The SIGMA 4.5mm f/2.8 EX DC HSM, is the first circular fisheye lens exclusively for use with APS-C size digital SLR cameras.
This autofocus circular fisheye lens is designed exclusively for
digital SLR cameras with an APS-C size image sensor. It produces
circular image with digital SLR cameras.
The minimum focusing distance
of 13.5cm/5.3inch and maximum magnification of 1:6 make it particularly
useful for close-up photography.
SLD (Special Low Dispersion) glass,
Super Multi-Layer Coating and the inner focusing system creates high
image quality. The HSM (Hyper Sonic Motor) ensures fast and quiet
autofocusing and allows full-time manual focus override.
The first circular fisheye lens exclusively for use with APS-C size digital SLR cameras
This lens is the first circular fisheye lens designed for APS-C size
digital SLR cameras. It produces circular image with a diameter of
12.3mm and angle of view of 180 degree in all directions, making it
ideal for capturing 360 degree panoramas.
Equisolid angle projection system
Due to the quantifiable angle/area relationship it produces, this lens
can be used for scientific applications such as solid angle
measurements of cloud distribution over the sky, or vegetation
distribution of the rain forest canopy.
The close focusing capability allows close-up photography
The minimum focusing distance of 13.5cm/5.3inch and maximum
magnification of 1:6 make it particularly useful for close-up
photography.
F2.8 Large aperture
It is an ideal lens for Astrophotography and Aurora photography. The
large depth of field enables photographers to emphasize the subject.
High level optical performance
SLD (Super Low Dispersion) glass provides effective compensation of
color aberration. Sigma’s Super Multi-Layer Coating minimizes flare
and ghosting. It is equipped with inner focusing system that creates
high definition and excellent image quality over the whole frame.
HSM (Hyper Sonic Motor)
The HSM ensures fast and quiet autofocusing and allows full-time manual focus override by rotation of the focus ring.
Convenience for photographers
This lens is equipped with a gelatin filter holder at the rear,
allowing the use of gelatin filters. The front cap adapter for
attachment of the 72mm front cap is included.
