Hard-to-autofocus subjects
The autofocus system of this camera is highly
precise, but like many other autofocus cameras,
the system is not almighty and may not properly
focus on certain subjects. In such a case, use the
focus-lock technique on a subject near and
equidistant from the actual one. The subjects which
are hard to autofocus are:
1. Black objects like hair, etc. which are hard to
reflect light (infrared).
2. Wire netting, latticework, iron exercise-bar, etc.
3. Flickering light sources such as neon signs,
fluorescent lamps, TV images, sunlight coming
through the trees, etc., or any subject illuminated
by these light sources.
Glass, mirrors, car bodies, etc. which are glossy
and reflective.
Fast-moving objects like trains.
Water jets, surface of water, smoke, flame,
fireworks, etc. which are formless.
