明星编辑小时后大家都玩过FC上的魂斗罗吧？相信那条经典的秘籍大家都还记得：上上下下左左右右ABAB。然后，我们就带着30条命开始疯狂的杀戮之旅。而今，数码单反相机之中，竟然也出现了类似的隐藏秘籍。不过这次调出来的不是30条命，而是更加宽泛的ISO设定。
用过E-300的玩家可能都有这种感觉，为什么它的ISO设定那么少？其实也不少了，E系列数码单反上的ISO值已经可以满足我们日常使用的要求。不过，看着别人的数码相机能把ISO设定到6400,难道你不想试一下么？其实奥林巴斯早就给我们预留了这样的机会。
其实笔者也是前两天浏览网页，无意中才看到的。消息发布者给出了详细的操作说明，原文如下：
First you need to get to the diagnostics screens
As others have posted:
1.open CF door
2.press 'play' and 'ok' button at the same time and then release them
3.then on the 4 button keypad press 'up' 'down' 'left' 'right' press the shutter button and then the 'up' button again.
at this point you should see a screen that says "page 1" and a bunch of other stuff.
Now for the fun stuff (a little unscientific aswell):
1.To get to the Test Mode goto page 3 by pressing the 'iso' button, it should now indicate "page 3"
2. Then press random buttons along with the 'ok' button until the "Test" screen pops up. (you'll know it when it does and it will). Once you have gotten the test screen to pop up once all you need to do is press "ok" and you will go back to it.
-------------------------------------
So far I have found that I can get the camera into iso=50, 60, 80, 125, 160, 250, 320, 500, and 640. and when you close the CF door those setting are retained until you change the iso value you can even turn the camera off and it will stay.
To get ISO 50 for example scroll to 'prg 10' and then press 'ok' it will flash on the screen and then shut the CF door and viola usable ISO 50 until you change iso. To get other iso values goto 'prg 10' and then just go over to item and change that value to 1=iso60,2=iso80 and so on.
Obviously this is not what you would want to be doing while out taking pictures but if a situation calls for a very low ISO there ya go:)
There are a lot of other things in there (most do nothing) but there is a complete reset by holding certain buttons but who knows how much of a reset "full reset" is so i wont provide that one.
This goes to show you the the firmware is there from the E-500 as far as iso but deactivated.
Enjoy!
下面则是笔者根据上面的内容翻译出的方法：
2、打开CD卡舱盖，
3、同时按住“浏览键”和“OK”键，此时，我们就可以看到相机的版本号了，
4、接着按照上、下、左、又的顺序按机身后面的四个方向键，
5、再按一下快门，
6、按方向键“上”，
7、再按“下”，也就是ISO键，
8、同时按快门+OK键，直到显示出TEST菜单，
9、选择prg10,item=0的时候就是ISO=50，item=1的时候就是ISO=64，以此类推，
10、选择好数值后，按OK确定，然后关闭CF卡舱门，调整完毕。
调整后，只要不重新设定ISO值，那么都将维持你所选定的数值。
怎么样？有点意思吧？只要你高兴，还可以选择ISO=2000、3000、以及更高的数值。当然，发布者也给出了手动模式下ISO=50和ISO=100的照片对比。
ISO 50 ISO100
目前，这个调节方法对于E-1、E-300、E-500、E-330都有效。只是E-330的调节方式稍有变化：“同时按浏览键+OK键”的操作要变成“同时按MENU键+OK键”才行。相信不少用过奥林巴斯C-5050等数码相机的玩家一定看出来了，这些操作其实是帮我们打开了奥林巴斯相机隐藏的工厂模式菜单而已。其中的“TEST”项目，就是帮助进行相机各种性能测试检查的。只是那个“上下左右”的操作实在容易让人联想到当年那个红极一时的秘籍罢了。不过，相信对于奥林巴斯数码单反相机的用户来说，这条秘籍也算得上大有用处啦！
那么，知道了这个，你还想知道如何看E-系列数码相机的快门使用次数么？那不妨往下接着看。
