The Rolleiflex SL 66 'Bundeswehr' is a medium-format single-lens reflex camera, a military-marked variant of Rollei's SL 66 system introduced in the late 1960s. The standard SL 66 was positioned as a professional 6x6 SLR competing with Hasselblad, and the Bundeswehr designation indicates examples supplied to the West German armed forces.

Auction data for this specific Bundeswehr variant is extremely thin: a single recorded UK auction hammer result from 2012 sits at £900, which is a wholesale saleroom level rather than a retail asking price. With only one data point on file, today's value is difficult to pin down, and what a 'Bundeswehr'-marked SL 66 sells for in the current market will depend heavily on completeness, condition, and buyer demand for military-issue Rollei medium format. Expect military-marked examples to command a premium over civilian SL 66 bodies when provenance is documented.
