SG-image 75mm F1.2 Product overview
This product is the SG-image brand’s first manual focus lens for medium format mirrorless cameras, compatible with Fujifilm G mount and Hasselblad X mount.
The 75mm focal length and wide f/1.2 aperture create a shallow depth of field that makes subjects stand out, while also producing smooth and striking bokeh. Enjoy the rich tonality and three-dimensional rendering unique to a medium format sensor in a wide range of shooting scenes, from portraits to still lifes and snapshots.
Furthermore, stopping down the aperture enhances the overall resolution of the image, and the ability to enjoy the changes in expression from wide open to wide open aperture is another appealing aspect of this lens. The lens barrel is made of metal, and attention has been paid to the feel of the focus and aperture rings, resulting in a solid build that supports the joy of taking pictures.


SG-image 75mm F1.2 Main features
SG-image’s first medium format mirrorless camera compatible camera.
Compatible with Fujifilm GFX series and Hasselblad X system. It takes advantage of the medium format sensor’s wide light-receiving surface to produce rich tonality, depth, and a sense of atmosphere in its images. The Fujifilm G-mount (GFX) version is limited to 200 units worldwide, and the Hasselblad X-mount version is limited to 100 units worldwide.

The large F1.2 aperture produces exquisite bokeh.
At its widest aperture of F1.2, it produces a large bokeh effect that softly illuminates the subject, offering high expressive power for portraits and close-ups. Stopping down the aperture allows for sharper, more detailed images, making it a versatile lens for a wide range of expressions.
Optical design employing high refractive index lenses
The lens features a 6-group, 7-element construction with four high-refractive-index lenses. While covering the medium format, it achieves both soft rendering at wide apertures and sharp reproduction when stopped down. The 12-blade circular aperture contributes to natural and beautiful bokeh.
High build quality that satisfies the desire to own.
The lens barrel is made of metal, achieving both robustness and a premium feel. It has a presence befitting a medium format camera and a solid, reliable texture that makes it easy to use.
Focus ring and aperture ring designed for ultimate operability
