Without T T L Metering

A t close ranges (reproduction ratios greater than

1:10), the amount o f light reaching the film decreases

as the extension between the lens and f i l m plane

increases. When non-TTL measurement is used for

this range, the result is underexposed photographs

unless compensation has been made for this decrease.

The table at the right gives the exposure factors (com-

pensation values) w i t h exposure increase in f/stop for

non-TTL measurement at reproduction ratios greater

than 1:10. The table at the right is for use when

various extension equipment is attached*.

To calculate the necessary correction in shutter speed

rather than in aperture value, multiply a given ex-

posure factor by the exposure time. For instance,

if the normal exposure at a 1:4 reproduction ratio is

1/8 second, the correct shutter speed is 1/8 x 2 =

1/4 second.

* When you use the lens by itself or attach a teleconverter, such

as the TC-301, exposure compensation is not necessary.
