24mm F1.8 EX DG ASPHERICAL MACRO
With an angle of view of 94.5º
an open-aperture of F1.8, and a
shallow depth of field, this super-
wide-angle lens makes picture-
taking a fun experience. Its fast
F1.8 aperture makes handheld
shooting in dim light possible,
making it ideal for architectural,
landscape and indoor photography.
Designed for digital SLR cameras,
it has a minimum focusing distance
of 20 cm (7.9 inches) and a lens-
to-subject working distance of 6.5
cm (2.6 inches), so it is perfect for
close-up photography. The use of
aspherical lens elements effectively
correct all types of aberrations,
minimize vignetting, and provide
superior peripheral brightness.
The rear focus system allows the
use of a Petal-type hood. This is a large-aperture wide-angle
lens that gives photographers
freedom of expression by allowing
them to set the aperture they want
and obtain effects such as beautiful
out-of-focus images obtained with
an open aperture. A maximum
magnification of 1:2.7 and the use
of a floating focus system enable
a minimum shooting distance of
18 cm (7.1 inches), opening up the
enjoyment of close-up photography.
The use of aspherical lens elements
effectively correct all types of
