The estimated value presented above is an average of 15 transactions recorded over the past years. This should be taken as guidance only, as the value of a specific camera can be over or under the figure suggested here and further depends on how eager the seller and buyer are.
Leitz / Leica note: over 800 Leica variants are listed here, and recorded sales keep pouring in. It is impractical to record all sales, so I no longer update these models. I would assume Leica buyers would know what they are looking for and could independently assess its value.
