Lens OverviewSamyang 8mm f/3.5 Fisheye

The Samyang 8mm f/3.5 Fisheye CS II DH is a prime fisheye lens designed specifically for APS-C sensor cameras, available in a wide range of mounts including Canon EF, Nikon F, Sony E, Micro Four Thirds, and Pentax K. As a manual focus-only lens, it puts full optical control in the photographer's hands, making it a deliberate choice for shooters who prefer precise, hands-on focusing over autofocus automation. The f/3.5 maximum aperture offers a reasonable amount of light-gathering capability for a fisheye design, and the 8mm focal length delivers the dramatic wide-angle perspective that fisheye lenses are known for.

Weighing in at 435g, the lens has a solid, substantive feel without being excessively heavy for field use. The APS-C format coverage means it is optimized for crop-sensor bodies, making it a natural fit for enthusiast and advanced amateur DSLR and mirrorless shooters. With no image stabilization and a fully manual focus system, this lens rewards photographers who take the time to learn its characteristics and work deliberately within its design.

The broad mount compatibility across five camera systems makes it an accessible fisheye option for a wide variety of DSLR users.
