还是佳能好看!

线条简洁流畅,有美感.

尼康这个,,,,,,,真丑

楼主辛苦,加分5

1DX 外形比较简洁，D4比较粗犷

关于对焦，尼康官网上是这么解释的
Faster and more accurate AF with 51 focus points

The 51 focus point AF system built into the D4 utilizes the new Advanced Multi-CAM 3500FX autofocus sensor module for faster, more accurate autofocusing that performs extremely well under dim lighting.
The 15 focus points at the center of the frame are cross-type sensors that detect phase differences both horizontally and vertically. All 51 focus points are fully functional when lenses with a maximum aperture of up to f/5.6 are used, and the cross-type sensors make the most of this capability. Precise focus can be quickly acquired with autofocusing using all AF NIKKOR lenses, even under lighting as dim as −2 EV (ISO 100, 20°C/68°F), the level at which the scene through the viewfinder can just be made out by the human eye. What's more, 11 focus points (five at center with an additional three to each side) are fully functional when lenses with a maximum aperture of f/8 are used. This enables very precise focus acquisition with sports photography and the like when super-telephoto NIKKOR lenses are used with a teleconverter (2.0x) at a combined aperture value of f/8.
In addition, adoption of a new algorithm enables faster autofocus initiation for even more certain and sharper capture of defining moments especially necessary when shooting sports scenes. The new high-speed AF system also supports high-speed continuous shooting at approximately 10 fps* in FX format with AF and AE tracking.

*Measured according to CIPA guidelines. Value with shooting in AF-C autofocus mode, [S] or [M] exposure mode, shutter speed of 1/250 s or faster, all other settings at their default values.

翻译过来大概意思是共有51个对焦点，其中位于中心位置有15个十字对焦点，全部51个对焦点都可用于最大光圈只有f5.6的镜头，其中有11个对焦点（中间5个，两边各3个）可以用于最大光圈只有f8的镜头，全部51个对焦点在ISO100、摄氏20度的情况下都可以在-2 EV 的光照条件下精确快速对焦（此光照条件是肉眼通过取景器能分辨出物体形状的极限）。
官网上还举了个例子，当拍摄体育比赛时，用了望远镜头+2X的增倍镜，这时镜头组合的最大光圈就只有f8,这时这11个对焦点依然可以使用自动对焦。

如果官网上的话没有水分的话，个人认为这个对焦系统相当给力。

d4还没d3好看呢。
1d系列的真漂亮啊~

对焦差一点

嘛，都是定位问题～反正价格会有区别的～还是支持NIKON出新机= =+大家都要给力呀～不然吾辈可不升级器材了=w=

两款我都喜欢，有银子两个都要哈哈哈，，，

单就硬件指标来说，佳能1DX全面压制尼康，连尼康一贯领先的对焦系统这次也被完全超越，更不要说双核、三核了，悲哀啊！

也许会有D4X
