Notes:
1. All focus detection operating ranges are approximate.
2. If your subject is outside the focus detection range, the LED focus-impossible
warning indicator (x) or far-focus indicator (◄) will light up inside the DX-1
AF Finder. In this case, turn the prime lens’s focusing ring to less than
infinity (<»); the distance set now becomes the maximum shooting distance
of the prime lens’ focus detection range, so its focus detection range from
maximum to minimum is correspondingly decreased. You can then focus on
the subject even if it falls outside the range tabled.
For example, when using
50mm f/1.8 as the prime
lens, its focus detection
range changes as in the
following diagram.
