f9: Focus Ring Rotation Range

[Non-linear]

The focus distance changes by a large amount when the ring is rotated rapidly and by a small amount when the ring is rotated slowly, without regard to how far the ring is rotated.

[90°]

Choose how far the ring must be rotated to go all the way from the minimum focus distance to infinity. To take focus from the minimum distance to infinity when, for example, [90°] is selected, the ring need only be rotated 90°. Larger values permit finer adjustments.

[Max.]

Taking focus from the minimum focus distance to infinity requires rotating the ring the maximum distance permitted at current lens settings.
