This Samyang 8mm F3.5 Fish-eyes CS II Lens provides a diagonal field of view of 180 degrees on a 1.5x crop APS-C DSLR sports f/3.5 maximum aperture and the AE version we are reviewing here is available for around 250 for Nikon cameras with an APS-C size sensor. The AE version has a metering chip built in to transfer exposure information between the lens and the camera. Focusing is manual and the action of the focus ring is smooth and precise. Focus distances are marked on focusing ring although there is no hyperfocal scale which is a shame. Taking images of anything over two to three metres away is simple as the lens can simply be left set on or close to infinity. For closer distances it is recommended to use the electronic focus confirmation feature of your DSLR or a dedicated focusing screen for manual focus lenses if taking still images using the viewfinder. If recording video viewing a magnified section of the frame will ensure accurate focusing. At maximum aperture sharpness is good in the centre of the frame and only slightly behind towards the edges of the frame. Stopping down improves sharpness in the centre of the frame dramatically reaching outstanding levels by f/5.6. However clarity towards the edges of the frame is never quite as good reaching very good levels between f/5.6 and f/11.
