Actually, I wanted to do the old EOS 300D only fit for SD cards. This works great. Moreover, I can now also access via iPhone to my pictures in the camera, because the adapter supplied my Transcend 16GB WiFi SD card easily power and communication (ASIN: B00A659IJI).
Note: The slot for the SD card is a "push-click", ie the card must lock when inserting and be pressed to take in order to disengage again. If they hinenschiebt simply, it is not working.
