我部d 90 A 模式可以set 快門，部機係咪壞左呀？

如果可以set 快門光圈會跳動，例如500份1秒光圈會隨著跳動又影到相曝光正常，咁你要上CS 問問？

ringomov bro already answered you question.

What do you mean by 可以set 快門?

In A mode you can define the Aperture value, and the camera auto adjust the shutter speed for you. It is constantly changing while you frame your composition. This is normal if you see the shutter value is changing.

Is that your case?


If you are doubted, I suggest you try to reinstall the firmware and see if it brings it back to normal. If it still doesn't work, then you can bring that to CS for a check.

Cheers,
