9.Taking Hand-held Close-ups
Close-up shots are more prone to be affected by
camera shake than with normal shooting. The
Image Stabilizer's corrective effect is therefore
less during close-ups than during normal shooting
even with the same degree of camera shake.
The depth of field also becomes very shallow with
close-ups, and moving forward or back even
slightly will throw off the focus.
When hand-holding the camera for close-up
shooting, minimize camera shake and blurred
focus with the following techniques:
Hold the camera firmly
As shown on the right, hold the camera firmly so
it does not move while shooting.
Use AI Servo AF
For close-up shots, set the camera's AF mode to
AI Servo AF. Using autofocus is recommended.
The AI Servo AF mode can minimize blurred
focus during close-up shooting.
For details, see the camera's instruction manual.
Place both elbows on a steady surface such as a table.
Use your knee to support
an arm holding the
camera. Lean against a steady
object like a wall.
