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.
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 minimises the negative effects of various forms of aberration, such as luminance shift and colour 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 lens uses the internal focus AF system that drives smaller and lighter focusing elements. It uses a stepping motor, known for its quiet operation and accuracy, to achieve fast and silent autofocus.
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.
*1 An image sensor that measures 55mm diagonally (43.8mm x 32.9mm), providing approx. 1.7 times the area of a 35mm full-frame sensor
