Sigma 17-70mm f/2.8-4 DC Macro HSM

No sale of this model has been watched yet.

The estimate blends recent sales with the median asking price. Each sale counts less the older it is, and the more recent sales there are, the more they carry: with none it is the asking price, with 5 recent ones half and half. So it moves gradually, never in a jump. Figures resting on fewer than that are marked low confidence. In an asking median no shop counts for more than a third (or an equal share, with fewer shops), so one shop’s price list does not decide it. Parts-only and brand-new units are left out. (1 here)

Kamerastore Certified is Kamerastore’s own published average for units it grades Certified (tested and working), read 2026-10-10. It is their figure, not Kamarvo’s, and is not part of the estimate.

Prices quoted in EUR, USD are converted to EUR before the median.
