<p>When browsing amazon for the CF adapter linked to earlier in the conversation, I noticed a related item which fits CF Type I slots!<br>
https://www.amazon.com/DIGIGEAR-SLIM-CF-Adapter-WiFi-SD/dp/B00XO2KSEO<br>
It has reviews saying that it'll fit Nikon D3s, Nikon D4, Nikon D4s, Nikon D700, Nikon D800, Canon 20D, Canon 300D (8GB limit), Canon 350D, Canon 40D, Canon 5D mark III, Canon 7D mark II.<br>
Caveats:<br>
- Need to remove CF adapter to get SD card out of camera.<br>
- EyeFi cards not working properly<br>
- 25 MB/s speed limit (one older review mentioned a 12 MB/s speed)<br>
- No spring (i.e. can't push in the SD to have it pop out)<br>
- Older reviews state it breaks after a couple of uses, this seems to have been fixed<br>
Still, if the alternative is to have to buy a stack of new cards for a new body when you still have SD cards to spare...</p>
