I no longer have a 35-105 or a 65-200 zoom to check, but I suspect that
they do not change length when zooming; I have at least two one-touch zooms
(Tamron 80-210, Tokina ATX 80-200) that do not change their length when
zooming. Note that the 75-150 Zuiko also has internal zooming, and thus
does not increase in length.

I checked my OM System Lens Handbook. It gives a length for a
specified zoom for the 100-200/5, 28-48/4, 35-70/3.6 and 4. It just
gives a length for the 85-250/5, 35-105/3.5-4.5, 75-150/4, and
65-200/4. Not consistent, I guess, since the 35-105 and 65-200 are one
touch zooms.
