It helps me if you get yours at either one.
feel like overnighting on Mt. Whitney, so I left these lenses
in my freezer at 0º F (-20º C) for 24 hours. I kept them in
ziplock bags to avoid condensation when I took
old days lenses were lubricated with grease that froze solid. This
prevented them from focusing. That's why I tried this.
The good news is these lenses all work. They were fairly similar.
AF speeds were unchanged. The zoom rings got stiffer. Manual focus got very
stiff on the Tokina.
There isn't much
difference between these. They all work fine at 0ºF, at least for
the short while I tried them.
A little stiffer
and perfectly usable. You can no longer flick it with one finger
from one end to the other.
Stiff. About twice as much drag as at room
a little stiffer than before, which is still lighter than the Sigma
and Tamron at room temperature.
was slower on my D70, but I also froze the D70 at the same
time. The other lenses were tested on a room-temperature D200.
Unchanged, which is still slow even at room temperature.
stiffer, slow but usable. Of all the lenses this is the only one
that might be stiff enough to worry you. If it's
this cold you'd better be in gloves and want a stiffer action
to prevent knocking it by accident on the ski slopes.
As stiff as the zoom
a little stiffer, which is still reasonably light.
Stiffest of the bunch and still quite usable.
than room temperature but perfectly usable.
It was so light to begin with that it's now
about as firm as the other lenses were at room temperature.
