... Does the Mark IV not recognize/utilize the UDMA7 technology?
I can't answer the specific question, but I can say this: my 1DIV manual says it recognizes "UDMA-compatible" recording media, while my 1DX manual says it recognizes "UDMA mode 7-compatible" recording media. To me, this implies that the 1DIV doesn't use the full capability of UDMA-7 cards.
OTOH, the UDMA-7 cards may still download faster, depending on the card reader and port that you use.
