It promises to be the ultimate large-aperture, wideangle
zoom for today’s full-frame mirrorless cameras, but is it?

ot to be confused with
the Sigma 14-24mm
F2.8 DG HSM that
was released in 2018,
the Sigma 14-24mm F2.8 DG DN
is a new wideangle zoom that has
been specially developed and
optimised for today’s high-
resolution full-frame mirrorless
cameras. Whereas the 14-24mm
F2.8 DG HSM (£1,129) is available
in Canon EF, Nikon F and Sigma
lens mounts; the £1,299 lens we’re
looking at in this review is made for
mirrorless cameras that use the E
mount or L mount.
For landscape, architectural and
astronomy photographers, it’s a
lens that lets you squeeze more of
what’s around you in the framethan lenses like the Panasonic
Lumix S Pro 16-35mm f/4
(£1,499) and Sony FE 16-35mm
F2.8 G Master (£1,995), which
are £200 and £695 more
expensive respectively. Sony does
produce a lens of similar focal
length – the FE 12-24mm F4 G,
but this is also more expensive and
doesn’t provide as fast maximumSig ma 14 -24mm

On paper it seems Sigma has
created a very strong product at
an excellent price point where
there’s an obvious gap in the
market. As we all know though, a
lens is only as good as the optical
performance it puts in, so with the
mighty 61MP Sony A7R IV in my
possession I took the opportunity
to fi nd out if the lens is a match
with today’s highest resolution
full-frame mirrorless camera.Made for mirrorless
Compared to the Sigma 14-
24mm F2.8 DG HSM, which is a
brute of a lens, this zoom has a
noticeably thinner barrel that’s
