Other readers, card adapters and undisclosed firmware behavior are outside this captured evidence. Use the original manual instead of trying a similar-looking slot. Independent content review remains pending.

Selected camera slot context

Canon / camera

Canon EOS R5 Mark II

Card 1 — CFexpress B

CFexpress Type B card interface

1 physical slot. S120

Card 2 — SD

Full-size SD card form

1 physical slot. S120

Model scope, caveats and source dates

Canon EOS R5 Mark II only. Do not substitute a similarly named reader, later revision or regional bundle.

  • Family support does not approve every capacity or recording mode. Check the current recording-media specification and firmware.
  • This profile is EOS R5 Mark II, not the original R5, R5 C or another Canon body.

No automatic USB handoff. Camera direct transfer, USB4 negotiation and alternate or captive upstream topology require a separate documented workflow.

  • Recording format, bitrate, card speed class, firmware and exact-card suitability remain separate checks.
  • Selecting Slot 1 does not reserve or configure it; the worksheet does not read or change the camera.

A practical learning path

Check the right question next.

Choose a card reader without guessing from its shapeTreat the card family, exact reader and upstream computer connection as separate checks.XQD and CFexpress: check the reader, not just the outlineSimilar physical forms do not establish shared reader support.Read a camera card-slot map correctlyA shared opening and two separate openings are different physical arrangements.The reader-to-computer USB checklistThe reader’s media slot is only one side of the connection.Recording support is not the same as offload supportA camera recording requirement and a reader transfer requirement answer different questions.A non-destructive card-offload planning checklistPrepare an evidence checklist without formatting, repairing or modifying the card.

Evidence beyond the card shape

Read the distinctions that matter.

Is CFexpress Type A or B the same as its generation?Separate the physical type, specification generation, protocol and exact equipment support.Does an XQD slot automatically support CFexpress Type B?Use an exact firmware example without extending it to every camera or reader.What do UDMA, UHS and USB mean on a multi-card reader?Keep each card slot’s interface separate from the computer connection.Do two supported card families mean two usable slots?Distinguish alternative cards, physical slots, insertion and simultaneous access.Is VPG the same as a card’s read speed or USB speed?Check sustained-write profile requirements separately from offload claims.
