DCS Meter Exposure for Manual Lenses

Hi.

I have a DCS/c and a manual lens. Actually it's a Nikon lens mounted on a Canon mount using a Novaflex Nikon to EOS adaptor.

Is it possible to use the Camera's internal exposure meter with lenses mounted in this fashion. Because of the interceding adaptor, there's no connection between the lens and the camera, as there would be were I using a Canon auto-focus lens.

How can this be done? It would be nice to take advantage of the cameras center weighted, spot, and averaging meter.

What I meant is that there's no electrical connection between the camera and lens.

I have a similar setup with my Mamiya 645AFD/Kodak 645M where I use a couple of completely manual non-Mamiya lenses via adaptors. In this case, the camera has no visibility of the lens itself but can measure the amount of light present through the lens.

You'll need to either meter manually and set the camera that way or alternatively compose/focus with the lens wide open and then manually stop down the aperture on the lens and then use the camera's meter. It's pretty simple - 'stop down metering'. Your camera usually measures the exposure at your widest open aperture to get an EV value - this is then used to calculate the appropriate shutter speed for the aperture you've selected to use for the shot.
