[首發]Nikon D5 暗部對焦測試 (Nikon D5 Auto Focus in very low light)

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.




測試的鏡頭為AF-S NIKKOR 24-70mm f/2.8E ED VR
I uses AF-S NIKKOR 24-70mm f/2.8E ED VR on D5.






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.



抬燈關掉之後, 箱子裡面根本一片漆黑
It's completely dark in the box when we power off the lamp.



暗部對焦測試影片
Tesing video

D4S是CF卡與XQD雙卡槽




D5則分為兩個版本

雙XQD版




雙CF版





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.

默默覺得1DX的比較快XDDDD

影片中聽起來差異感覺沒有很大!?

不知實際如何?

感覺發的很倉促, 搶業界第一嗎?  我要看高iso畫質, 還有DR測試阿~

都是買不起的玩具...

還是找α7S II 對焦速度也不一定會輸

QXD實在是貴到靠北邊了

草,暗黑環境對焦已經很困難,還對得這麼快又準
服了........

這對焦性能 個人只能望其項背了

D5太強大了吧...  未來CANON陣營不知道會怎麼應付

買不起的玩具...

還是帶著D700繼續再戰十年吧XD

D750+1代24-70,繼續再戰。。。
除非我中樂透。。。
