The Linhof Technika IV is a German-made 4x5 large format folding field camera, introduced in the mid-1950s as part of Linhof's Master Technika lineage. It was positioned as a precision professional tool for studio, landscape and commercial photographers requiring movements in a portable metal-bodied platform.

At UK auction, hammer prices for the Technika IV today sit in a narrow £200–£210 band based on the limited recent saleroom record, with a median around £205. Values in the auction market are highly condition-sensitive: examples with a working rangefinder, matched cams, original lensboards and a clean bellows tend to sell for materially more than body-only lots, so a buyer asking what a Technika IV is worth should weigh completeness heavily.
