Summary: If you are going full frame and don't want to spend for a brand new camera, then the D700 is a great choice. Low light and sharp photo's are first rate, however, you do need good glass to accomplish this. The camera alone will not make great photo's. This is not your light weight camera. If you are looking for that, then this is not the one for you.
Summary: I am a pro photographer - This camera is simply the best full frame. The file sizes are manageable, and I can still print 6 foot by 4 foot images should I choose (Don't believe the megapixel hype). I've owned this camera for a few years now and it's yet to disappoint. Couple it with a 24-70 F2.8 or 50mm F1.4 and it's magic.
Excerpt: I bought my D700 back in December of 2010. I used it for 2 full years and I just checked the shutter count and it has taken 150,150 shots! So yes, I've used it heavily, mostly model shoots --some studio and some on location. This camera became a part of me and it was very hard to switch to anything else.
Summary: Nikon's original 12.1-megapixel FX-format (23.9 x 36mm) CMOS sensor: Teamed with Nikon's exclusive EXPEED digital image processing, the D700 delivers breathtakingly rich image quality. Continuous shooting up to 5 frames per second: Shoot at up to 8 frames per second with the optional MB-D10 Multi-power Battery Pack. Two Live View shooting modes: Choose from hand-held or tripod modes to suit shooting requirements.
Summary: This is probably the most reliable full frame digital camera Nikon has produced to date. No flaky left side AF problems like the D800 and no oil/dirt on the sensor problems like the D600. It doesn't do video like either of those cameras, only has 12 megapixels, and doesn't have as much dynamic range, but apparently remains the camera of choice for many stills-only dedicated pros who don't want any issues and just want to shoot away.
Excerpt: Great deal on this hard to find camera. Thought about buying a used one, but you never know what it's been through. Nikon's refurbished products look and feel like new and have a 90 day guarantee. Have been using a Nikon D300 with 24mm, 50mm and 80-200mm. Now with the FX sensor, it's like a have another set of lenses. I really like the 24mm on the D700 for landscape.
Under the circumstances, D700 is the best camera for my top AIS lenses.

Summary: There are two reasons I bought the Nikon D700 in February 2013 -- after it was discontinued. 1. I have had the Nikon D300 for years, but wanted a full frame camera to take full advantage of my top quality manual lenses. I like the slow pace of manual photography. 2. My son had outgrown his D70s and he likes manual photography too. I considered the D600, but missed the AF-ON button and the direction pad center button zoom.
