Setting Aperture.4 - Minolta 35-105MM F3.5-4.5 MD ZOOM Owner's Manual

SETTING APERTURE
The effective aperture of this lens changes as
it is zoomed between 35mm and 105mm. At
35mm, maximum and minimum apertures are
f/3.5 and f/22, respectively; at 105mm, they
aref/4.5and f/28.
TTL (through-the-lens) metering of Minolta
cameras automatically meters for the light
actually passing through the lens. In automatic
exposure mode, such as "AUTO" or "A"
(aperture-priority), "S" (shutter-speed priori¬
ty), or "P" (program) mode, the camera auto¬
matically controls exposure so that no compen¬
sation is required. When using metered manual
("M") mode, the correct exposure reading can
be viewed in the finder; exposure compensation
is not necessary.
In full manual mode (i.e., when using a
hand-held light meter) or for flash photography
(other than with programmed flash), the
aperture should be set after zooming to the
desired focal length. Two aperture indexes are
provided on the lens barrel. The longer orange
index indicates the aperture of the lens when
the focal length is set at the shortest focal
length (35mm), and the shorter yellow index
indicates the aperture when the focal length is
set at the longest focal length (105mm). The
aperture indexes are color-coordinated with the
local-length designations on the lens barrel for
quick reference. When the lens is zoomed to a
focal length between the shortest and longest,
set the desired aperture at the index corre¬
sponding to the nearer focal length.
When using an SLR with a window for
aperture readout in the viewfinder, the aperture
displayed corresponds to the 35mm setting.
NOTE
• Zooming causes a change in effective
aperture amounting to about one half-stop
over the lens' full focal-length range. There¬
fore, to precisely control exposure when
using the AE lock (found on the X-700
camera), compensate for this change before
engaging the lock or do not zoom after
engaging the lock.
