Adjusting the resistance of the focus drive | Leica M165 C, M205 A

Adjusting the resistance of the focus drive

Adjusting the resistance

Is the focus movement too loose or too tight? Does the outfit tend to slide downwards? The resistance can be adjusted individually depend- ing on the equipment weight and personal preferences as follows:

1.Grip the outer drive knobs with both hands and turn them towards each other until the desired resistance is reached during focus- ing.
