D750反光鏡震動與鏡頭關係

相機的抗微震

由d7000開始進入高密度畫數時代就開始了

當時就是一堆人以低畫數時代的想法為基準

沒有把安全快門拉高,導致微震一堆

把整個畫面都拍得超軟...

而利用拉高快門去排除,就是最簡單的方法

這個是困擾的問題,但不是不能解決的問題

d800系列,除了d810好一點外,d800,d800e都很慘

但大部份的使用者也都排除了這個問題

如果連裝在800mm上都可以解決微震的問題了

若在200mm以下還排除不了,是真的早點遠離反光鏡的世界比較好的

省得造成自己的困擾

你先仔細看這測試再說吧,看看810搭70-200 f4 開VR的影響,再比較5DSR
每台型號的反光鏡設計和表現可以不一樣的,不一定要離開反光鏡世界,但離開也不失為一個好選擇

Problematic handheld VR results

We actually undertook this massive study because we found many problematic, blurred shots taken handheld with the 70-200mm F4 VR and 300mm F4 VR on the D810. Nevertheless, after our massive tripod study, we knew we needed to verify that what we were seeing was borne out in handheld, controlled studies.

We actually undertook this massive study because we found many problematic, blurred shots taken handheld with the 70-200mm F4 VR and 300mm F4 VR on the D810. Nevertheless, after our massive tripod study, we knew we needed to verify that what we were seeing was borne out in handheld, controlled studies.

So that's exactly what we did. We present a few of the salient results in the rollover above, showing the results from problematic shutter speeds (~1/50s to 1/160s) for a few lenses with and without electronic front curtain (EFCS).

You can see the results can be shockingly poor in Single Drive mode with VR on ('no EFCS'). We shot EFCS hand-held here in Mirror Up mode (the only mode it's available in), with a 1s exposure delay. That required us to press the shutter button once to lock up the mirror and shutter, then press it again to initiate a 1s exposure delay (so that pressing the shutter button did not blur the image) after which the shot was initiated electronically. While that led to tack sharp shots, it is, frankly, a ridiculous way of working. Yet it is necessary to get sharp shots with these lenses at these shutter speeds with VR on.

That's unfortunate, because it could've been solved had Nikon made EFCS available in all drive modes, not just Mirror Up mode, combined with short, user-selectable delays - shorter than 1s. Ideally, we'd press the shutter button once to lock up the mirror and mechanical shutter,

好像沒那麼慘吧?還是我比較幸運沒中雷?

D750 + 200-500 f 5.6 VR

300mm ; f5.6 ; 1/250s ; iso 5000 ; VR on ; Handheld ; Af-C mode

真的低要求就不會用200-500了,用副sigma/tamron的150-600不是更便宜更長更輕鬆嗎?甚至用rx10就好了
拍出鏡頭應有的表現才對得起花了的錢對不對

唉!小弟最該死的就是原廠情結太重了!
買了這麼貴的鏡頭,無奈技術不佳,卻無法發揮它該有的表現,真希望有機會能跟大大您多加學習!

不會喇你過謙,說來慚愧,我已轉用只有全幅1/4的小底,對好全幅用家來說不值一提
爛片一張iso6400滿渣的不要把你嚇跑就好

你只拿你想看的一部份來看

google的翻譯是這樣說的,也許翻錯了也不一定,反正我的英文不好,至少應翻的比我好

"當兩個攝像機設置為默認,單驅動模式,尼康D810 優於佳能5DSR 。但是,將佳能轉換為“靜音拍攝”,我們發現5DS R可以趕上 D810,甚至在IS開啟時略微超過它,特別是在較慢的快門速度(〜1 / 30s)時,D810傾向於受苦。開啟VR並不能幫助D810; 事實上,情況變得更糟,大概是由於尼康在某些鏡頭上的VR系統與鏡子/快門驅動之間的寄生相互作用。有趣的是,我們沒有看到這個問題,所有的尼康鏡頭,所以你的結果可能會有所不同。此外,尼康的“安靜”模式並沒有特別的幫助像佳能的“無聲”模式幫助5DS R."

這個靜音拍攝,應就是n家的q快門




事實上是

只要有反光鏡,就別想排除微震及移焦需較正的問題

如果無法以技術克服,那就別玩反光鏡系統

要拿其他的相機來比,又會進入品牌之爭,這也實在無聊。

要抗微震

N家目前不妨試試d850

不過就算是d850,一樣有微震

意思是,這就叫更銳?

拿出別家的設備要來n家踢館前,麻煩挑一下好一點的

謝謝翻譯,跟你看的重點不同,看測試樣張更清晰
