我一個原先用5D2的同事，最近換了5D3，然後給我看這段影片，說5D3的高ISO很棒。

5D Mark II vs. 5D Mark III vs. D800

同ISO下，D800比5D系列都還要亮，雖然更高ISO看起來EV拉過高導致雜訊一堆，但是低ISO下畫質還不錯，所以我回他實際應用，D800錄影可以用較低ISO應付5D3較高ISO，這樣曝光可以差不多，但他似乎不表認同，不過我並不否認5D3高ISO表現滿不錯的。

GH2 VS NEX7

無意中搜尋看到此篇，供大家參考。

測試順序有三個：

In the first sequence the 720p50 mode of the GH2 (V1.1 with 17 Mbps) is compared to the 1080p50 mode of the NEX-7. The section of the GH2 video was subsequently scaled up to 1080 lines. The shutter speed was set to 1/100s. The second half of the sequence contains a relatively swift swing as panning for the passing barge, which clearly benefited from the higher frame rate. The aperture was set at F5.0 on the GH2 and to about F4.5 at the NEX (due to its lower ISO sensitivity).

In the second sequence the 1080p25 modes (each camera with 24 Mbps) are compared. The shutter was set to 1/50s, aperture F7.1 at the GH2 and appxoximately F6.3 at the NEX-7.

In the third sequence the 24p cinema mode of the GH2 (V1.0 wit a "mild" 32 Mbps patch) is compared to the 1080p25 mode of the NEX-7 (24 Mbps). The 24p video is sped up by 4% in order to preserve a smooth rendering without the sporadic inserted frame repetitions when rendering at 25 fps or 50 fps. The two sequences were cut to one another such that, in the middle part they are in about the same time.
