While the flagship Nikon D3 may be out of reach for some, the same FX-line power is now available at a more accessible price point in the Nikon D700 digital SLR.  The D700 shares the same 12.1 MP CMOS sensor with the D3, the active in-camera image editing system and many other features of the flagship model.  Some of the pro features are limited, like the ability to shoot 5 full-res jpegs per second as opposed to 10 on the D3.  But for those that don’t have $5k laying around for a D3, you can find this D700 for a whole lot less…

Its time to ditch your compact digital and think about an upgrade. When it comes to digital photography, most photographers will tell you there’s nothing better than a Nikon. And for Nikon, there’s nothing better than the Nikon D300 Digital SLR. SLRs take a little skill than your point-and-shoot compact. They have a wide array of controls, interchangeable lenses, expanded mount modularity and plenty of other pro features.  The Nikon D300, Nikon’s flagship, offers 12.3 megapixels, a 3 inch LCD display and the standard connectivity you’d expect from a high end digital camera.  Keep in mind that the megapixel number is not a yardstick of quality, as the grade of components, lenses and pre-storage processing have the greatest impact on image quality.  With that, you’ll find the D300 as the ultimate upgrade into a pro digital camera.
