"Where exactly are the shutter curtains (D40X)"


New Minas, CA
          

Please excuse what may be a naive question. With a lens off and the mirror locked up a cleaning swab can be applied directly to the sensor (or more properly) the filter above the sensor. So where is the shutter itself? Between filter and sensor?

I am presuming the shutter is mechanical with front and rear curtains as opposed to a completely electronic shutter. If that presumption is wrong, then could someone explain how an electronic shutter works and what that means for rear curtain flash modes.

Thanks very much

I think the shutter is between the mirror and the LP filter. The filter itself is right next to the sensor, so the shutter can't be between them. The D40X does indeed have a mechanical shutter, hence the comparatively low 1/200 sync speed.
D40 & D50 have a mechanical shutter which (if I understand it correctly) never goes faster than 1/200 or so, anything faster is handled by the electronics of the sensor. They have a quoted sync speed of 1/500, and won't go faster with a dedicated flash, but if you're using a non-dedicated flash the D50 (and, I think the D40) will sync all the way up to 1/4000.

The shutter curtain is just to the lens side of the bayer filter, well behind the mirror. The reason you don't see it is that the locku operation is specifically for cleaning the sensor, thus the shutter has to be open. It's much easiser to see on a film camera, especially from the film chamber.

or, if you're feeling brave:
turn off the camera and take off the lens. Lift up the mirror and look where the sensor should be. You'll see the shutter.
Doing this can be risky because you can allow dust into the camera and you might get fingerprints on the mirror.

The shutter is behind the mirror when the mirror is in the down position. When the mirror is raised up (viewfinder will be black)the shutter will be open & the bayer filter & sensor behind it will be exposed. If I remember correctly the D40/X do not have a mirror lock up feature. If the camera has a mirror lock up feature when the mirror is raised you will see the front of the shutter. DO NOT EVER TOUCH THE SHUTTER (very easy to damage). When the shutter is held open you will see the bayer filter & the sensor behind it. Hope this helps.
Best Regards,
Marty

The D40x does have a mirror lock up position. It is accessible from the set up menu.

The D40x doesn't have MLU option for taking pictures which is what Marty was referring to. If you lock up the mirror for cleaning, which is what the D40x menu option is for, then the shutter is open so you don't see it. Marty was saying if the camera had MLU for picture taking, then locking up the mirror in that case would show the shutter. But D40x doesn't have this feature, so you can't do it.
