Map Camera, the Tokyo retailer whose published used-body sales data functions as one of the few granular secondary-market records available outside manufacturer figures, consistently lists discontinued DSLRs near the top of its monthly volume rankings. Canon EOS 5D-series bodies, Nikon D750s, Nikon D5600s — cameras whose production lines closed years ago — turn over in numbers that current mirrorless inventory cannot match at equivalent price points. The pattern holds month after month.
The straightforward explanation is inventory depth. A camera discontinued in, say, 2020 has had four years to accumulate in the used channel from upgraders, estates, and photographers trading toward mirrorless. But volume alone does not explain ranking position: a used body has to sell, not merely exist. These DSLRs are moving. That means buyers are choosing them.

CIPA's interchangeable-lens camera shipment data supplies the structural context. The interchangeable-lens market peaked at roughly 12 million units shipped in 2012 and had contracted to somewhere below six million by the early 2020s. The overwhelming majority of units shipped between 2008 and 2018 — the decade when DSLRs made up the large majority of ILC volume — were mirror-based. That cohort of cameras did not disappear when Canon and Nikon ended DSLR development; it dispersed into the used market, where it is now the product.
What Map Camera's rankings proxy, therefore, is installed base. Every used Canon Rebel or Nikon D-series body that changes hands is a data point confirming that a substantial population of photographers still shoots with a mirror, still buys glass for those mounts, and — critically — is not converting at the rate the mirrorless pivot assumed. The Wikipedia summary of the DSLR market documents this long tail: DSLR production ran at industrial scale for more than a decade, and secondary markets absorb that output slowly.

For Ricoh, whose K-mount line remains the only current DSLR development program from a Japanese manufacturer, this picture is something other than bad news. The K-3 Mark III entered a market where the mirror-camera installed base is genuinely large, even if shrinking. Used-body rankings will not show up in CIPA's shipment tables, but they describe a constituency that still exists and still spends money on optics, accessories, and occasionally a new body.
The bodies nobody makes any more are also, demonstrably, the ones people are still buying.
