期盼已久的Nikon D5
終於在2016年的CES展現身, 有多項性能讓大家眼睛一亮
除了高達328萬的ISO之外, 每秒14張的連拍, 以及新一代的對焦系統與-4EV的暗部對焦能力
It's been another 4 years passed, Nikon launched new D5 in 2016 CES.The specification of Nikon D5 is amazing, 3280000 high ISO, 14fps, new auto focus module with -4EV capability.
今天, 我們要測試Nikon D5的暗部對焦能力到底有多強
也藉由跟上一代Nikon機皇D4S的比較, 了解D5進化多少
爬了爬文, 似乎還沒有人做過D5的暗部對焦測試, 所以這邊我們用中英文雙語書寫
讓更多網友可以看得懂
We're going to test the auto focus system on D5 in a very low light environment. Hope this test helps people to know the improvement of Nikon D5. It's because I don't see any other people did this test on D5, I decide to post this article in traditional Chinese and english.
被測物是一台工廠賽車和一台仿賽車的模型,
後方橘色的是HONDA RC212V工廠賽車, 前方藍白色的是SUZUKI的GSX-R1000仿賽車
The auto focus targets are motorcycle, one is HONDA MotoGP RC212V in repsol orange and the other is SUZUKI GSX-R1000 in blue color.
我們準備了一個箱子, 把兩台模型放在箱子的最底部
橘色HONDA車的車頭向左, 藍色SUZUKI的車頭偏向前方
I prepare a deep box and put two motorcycles in the bottom of the box. Respol orange motorcycle is parked toward left, GSX-R1000 blue is parked toward me.
測試方式很簡單, 鏡頭焦段設定為70mm, VR關閉
對焦方式為AF-S, 對焦點為AUTO
關燈後對焦橘色一次, 藍色一次, 橘色一次, 藍色再一次
全部四次對焦, 看到底有幾次正確合焦
Testing method is very simple. Zoom the lens to 70mm, disable the VR, set AF-S mode and use all the focus points.
Turn off the light, auto focus on orange bikes, then blue, back to orange, then blue. 4 times trial.
新加入的14fps高速連拍, 讓Nikon在反光鏡驅動機構上做了改良
比較一下D4S和D5的快門聲吧
Nikon making new mechanism for the 14fps high speed continuous shooting. The shutter sound is slightly different then the old D4S.
