The Fujifilm GF 45-100mm F4 first appeared on the company’s medium format lens roadmap in September 2018 for release in 2020 and it’s now slated to ship in February.
This new lens joins the current family of interchangeable GF Lenses, designed for the GFX large format Camera System and covers some of the most frequently used focal lengths by photographers. The GF45-100mmF4 R LM OIS WR lens has an equivalent focal length range of 36mm and 79mm on a smaller 35mm format system, a maximum aperture of F4 and is a natural fit with two other GF Zoom Lenses – the GF32-64mmF4 R LM WR and the GF100-200mmF5.6 R LM OIS WR. Together, these three lenses provide photographers with a broad range of focal lengths, accommodating a wide range of shooting styles and enabling them to become incredibly versatile and creative.

Combining rugged construction with high-performance optics, GF45-100mmF4 R LM OIS WR is an incredibly versatile lens that is perfect for capturing nature, landscapes, or portraits. Featuring powerful 5-axis image stabilization, one super ED lens element, and a near-silent, high-speed autofocus motor, this is the perfect tool for creating images in challenging and unpredictable situations. Its dust- and weather-resistant construction allows the lens to operate in temperatures down to 14 degrees Fahrenheit/-10 degrees Celsius and its high-resolution performance and wonderfully smooth bokeh will capture the atmosphere of any scene or subject.

The GF45-100mmF4 R LM OIS WR lens consists of 16 elements in 12 groups, including three aspherical elements, one Super ED element, and one ED element to effectively control spherical aberration, field curvature, and chromatic aberration. This minimizes the negative effects of various forms of aberration, such as luminance shift and color bleeding, to deliver astonishing image sharpness.

Weighing 2.2lb (1,005g), measuring 5.69in (144.5mm) long, and having a diameter of 3.66in (93mm), the lens is extremely portable and compact despite being a 2.2x zoom for a large-format camera system.

The use of an Internal Focusing system has minimized the size and weight of the focusing group, which is driven by a linear motor to achieve fast, quiet and highly accurate AF.

The lens is equipped with five-stop image stabilization (CIPA guidelines), allowing photographers to make the most of the high-resolution sensors found in GFX System cameras, especially when making images hand-held.

The lens has 11 seals for dust and weather resistance to allow for peace of mind in tough environments, allowing for operation at temperatures down to 14°F / -10°C.

The Fujifilm GF 45-100mm f/4 R LM OIS WR will begin shipping in “late February 2020” for $2,300.
