When I was on my Nikon African Safari in Sabi Sabi South Africa, not only did Nikon loan me some nice long glass, but they also supplied me with some Lexar 1000x CF cards for my Nikon D4. To say that these cards performed well is an understatement. When I got home I checked the price of the cards and of course I had slight sticker shock. However, these cards are now on sale with some deep discounts here.
