In addition, you can specify a fixed, minimum shutter speed value to ensure sharp pictures - this is generally most useful when you need a high shutter speed to freeze motion.
Nikon D800

Otherwise the Nikon D800 is a highly dependable and capable camera that offers a versatile and improved auto focus system, an enhanced viewfinder with 100% frame coverage and a very good movie mode.

ISO 6400 is where noise becomes more noticeable, although yet again it’s perfectly possible to make good images at this setting – especially if you are shooting in Raw and processing out the noise yourself.
Nikon D800

For example, in our shots taken a gym that was dimly lit by sodium lamps, chroma noise is clearly visible from around ISO 2500 when the images are viewed at 100% on the computer screen.

And it handles bright, saturated reds, pinks and purples very well, without blowing out any detail.

The Nikon D800 lets you dial in shutter speeds of up to 30 seconds and has a Bulb mode as well for exposure times of practically any length, which is very good news if you are seriously interested in night photography. Well duh, all the DSLRs do this. Don't make it look like the Canon 5d mark iii doesn't. The continuous shooting rate is also faster, 5 fps rather than 4 fps. This makes it look like the Nikon shoots faster than the Canon. Wrong again. The 5D iii has faster continuous shooting. Read the link below for really interesting facts on the continuous shooting. Compare the above info. I do believe this site is biased. On purpose? By using stats to make one look better? By using untested specs to make one look better? You can make one camera look better and give it a better rating by using just one stat and not using all the stats. You can rate one stat better and increase the rating. Manufacturer specs: you also have to be careful. One company says optimized and the other company says not optimized. Then you find out both are identical. What other specs are not true? Both cameras are amazing. Use both for what you and the camera are best at. Use you cameras system. It amazes me when I read that a person is selling their system and moving to the other company. How can anyone sell a $7000+ system for $5000 and buy a new system for $8000+. A loss of a new camera. Do I hear Forrest Gump. Stupid is stupid does. My sons boss got a picture of mine and blew it up to 3 feet by 8 feet. Then put it in his hotel dining room. This picture was from a 2006 crop camera with a very good lens. If a 2006 crop camera can have such a big picture then any full format will out do it. Go take pictures.
