嗯，我有看過KenRockwell寫的這篇文章，但是因為沒有親自體驗就不敢宣稱。不過他似乎有提到高於1/1000就無法保證準確度。
At higher speeds, you can get to about 1/8,000, but what happens at these higher speeds is that they can become inaccurate, and your exposures will vary. That's why Nikon didn't specify the FE for speeds above 1/1,000.
另外KenRockwell也表示fe的夜間長曝也是挺方便的，A模式快門的最長曝光時間可以達到63分鐘。但長曝時間隨著溫度與按下快門前的進光量而有差異。
Out of curiosity, I loaded fresh A76 cells into an FE set to ASA 50 and, with the lens cap on in AUTO, pressed the shutter.
The shutter stayed open for 63 minutes, and then closed at ISO 50. Whoa!
I tried it again set to ASA 400, and the FE stayed open for 3 minutes and then 17 minutes. It will vary by temperature and the amount of light to which the FE was exposed a little while before you started the exposure. Remember, the FE is analog, and it's the leakage currents which are defining the long exposure times.
FE真的是便宜好用的相機首選！大推！
