2ndfocus, operated by E&I Creation, released the SG AF55mm F1.8 X lens from SG-image.
SG-image SG AF55mm Lens Features
The SG-image AF 55mm F1.8 STM is a large-aperture standard lens compatible with the Fujifilm X-mount, and combines excellent autofocus performance with cost performance. It uses an STM stepping motor to achieve quiet and smooth autofocus. This makes it easier to capture decisive moments, and it also supports smooth video recording and eye AF.
*Video AF and Eye AF are only available on cameras equipped with high-performance focal plane phase detection AF.
High image quality and ease of use
The lens is made up of 10 elements in 8 groups, including 5 high-refractive lenses, and provides good image quality with reduced chromatic aberration. The lens barrel and hood are made of high-quality metal, and the focus ring is comfortable to operate. It has a large aperture of F1.8 and 9 aperture blades. It can take photos with beautiful bokeh while suppressing image quality degradation in low-light environments.
Pursuing convenience
It is equipped with electronic contacts, so lens usage conditions are reflected in the Exif information of the shooting data. In addition, the mount is equipped with a USB terminal, so you can connect it to a PC and upgrade the firmware.
