The Leicaflex SL2 50 Jahre is a 35mm SLR produced by Leitz to mark the firm's 50th anniversary. It is a commemorative variant of the Leicaflex SL2, sold in limited numbers and aimed at collectors rather than working photographers.

Auction data for this anniversary variant is extremely thin: the only verified UK saleroom hammer result on file is £460 from 2005, which sets a historical reference point rather than a current market price. Because hammer prices are wholesale levels excluding commission, today a clean, complete example would typically be worth more than that figure, but a precise present-day value cannot be quoted from a single sale. Condition, completeness of the original presentation packaging, and matching documentation drive what this camera sells for far more than the underlying SL2 mechanics.
