Verdict
The Sigma AF 18-125mm f/3.8-5.6 DC HSM OS is an interesting lens with a couple of high and lows
which is quite typical for such extreme zoom range lenses. The resolution characteristic is
generally decent - only the soft borders at 125mm may be really objectionable. The vignetting
could be better at 18mm and 125mm at max. aperture but frankly that's also nothing out of the
ordinary in this class. Distortions as well as CAs are comparatively well controlled.
The build quality is on a very high level although the rather odd non-OS mode implementation
is a bit of a faux-pas here. The AF performance is nothing special nor bad either. The OS (Optical
Stabilizer) can give you a couple of extra f-stops in extreme situations but don't expect
wonders - the specified gain of up to 4-stops is unlikely in field conditions. All-in-all a sound
package when taking the competitive pricing into account.
