The Rollei Mutar 0.6x is a wide-angle auxiliary lens attachment made by Rollei for use with twin-lens reflex cameras, fitting over the taking and viewing lenses to broaden the field of view. It is an accessory rather than a standalone camera, used by Rolleiflex TLR owners who needed wider coverage than the fixed lens permitted.

Sales data for the Mutar 0.6x is extremely thin: a single UK auction hammer result from January 2021 sold for £273, and there are no further records to establish a reliable median or range as of today. Because this is a wholesale saleroom price rather than a dealer asking price, retail value in 2026 is likely higher, but the limited history makes any precise figure on what one currently sells for speculative.
