Ultra-wide fisheye for Sony E-mount APS-C
The Rokinon Series II 8mm f/2.8 is a manual-focus diagonal fisheye designed for Sony E-mount cameras with APS-C sensors. It covers a 180-degree field of view, equivalent to a 12mm perspective in 35mm format. The lens weighs .15 kg and focuses as close as .3 metres. It suits photographers who want immersive, curved perspectives on a compact mirrorless body.
Built-in petal hood and internal focusing
A fixed petal-type hood is moulded into the barrel, shading the bulbous front element without adding length. Internal focusing keeps the lens at its shortest extension while turning the focus ring. Six diaphragm blades shape the aperture between f/2.8 and f/22. The optical formula uses 10 elements in 8 groups, including one aspherical and two extra-low dispersion pieces.
8 mm focal length on APS-C
The 8 mm focal length is the single figure that determines whether this lens fits the intended creative need. On an APS-C sensor it produces a full-frame-filling circular image with extreme barrel distortion. Buyers who want a rectilinear wide-angle or a fisheye for full-frame sensors should look elsewhere.

Questions about this item
Will the six-blade diaphragm or manual aperture ring need servicing later?
The six-blade diaphragm and manual aperture ring are mechanical parts with no user-serviceable components; normal care keeps them functional.
What optical limit appears first during extended shooting at f/22?
Diffraction softening becomes noticeable at f/22 before any other optical limit on this 8 mm fisheye.
How warm does the barrel get and how much power does it draw during all-day use?
The all-metal barrel stays near ambient temperature and the lens draws no power because it has no electronics.
