Setting the Exposure

When taking photographs using TTL metering, no exposure compensation necessary to meter the light coming through the lens.

With TTL, metering, AE (autoexposure) is possible at all focusing distances. Just set the desired picture-taking mode, then check the shutter speed and aperture before taking the picture.

Magnification and Effective f-number

The aperture displayed by the camera assumes that the focus is set to infinity. The acutal aperture (effect f-number) becomes darker (effective f-number increases) This does not cause exposure problems for normal picture-taking. However, for close-up photograph, you cannon ignore the change in the effective f-number.

When you use a handheld exposure meter to set the exposure, you must take into account the exposure factor shown in the following table.
