| Use of lenses on a "transitional body" | ||
|
In the photo at left, a non-AI lens has been mounted on an F4. Normally,
the aperture ring on the lens would interfere with the the metering tab (center of photo)
but the tab has been released by pushing the small button just below it. In this
situation, through-the-lens metering is possible but it must be done stopped down. Click on either photo for a larger image, then use the browser's Back button to return here. |

In this photo, the lens has been converted and can be mounted on the body
with the tab in the down position. Thus, the metering tab will move with the aperture ring
and full-aperture metering is supported. Different bodies will provide different
capabilities when used with converted lenses. Look up "AI-modified lenses" in
your body's instruction book for details. Click here to return the Compatibility Table. |
