小弟用緊D3s,今日去影相發現,當光圈收至4.5或更細時,影白色時相片上有兩個黑點,光圈越細點越深色,試過幾支鏡都係咁情況,已用機內除塵功能都係咁,請教各位師兄,係感光原件有塵定係發霉呢?有咩辦法解決呢?謝謝~

感光原件有塵

Check the reflector mirror first.

夾硬吹走佢啦, 我都係用手動5秒曝光將個反光版彈出來, 然後用氣泵吹走.

yes, dust on the sensor.

make sure you are in a dust free environment, and use a nice powerful air pump to blow away the dust.

keep in mind if you don't do that properly, you will actually blow more dust inside that mirror house and sensor.

Also, NEVER touch the sensor.

btw, use the mirror lock up function on D3s. coz if anything still around the mirror and it comes down, it will damage the mirror and sensor.

If you know about how much does it cost to place the D3s sensor, you will not wanna mess around with it unless you are absolutely sure what you are doing =D

Use mirror lock up for cleaning. Never use M mode or Bulb to release the shutter. The sensor will act like a magnet to dust when it is on. Also, you don't want the mirror to go down suddenly when your tip of blower is inside the chamber.
