2008年12月2日 拍摄时用脚架和反光板升起模式
这个测试是看看反光板锁起(MLU)对在脚架上用慢快门的帮助有多少。MLU是我买下D700的一个原因，在上次新疆之旅拍了许多脚架上用慢快门的失败之作，一即希望能够找到解决的方法。下列是这次测试的结果，两将100%的截图代表了有用MLU和没有的结果。
有用MLU的：
没有MLU的：
整个测试的画面是这样的：
拍摄是用D700配合尼康的AFS 70-200 F2.8 镜头在200mm照距和F2.8，快门速度是1/6秒，脚架是百诺的C127-n6 配合PHOTOCLAMP的云台。测试在有MLU和没有MLU拍下多将照片，结果和上列的两将一样。
这里清楚看到使用了MLU对脚架上用慢快门拍摄时有明显的帮助。
Holy shit. Now I am convinced I need a MLU digital camera too. Man it makes a difference, are you for real? I guess you are as you stated that you tested it multiple times. Even on a tripod, so it’s the mirror slapping down, the vibration within. My Nikon FE has a loud thud, but since I never enlarge my negative so I never knew it makes a difference even often time I suspect there will be shake. The 2nd picture here shooting some dead leaves close, I did use MLU on my Hasselblad, I think was pretty sharp.

Yes, three frames taken at each setting and the result is the same. Yes, the mirror slapping do have an influence. Of course, this will only shows up in 100%. Which needs a magnifier to be able to detect in film and prints. The MLU thing I am told by a Master shooting Hassebald on a Gitzo tripod. I think if a guy using Gitzo also say that MLU is necessary. We using cheaper brand tripod must needs it.
