ENG-7
7. Picture Taking
• Image quality deteriorates near the minimum
aperture opening due to diffraction.
• The magnification refers to the ratio between the
subject’s size and the corresponding image size
on the focal plane. On the distance index, it is
indicated as 1:x.
• To prevent camera shake, using a Remote
Switch (both sold separately) and tripod is
recommended.
• To check the depth of field, press the camera’s
depth-of-field preview button.
Normal Photography
The lens can be used as a telephoto lens for
normal photography.
Closeup Photography
Close-up photos (minimum focusing distance of
0.48m) up to 1x (life-size) magnification are
possible. The minimum focusing distance is the
distance from the subject to the film plane. The
distance from the front of the lens to the subject
(working distance) is about 0.25m.
When focusing, you can give priority to framing
or to magnification.
[Framing Priority]
While looking through the viewfinder and framing
the subject, focus with the AF or MF mode.
[Magnification Priority]
1. Set the lens’ focus mode switch to MF.
2. Set the magnification.
While referring to the magnification scale on
the lens, turn the focusing ring to the desired
magnification.
3. Focus the subject.
While looking through the viewfinder, move the
camera forward or back to find the point of
focus.
4. Touch up the focus.
Turn the focusing ring for fine focusing.
Since macro shots have a very shallow depth of
field, focus carefully to obtain proper sharpness.
