Context

This model updates the previous EOS-1D series with a new imaging sensor, now offering 10.1 megapixels. It was positioned as a flagship professional DSLR at its launch, targeting sports and action photographers needing speed and durability.

Market

As of recent listings, used units are available for around $104. By 2013, used copies were already selling for less than a quarter of the original price, indicating a steep depreciation curve typical of high-end DSLRs superseded by newer models.
