Pros: Its probably a very good card

Cons: Will not work with a D300. D300 takes 32GB max.

Overall Review: Sigh! I was waiting for this card and ended up with a "Card Full" error on an empty card. Browsed the web for similar experiences and found out that the D300 will take cards to a maximum size of 32GB. Hoping that a future Nikon firmware update might take care of this problem, but it seems unlikely. Seems that Nikon did make the firmware upgrade for the D300s.
