FUJINON GF45-100mm F4 R LM OIS WR Lens

Compact zoom with a constant F4 aperture and 5.0-stop OIS

The standard zoom “FUJINON Lens GF45-100F4 R LM OIS WR” is designed for the GFX Large Format*1 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, GF32-64mmF4 R LM WR and 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, enabling them to be more versatile and creative.

Astonishing image resolving power and wide tonal reproduction

GF45-100mmF4 R LM OIS WR 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.

Compact and lightweight Large Format standard zoom

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.

Fast, quiet and highly-accurate AF

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


Powerful image stabilization

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.


Highly robust design that withstands various shooting conditions

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 -10 degrees Celsius / 14 degrees Fahrenheit.

Weather-sealed at locations shown in green, for additional protection against the weather.



*1 An images sensor that measures 55mm diagonally (43.8mm x 32.9mm), providing approx. 1.7 times the area of a 35mm full-frame sensor
