At its core, the GF45-100mmF4 features a sophisticated optical construction of 16 elements in 12 groups, including three aspherical elements, one Super ED element, and one ED element. This advanced design effectively mitigates spherical aberration, field curvature, and chromatic aberration, ensuring astonishing image sharpness and uncompromised clarity across the entire zoom range and throughout the frame—a necessity for the high-resolution GFX sensors.
Despite its robust optical capabilities and 2.2x zoom ratio for a large format system, the Fujifilm GF45-100mmF4 maintains remarkable portability. Weighing a mere 2.2lb (1,005g) and measuring a compact 5.69in (144.5mm) in length, it’s designed for comfortable handheld use and easy transport. The internal focusing system, driven by a powerful linear motor, delivers fast, quiet, and highly accurate autofocus performance, crucial for capturing fleeting moments with precision. Further enhancing its utility, the lens incorporates a 5-stop optical image stabilization (OIS) system, empowering photographers to achieve tack-sharp images even in challenging low-light conditions or when shooting handheld, fully leveraging the GFX system's resolution potential.
Built to withstand the rigors of professional use, the GF45-100mmF4 boasts a durable construction with 11 weather-sealed points. This provides robust dust and weather resistance, ensuring reliable operation in harsh environments and extreme temperatures down to 14°F (-10°C). For professional GFX users seeking a versatile, optically brilliant, and resilient standard zoom, the Fujifilm GF45-100mmF4 is an essential addition, offering unparalleled performance and peace of mind in any photographic endeavor.
