Subject: [Leica] Tri-Elmar focusing

Does anyone know if this lens has to be refocused when focal lengths are
changed?  In some zooms, the lens stays in focus when the focal length
changes.  You focus at the longest focal length, then zoom out to whatever
focal length you want to use. The Tri-Elmar is not a zoom lens, so I'm
wondering if focusing drifts when the lens is set to a new focal length.
