How Often Does a Leica Rangefinder Camera Need an Alignment?

A Leica rangefinder does not need alignment until you drop it. But it would be best if you got it checked after 6 months.

The Leica M6 rangefinder camera has a built-in autofocus system that uses a contrast detector sensor. This works by measuring the light reflected from the subject being photographed.

It then compares this measurement against the stored information about what the lens should focus on. If the two don’t match, it will automatically adjust the lens so that they do.

DIY Rangefinder Adjustment

You can fix this yourself. You need to adjust the focus ring on your lens. Focus on something far away and then move the focus ring until the subject is sharp. Then move the focus ring back to infinity and lock it there. This should hold the patch in place without drifting.
