Focus point and AF sensor position
(Schematic diagram)
8. [CONF.] AF Check
[Required equipment] Collimator designed for auto focus, Focus master lens
[Preparation] Setting “Test mode”
[CONF.] AF position (by using FI (Focus Indicator) in viewfinder)
1) Set the body at “Test mode”.
2) Set the focus mode switch to “MF” and attach the focus master lens onto the body.
3) Select the focus point in the viewfinder by four way control key and focus point mode switch
(SEL), and then set the body at the collimator with aligning the selected focus point with
the chart of Collimator.
[NOTE] The focus sensor and the line of chart should cross at right angles.
4) Turn the focus ring to the right end, and turn back it gradually until FI lights up and read
the scale of focus master lens. (A) Follow the same procedures from left side. (B)
5) The center point of A and B = (A + B) /2 should be within a range of
−
0.07 to
+
0.05 mm.
(
−
: Back focus,
+
: Front focus )
6) After the confirmation is done, reset the body.

6) Turn OFF the main switch once.
NOTE: When CF is set at “CF17-1”, the shutter cannot be released.
After the confirmation is done, reset the body as follows.
1) Reinsert the battery into the camera.
2) Turn the main switch ON, and make sure that the shutter cannot be released with
blinking “Av - -“ on LCD when attached lens is set the lens aperture ring at manual
position. (CF17-1)
By changing the metering mode while setting the test mode, desired focus sensor can be
selected as follows.
Multi-segment metering: Vertical sensor and Horizontal sensor
Center-weighted metering: Vertical sensor
Spot metering: Horizontal sensor
