5.0
Owner's of the Leica Digital Camera 18450 gave it a score of 5.0 out of 5. Here's how the scores stacked up:
AUTOMATIC DISTANCE SETTING / AUTOFOCUS
With the AF mode set, focusing is performed automatically when the shutter
release button is pressed to the first pressure point (1.8), i.e. the distance is
measured, set, and locked (see also p. 147).
• To indicate a correct and locked AF setting,
- the frame color changes to green,
- up to 9 green rectangles appear in the case of 11 area metering
(see p.123),
- the green focus status LED (1.19) lights up, and
- an acoustic signal is generated (if selected, see p. 123).
Notes:
• AF settings are locked together with the exposure settings (see p. 126).
• In certain conditions, the AF system cannot set the correct focus, e.g.
– if the distance to the targeted subject is outside the available range,
and/or
– if the subject is not suciently illuminated (see next section). ‘
To indicate such situations/subjects
– the frame color changes to red,
– in the case of 11 area metering, the display changes to a single red
frame, and
– the focus status LED (1.19) flashes.
Important:
The shutter release button (1.8) is not locked, regardless of whether a sub-
ject is correctly focused or not.
AF ASSIST LAMP
The built-in AF assist lamp (1.2) extends the AF system’s operational range
into low light conditions. With the function activated, the lamp lights up
automatically in such situations whenever the shutter release button (1.8) is
pressed.
In the menu, select AF-Assist Lamp (3.6), and in the submenu the desired
setting.
Note:
The range of the AF assist lamp is approx. 4 m/13 ft. Therefore, in low light
conditions, AF operation is not possible for distances beyond this limit.
