TEST

at this distance, the magnifi cation ratio
comes up to be 1:8. This can be onsidered
fairly decent, given the wide focal length.
The lens accepts 77mm fi lters and the
the front element does not rotate while
focusing. This is quite handy for those
wanting to shoot landscapes along with
circular polarisers.

Handling
We coupled the lens with the Alpha
A77M2, and the combination felt quite
light and well-balanced. Despite the fact
that the lens weighs only 360g, it feels
pretty sturdy. However, a polycarbonate
barrel construction makes it look and feel
quite average.

T


his lens is not a new launch at all,
the roots of the Sony DT 11–18mm
f/4.5-5.6 lens go as far back as the
year 2005. Tamron had launched
a 11–18mm lens during the PMA
show in those days, and just after about
a year, Minolta merged with Sony. They
came out with a new lens that matched
all the specifi cations of Tamron’s version
for the Minolta mount (now the Sony
A-mount). Sony brought the same lens
back to the market with the A100, under
their brand name, of course.

Features
If you have a Sony A-mount DSLR, then
this is the only wide angle offering from
the manufacturer. The lens features four
special elements, out of which three are
aspherical and one is an ED element.
Overall, the lens consists of 15 elements
arranged in 12 groups. While the lens
offers a 7-bladed aperture diaphragm
unit, it doesn’t really make much of a
difference as wide angle lenses offer larger
depth of fi eld.
At all focal lengths, the lens offers a
minimum focusing distance of 0.25m, and
