakta Diamant prototype worth?
The only recorded UK auction sale, in November 2011, achieved a hammer price of £5,500, which is the single reference point for what this prototype sells for.
How much does an Exakta Diamant prototype sell for at auction?
On the available evidence, the value sits in the multi-thousand-pound range, with one documented hammer result of £5,500; thin sales data means any individual price is highly provenance-dependent.
Why is the price reference for the Diamant so limited?
Because the Diamant was a prototype rather than a production Exakta, surviving examples almost never come to market, so there is no meaningful range — only isolated data points.
