SD to CF Type I Card Adapter

This internal power cable converts a CompactFlash Type I slot into an SD card reader supporting SD, SDHC, SDXC, and MMC formats. It is designed for photographers and technicians who need to use modern SD media in legacy CF-only devices such as older Canon and Sony cameras. The adapter enables memory mode and I/O mode operation for compatible hardware.

Up to 512 GB capacity support

The single specification that determines compatibility is the maximum supported capacity of 512 GB. Cards larger than this limit will not function, so buyers needing terabyte-scale storage must choose a different solution. The adapter also implements the SD 3.0 interface for faster transmission and stability within that capacity ceiling.

Sustained operation with FCC, UL, KC certification

Under continuous load the adapter maintains stable data transfer thanks to certified electrical compliance and robust contact design. It handles extended read and write sessions without the signal degradation common in uncertified converters. The package includes the adapter only, ready for internal installation in compatible slots.

Questions about this item

What does the 512GB capacity mean when I put this adapter in my camera?

The adapter accepts SD, SDHC and SDXC cards up to 512GB, so you can use a single high-capacity card instead of multiple smaller ones.

How does the CompactFlash Type I interface limit transfer speed in practice?

The CF Type I slot runs at the speed of the inserted SD card; the adapter itself adds no extra bottleneck beyond the card's own rating.

Will this adapter fit inside my Canon 5D Mark III battery compartment?

The adapter is a standard CompactFlash Type I form factor, so it slides into any CF Type I slot — including the one on the 5D Mark III — without modification.
