The use of two glass-molded aspherical lenses allows for a smaller size while maintaining high resolution. Additionally, instead of using a focal-plane shutter, a leaf shutter\u2014 a first for the GFX series \u2014 has been integrated, further enhancing the compact design.&nbsp;<\/p>\n\n\n\n<p>The forward-tapering silhouette of the lens was achieved by repositioning the focus-moving components toward the front, beautifully complementing the rangefinder style. This design creates an unobtrusive form that fits snugly in your hand when shooting.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"682\" src=\"https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/1-2.jpg?width=1024&#038;height=682\" alt=\"\" class=\"wp-image-263769\" srcset=\"https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/1-2.jpg?width=1024&amp;height=682 1024w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/1-2.jpg?width=300&amp;height=200 300w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/1-2.jpg?width=768&amp;height=512 768w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/1-2.jpg?width=400&amp;height=267 400w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/1-2.jpg?width=365&amp;height=243 365w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/1-2.jpg?width=600&amp;height=400 600w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/1-2.jpg?width=717&amp;height=478 717w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" data-recalc-dims=\"1\" \/><\/figure>\n\n\n\n<p>There is no merit in large format photography if it compromises resolution for the sake of compactness. When we say that \u201ccompactness and high image quality coexist thanks to the advantages of a fixed lens,\u201d many will recall the lens updated with the X100V. That design philosophy has been applied to this lens as well.&nbsp;<\/p>\n\n\n\n<p>The 35mm (28mm equivalent in 35mm format) that captures everything in sight. To fully utilize this wide image, it is essential for the image to maintain sharpness even at the periphery. It is impossible to predict which part of the 100 million pixels will be most important. Generally speaking, the larger the canvas, the easier it is to conceal details. However, the GF lens is engineered to leverage the large format sensor of the GFX to resolve even the finest details with the same density as the X series. Even when enlarged, the details remain intact, allowing the lens to convey the subject&#8217;s texture and the atmosphere of the scene effectively. The development philosophy of GF lenses has remained steadfast, even with the single-unit design.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/2.jpeg?width=1024&#038;height=576\" alt=\"\" class=\"wp-image-263770\" srcset=\"https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/2.jpeg?width=1024&amp;height=576 1024w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/2.jpeg?width=300&amp;height=169 300w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/2.jpeg?width=768&amp;height=432 768w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/2.jpeg?width=400&amp;height=225 400w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/2.jpeg?width=365&amp;height=205 365w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/2.jpeg?width=600&amp;height=338 600w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/2.jpeg?width=417&amp;height=235 417w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/2.jpeg?width=717&amp;height=403 717w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" data-recalc-dims=\"1\" \/><\/figure>\n\n\n\n<p>Photo by Reuben Wu&nbsp;<\/p>\n\n\n\n<p>With a fixed lens, there are no mount restrictions, greatly enhancing the freedom of optical design. We pursued superior image quality with high precision, utilizing two aspherical lenses to suppress spherical aberration and field curvature. Additionally, we developed a new Nano GI coating optimized for lenses with larger curvatures due to their compact size, significantly reducing reflectance in peripheral areas and minimizing ghosting. This results in consistent image quality not only at the center but also throughout the periphery.&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/3-1.jpeg?width=1024&#038;height=576\" alt=\"\" class=\"wp-image-263771\" srcset=\"https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/3-1.jpeg?width=1024&amp;height=576 1024w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/3-1.jpeg?width=300&amp;height=169 300w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/3-1.jpeg?width=768&amp;height=432 768w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/3-1.jpeg?width=400&amp;height=225 400w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/3-1.jpeg?width=365&amp;height=205 365w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/3-1.jpeg?width=600&amp;height=338 600w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/3-1.jpeg?width=417&amp;height=235 417w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/3-1.jpeg?width=717&amp;height=403 717w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" data-recalc-dims=\"1\" \/><\/figure>\n\n\n\n<p>Photo by Kirsten Luce&nbsp;<\/p>\n\n\n\n<p>The lightness, a characteristic of rangefinder-style cameras, is achieved not only through compactness but also through advanced autofocus (AF) technology. <\/p>\n\n\n\n<p>However, the incidence angle is tighter in fixed-lens models compared to conventional GFX series models due to their smaller size, resulting in less light required for phase detection AF. The latest algorithm, praised in the GFX100S II, has been fine-tuned to optimize performance for the fixed-lens GFX100RF. Furthermore, the DC motor ensures high speed and torque. The fixed-lens design and precise adjustment maintain seamless communication with the lens mount, allowing for smooth movement of the focus ring during manual focus (MF).&nbsp;<\/p>\n\n\n\n<figure class=\"wp-block-image size-large\"><img loading=\"lazy\" decoding=\"async\" width=\"1024\" height=\"576\" src=\"https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/5.jpeg?width=1024&#038;height=576\" alt=\"\" class=\"wp-image-263773\" srcset=\"https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/5.jpeg?width=1024&amp;height=576 1024w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/5.jpeg?width=300&amp;height=169 300w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/5.jpeg?width=768&amp;height=432 768w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/5.jpeg?width=400&amp;height=225 400w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/5.jpeg?width=365&amp;height=205 365w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/5.jpeg?width=600&amp;height=338 600w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/5.jpeg?width=417&amp;height=235 417w, https:\/\/fujifilm-x.b-cdn.net\/wp-content\/uploads\/2025\/03\/5.jpeg?width=717&amp;height=403 717w\" sizes=\"auto, (max-width: 1000px) 100vw, 1000px\" data-recalc-dims=\"1\" \/><\/figure>\n\n\n\n<p>Photo by Giulio Di Sturco&nbsp;<\/p>\n\n\n\n<p>Optimization through motor control, grease adjustments, and enhanced component rigidity physically reduces vibration.
