Mirrorless Camera ISO Signal/Noise Shootout: NEX5, NX10, E-P2, E-PL1, GF1, G2, GH1

Design and Methods:

The goal here was to show the relative potential of these systems, hence I will present only RAW conversions and not in-camera JPEGs. There are many sites with excellent in-camera JPEG comparisons.
All images were made using Sony, Samsung, and Panasonic (14-45mm) kit zooms at f/5, which was chosen because it represents a setting of good center sharpness with adequate depth of field for all systems.
All kit zooms were used at their widest setting, and the subject distance was constant. The Panasonic lens at 14mm actually has a slightly wider angle of view than the Sony/Samsung at 18mm, but the reverse is true after Lightroom correction of barrel distortion. For practical purposes, the diagonal angle of view was fixed.
Since the purpose here was to look at sensor rather than lens performance, only center crops from the within sharp focus portion of the image were used for comparison.
To present a valid comparison of detail relative to noise at any given ISO, exposure times were matched for all systems as follows: 1) ISO 100: 2s; 2) ISO 200: 1s; 3) ISO 400: 1/4s; 4) ISO 800: 1/4s; ISO 1600: 1/8s; ISO 3200: 1/15s; ISO 6400: 1/30s. Lighting sources were kept constant.
Each shot was done in triplicate to ensure reproducibility.
All system settings were image stabilization off, self-timer, sturdy tripod.

給喜好觀察高ISO的人參考,目前無反光鏡系統相機之高ISO能力呈現。

片幅大小的優勢很明顯

以iso800來看,NEX-5的雜色塊還不是很明顯,但其它m43機種已經有很多雜色了。
ISO 比較大家心裏都有個底了吧!不就是跟片幅有關...
另外,
色彩是看人喜好、
畫質跟鏡頭較有關..

比較想知道的是「對焦速度」的比較!
網路發言嘛... 多是隨便說說!別太認真..

速度跟鏡頭有關,但是對焦不只有速度,還有對焦能力,目前對焦速度與暗處對焦能力應該是M4/3略高一籌。

精確一點來說,應該是pana家的M43機~

有嗎?
我覺得 NX10 看起來跟 m4/3 一樣慘阿
難道說 NX10 的片幅跟 NEX-5 不一樣

NX10和m43比還是好一點點,跟NEX-5比就差了。

只能說samsung還要加油

話說NX10沒什麼人討論 是因為剛出嗎?

NX10比NEX早出...
沒什麼人討論的原因有兩個
一來它是韓國貨,台灣人有很高比例是拒買韓貨的(包括我個人在內)
二來是NX10表現實在很差,引不起興趣
