  • Supports micro-SD, micro-SDHC and micro-SDXC cards up to 512 GB capacity

Dual Micro-SD to CF Type I adapter

This adapter lets you use two micro-SD, micro-SDHC or micro-SDXC cards in a single CompactFlash Type I slot. It is aimed at photographers and technicians who need to keep legacy CF cameras or industrial equipment running with modern micro-SD media.

512 GB maximum capacity per card

Each slot accepts cards up to 512 GB, giving ample headroom for high-resolution stills or extended video clips. Speed and reliable operation depend entirely on the inserted micro-SD card; slower or incompatible cards may not function at all.

CompactFlash Type I 3.3 V interface

The adapter fits the standard CF Type I form factor and operates at 3.3 V. It supports UDMA transfer modes, but actual throughput is limited by the micro-SD card's own rating and the host device's CF controller.

Questions about this item

Will the 3.3V adapter work with my older Canon EOS 20D that uses a CF Type I slot?

The adapter fits CF Type I slots and runs at 3.3V, matching the electrical spec of the EOS 20D and other listed Canon bodies.

How can I verify the adapter is functioning correctly once installed in my camera?

Insert a microSDXC card up to 512GB, format it in-camera, then shoot a burst of images and confirm they playback without errors.

Does the package include a microSD card or only the 4.3 × 3.65 cm adapter itself?

The box contains one adapter card only; any microSD, microSDHC or microSDXC card must be purchased separately.
