easuring just 71 x 86mm
and weighing in at 430g,
this is the smallest APS-C
format lens in the group.
It’s only slightly heavier than the
competing Tamron 18-200mm,
despite having a metal rather than
plastic mounting plate. A space-saving
ultrasonic motor rather than ring-type
autofocus drive helps to shed a
few ounces, but the focus
ring rotates during autofocus.
Three aspherical elements help to
reduce the size, while three Special
Low Dispersion elements minimise
fringing. The optical stabiliser has an
effectiveness of about four stops and
features auto panning detection.

Performance
Sharpness isn’t quite as impressive
as in Sigma’s 18-300mm lens, but it’s
still pretty good. Corner sharpness
is slightly better in the 100-200mm
section of the zoom range.

he larger of Sigma’s two
lenses on test, this one
is physically only 16mm
longer at its minimum
zoom setting, but stretches rather
more at the long end of the zoom
range. It’s also 36 per cent heavier
at 585g. Like its smaller sibling,
the construction employs Sigma’s
Thermally Stable Composite
material, which is highly resistant
to size fluctuations during
temperature changes.
Again, there’s a metal mounting
plate but no weather-seal ring.
Upgraded glass sees the inclusion of
four top-grade Fluorite Low Dispersion
elements, along with one SLD element.

Performance
The AF system isn’t particularly
speedy and is clearly audible. The
optical stabilizer gives a four-stop
effectiveness. It beats Sigma’s
smaller lens for image quality.

Sharpness
Centre sharpness remains
nicely consistent throughout
the zoom range.

Sharpness
Sharpness is excellent across
most of the zoom range, only
dropping off at the long end.

Fringing
Short 2.29 Long 2.51
Fringing is worse at max zoom
than Sigma’s 18-300mm.

Fringing
Short 2.87 Long 1.64
Colour fringing is respectable,
especially at mid to long zoom.

Distortion
Short -2.81 Long 2.01
Pincushion is a bit worse
than Sigma’s 18-300m.

Distortion
Short -2.76 Long 1.27
The lens controls pincushion
distortion well.

Build &
handling

It’s not the sharpest
tool in the box but
gives good overall
performance through
its zoom range and is
pleasingly compact,
as well as being
attractively priced.

Handling is slightly
impaired by the focus
ring rotating during
autofocus but this
superzoom offers the
greatest zoom range
with little compromise
in image quality.
