当我按下景深预览后，在取景器上却看到AE-L（曝光锁定）亮，看不到取景器有任何变化，再缩小光圈，再按，同样AE-L（曝光锁定）亮，取景器图像没有变化，但当松开景深预览健后，有怪声。。拍摄模式P, M, S, A都试过，情况一样。 不知道如何是好，望能帮助解答，多谢！！！

唔應該冇變化，
一按景深預覽之後，光圈會因應用家的設定收細，所以會有聲音。
而且你應該發現取景器會變暗。

按道理系应该一直按住景深预览，光圈会收细，但问题，它现在系放手时，才发出响声，并且，光圈并没有任何改变！！吾知么问题！！

1. Are u using NIKON af, afs lenses...? hope the lens is working OK...?

2. Have u changed the function of the DOV PREVIEW BUTTON....? Press INFO button TWICE (2 times)... on the LCD monitor... bottom of screen , u can see what the current function is.

發覺機有問題最好去nikon服務中心check 吓，好過古古吓。

the lens i used is the 50mm F1.4G, it should be ok..

and i checked the DOV on the info screen, on the bottom right corner, 1st row, the assignment of DOV button shows the right place...

Pressing the Depth of Field button will light up the AEL (in the viewfinder)... this is normal.

There is a very noticeable "click" sound when the aperture is being stopped down.... this is also normal.

Whether this works with 50mm F1.4G, u will have to check with Nikon Mongkok CS Office ... (could be a bug in the old firmware...? or a bug in the newly updated firmware...?)

I only used this "preview function" for a couple of weeks and then decided to change it to "image area" ( FX / DX ) function which is more useful to me.

thank you very much for the reply.....when i have the opportunity i will check with different lens, but I am in Germany now, it is hard to check with the CS office when most people doesnt speak english............but after reading ur reply, i feel relief.....at least the camera seens to be OK.....Thank you so much!!!!

You have set the 景深预览 button to AE-L function, press INFO button twice, the menu shows the preview label, go to set it back la.
