If you are Nikon D700 owner - BUY THIS APP! – D700 DSLR Review

The Min-U Guide is a complete reference manual for your Nikon D700 in your pocket. No paper books to wrinkle up or get torn. Best of all, as the firmware in the camera is updated, Ken can issue updates to keep you current. Worth every penny!
