The GF 30mm f/3.5 lens offers a 35mm equivalent focal length of 24mm, which results in a field of view of 84.7 degrees. The lens includes 13 elements across 10 groups, including a pair of aspherical lens elements and two ED elements. The aperture ranges from f/3.5 at the widest open to f/32 at its minimum, and the diaphragm includes nine rounded blades. Capable of focusing as closely as about a foot (0.32 meters), the GF 30mm delivers a maximum magnification of 0.15x. Further, for video users, the lens has focus breathing of just 0.05%, meaning the image should be very stable when focusing at different distances.
Image quality
The lens consists of thirteen lens elements in ten groups, including two aspherical elements and two extra-low dispersion (ED) elements. The high-performance lens groups are positioned to control various aberrations, especially distortion to which wide-angle lenses are prone, to achieve edge-to-edge sharpness. The lens is able to resolve an impressive amount of detail, compatible with 100MP sensors.
Portability
This compact lens weighs approximately 18 ounces (510g) and measures 3.9 inches (99.4mm) with a maximum diameter of 3.3 inches (84mm). In addition, the slim design balances well on a GFX System camera, making it a perfect lens to carry on-the-go.
Performance
The new GF30mmF3.5 R WR lens uses an internal focusing system, offering fast and quiet autofocus (AF). Focus breathing is just 0.05%, making it a great lens for recording video. Like all of Fujifilm's lenses in the GF family, the GF30mmF3.5 R WR incorporates Fujifilm's optical design and production technology processes to achieve a sub-micron level precision lens surface. This allows the lens to bring out the full potential of the FUJIFILM GFX 50S and GFX 50R mirrorless digital cameras, as well as the 100MP image sensor of the FUJIFILM GFX 100.
Durability
The lens is sealed at nine locations to make it dust and weather-resistant. It can also be used in temperatures as low as 14°F (-10°C), offering photographers peace-of-mind when shooting in inclement weather or dusty environments.
