A prototype Leica camera has sold for 2.16 million euro, setting a new world record for a camera.
It was one of just 25 models created in 1923 as a prototype for the groundbreaking Leica A - the first commercially successful compact camera to use 35mm film, the BBC reports.
Branded the "null-serie", or 0-Series, only 12 are known to have survived.
The camera was bought by an anonymous bidder at the Galerie Westlicht in Vienna, Austria.
The bidding on Saturday started at 300,000 euros, with an estimate of 600,000 euros.
But by the time the hammer fell, the bids had escalated to 1.8 million euros. The remainder of the sale price included taxes and fees.
The previous record was also held by a 0-Series Leica which fetched 1.32m euros. In 2007, that camera had been auctioned for just 336,000 euros.
Leica was founded in 1849, specialising in the development of lenses and microscopes.
