VERDICT
The Sigma 20mm f/1.4 DG HSM
is a very sharp lens – ideal for
landscapes, environmental portraits,
architectural photography, shooting
in any cramped spaces and for use in
low light conditions, including astral-
photography. It is on the heavier side but
its ability to shoot in low light should
make up for the weight. Best Buy!
PLUS
- Very sharp
- Almost
imperceptible
distortion - Very good
build quality
MINUS
- Filters cannot be used
- Quite heavy
- No IS (but would
you need it for a super
wide-angle lens?)

KEY SPECIFICATIONS
At f/1.4, darkening at the corners was
evident. Corner darkening reduced
appreciably by f/4. Flare could be
seen in shots that included the sun.
Chromatic aberration was very well
controlled – only a trace could be seen
when we tried hard to look for it.
Overall, a very good performer!
Value for Money
The Sigma 20mm f/1.4 DG HSM Art is
available at an MRP of Rs.73,000/-. This
may sound expensive but don’t forget
that it is a f/1.4 lens. In our opinion, the
price is justi�ied. |SP
