Focusing speed?
- The focusing angle must be optimized, too small is very critical in
focusing, too large will be very slow. The Zuiko 35-105 is just too large at
the wide end
- Focusing friction, suitable damping is need, not too much and not too
little. Like some Lei*a R lens I have tried, they are too tight and focusing
angle is also too large, like the 180/2.8 APO.
Of course it will depends on how you use the lens, if you put on the tripod
for landscapes, there will be no problem.

You have identified one of the things I feel very strongly about. I have
had lenses in the past where you had to turn them so far to focus from one
point to another that if the object being photographed were not stationary
like a mountain, it was impossible to turn the focusing ring fast enough to
catch the shot.
If you ask me, you should be able to focus all, or nearly all of the entire
range without disconnecting your hand. I would rather have a lens that
focuses a little bit too fast than to have to twist the barrel a dozen
times to get from one end to the other.
