So, where does the Nikon D3 differ from the D700? Well, for starters, it has that built-in battery pack that gives it a faster shooting speed, and a distinctive professional appearance. Continuous shooting is up to a speedy 9 frames per second for up to 130 JPEGs or 17 RAW files. The viewfinder covers a 100% view, (up from 95% on the D700), and the shutter is rated to last 300,000 cycles instead of the 150,000 on the D700. It has an extra memory card slot, and is about 350 grams heavier. The D3 is a classic model that will live long in the minds of pro photographers, however, it was released in November 2007, and will shortly be discontinued by Nikon, primarily because of the updated features on the later D3x and D3s models.
