Fisheye lens designed for APS-C digital SLR cameras
This lens produces a diagonal angle of view of 180°(167°for Canon). The diagonal field of view of this fisheye lens can be used to create amazing image expressions that cannot be seen with the human eye, such as exaggerated perspective and distortion. The lens produces a large depth of field making it suitable for a wide range of subjects.
High level of optical performance
The optical design, exclusive to fisheye lenses, provides correction of color aberrations and ensures superior peripheral brightness. The Integral hood blocks out extraneous light and the Super Multi-Layer Coating minimizes flare and ghosting, creating superior image quality.
The close focusing capability allows close-up photography
The minimum focusing distance of 13.5cm/5.3inch, and maximum magnification of 1:3.3 allows subjects to be as close as 1.8cm/0.7inch from the lens' front element. The close focusing capability together with a large depth of field allows close up photography that covers objects surrounding the photographic subject.
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.
Equisolid angle projection system
Due to the quantifiable angle/area relationship it produces, this lens can be used for scientific applications.
HSM (Hyper Sonic Motor)
The HSM models provide ultra quiet, high-speed autofocusing as well as full-time manual focus override.
Gelatin Filter Holder
This lens is equipped with a gelatin filter holder at the rear, allowing the use of gelatin filters.
