The compact system makes it a perfect choice for snapshots and landscape photography.

GF lenses are Fujifilm’s highest-grade lenses that deliver superior image quality with high-resolution performance and wide tonal reproducibility. This is made possible by the use of Fujifilm’s exceptional optical design technology and production technology that processes lens surfaces with the precision of a submicron level, fostered through the development of FUJINON lenses. The industry-leading lens lineup includes cine lenses that have recently won the Engineering Emmy Awards***. These lenses can be mounted on the FUJIFILM GFX100 (“GFX100”), released in June this year, to bring out the full performance of GFX100’s 102 million pixels image sensor, achieving the world’s highest level of photographic image quality by utilizing the company’s unique color reproduction technology.

The GF50mmF3.5 R LM WR, to be released this time, consists of 9 lens elements in 6 groups, including one aspherical lens. It controls spherical aberration and distortion*4 thoroughly to achieve an astonishing image sharpness and wide tonal gradation. The compact design measuring just 48mm in length and weighing 335g is complimented with silent and high-speed autofocus (AF) to provide exceptional mobility. Furthermore, the lens is dust and weather resistant and can be used in temperatures as low as -10°C, facilitating photography in light rain or in dusty outdoor areas. These features make it highly reliable photographic equipment suitable for professional photographers.
