The optical construction of the Samyang 8 mm T3.8 Fish-eye CSII DH VDSLR (Video DSLR) DH lens is based on the 8 mm 1:3.5 Fish-eye CS model, and is specially developed for filming and video with APS-C sensor digital SLR cameras and professional camcorders with corresponding mounts.

This CSII version features a removable lens hood (DH), but is otherwise identical (optically and mechanically) to the standard version with a fixed, non-removable lens hood.

The Samyang 8 mm T3.8 fisheye lens has an aperture of f3.5 (indicated as T3.8, which is the f-number of a lens corrected for light loss during transmission through the lens. T values are important in the film industry, where TTL metering is not common, and also help to distinguish this video version of the lens from the standard Samyang 8 mm F3.5 fisheye. Optically, they are identical, with 10 elements in 7 optical groups, one aspherical lens element and multi-layer optics.

The features of this new model include geared rings compatible with professional focus tracking systems used in the film industry, as well as a de-clicked aperture ring with smooth adjustment. These modifications allow extremely precise control of focus and aperture during video recording | filming. This enables ultimate manual control of exposure when shooting scene by scene with different light source intensities, such as changing exposure values (EV) from indoors to outdoors, or even in-camera fades, etc.

It can also be perfectly used in photography, however users may find the standard version with a clicked aperture (Samyang 8 mm F3.5 fisheye) perhaps more suitable to avoid accidental aperture changes between shots.

The Samyang 8 mm T3.8 fisheye lens is a manual focus lens and offers a very large depth of field. The 8 mm T3.8 fisheye features a removable | detachable lens hood for shooting on full-frame cameras in order to produce the widest possible image circle.

On full-frame cameras with the lens hood removed, it produces a vignetted, almost circular image. This effect is required for users wishing to obtain the widest possible image | field of view for panoramic software on full-frame cameras, and this is one of the specific reasons why Samyang produced this version with a removable lens hood. The Samyang 8 mm fisheye lens is ideal for creating 360° panoramas and virtual tours, including full 360-degree images with appropriate equipment and various third-party panoramic software provided by other suppliers.

Available in 10 mounts: Canon, Canon-M, Nikon, Pentax K, Sony A, Sony E, Four-Thirds, MFT, Samsung NX and Fujifilm X.

The Samyang 8 mm fisheye lens offers some of the best optics in its class, with an excellent price-to-performance ratio. A specialised and affordable lens for every videographer or photographer, particularly suited to panoramic and video applications.
