Fujifilm GF 250mm f4.0 R LM OIS WR - 243534

Fujifilm GF 250mm f4.0 R LM OIS WR - 243534

The lens is composed of 16 lenses in 10 groups including one super ED lens and two ED lenses, reducing chromatic aberration and achieving excellent image quality. Especially, super ED lens is used to reduces the fluctuations in chromatic aberration depend on the shooting distance. It enables to shoot minimum 1.4m close focus, maximum 0.22 x magnification ratio, and tele-macro shots with large bokeh effects.

Strong Image Stabilization

The lens is equipped with a powerful five-stop image stabilization function (CIPA guidelines). This allows photographers to make maximum performance of the GFX’s high image resolution even when taking telephoto shots where image shake might be obvious.

Various Functions

The lens’ functionality includes a focus limiter to enable faster autofocus speed by restricting focus range, focus pre-set for memorize focus settings previously set into the lens, and 4 focus control buttons located at the lens front enable to operate focus lock or autofocus.

Silent and High-Speed Autofocus

The linear motor to drive the focus lenses achieves high-precision, silent, and fast autofocus operation. In addition, the lens also now includes a new mechanism for fixing the linear motor position when turning the power off or playback, allowing the focus lens to be fixed.

Robust Design Appropriate for Various Tough Shooting Environments

The lens barrel is made with a magnesium alloy, ensuring both robust structural integrity and a light weight. Sealing has been applied to the lens in 18 different locations for dust and weather resistance and the ability to operate at temperatures of down to -10°C. A fluorine coating is also applied to the front lens element to repel water and dirt under tough outdoor situations.

1.4x Teleconverter

Fujifilm is simultaneously launching the 1.4x teleconverter (GF1.4X TC WR) which allows for telephoto shooting at a focal length of 350mm (approximately 277mm in 35mm format equivalent) while maintaining superior image quality. The maximum aperture is reduced by one F stop. As both the lens and the teleconverter are high quality, there’s hardly any deterioration in MTF when the teleconverter is attached.

What our Experts Think    

• The Fujifilm GF 250mm f/4 R LM OIS WR (243534) is a professional telephoto prime for the GFX medium format system, built for wildlife, sports, and distant subject work where reach and clarity are critical.
• It delivers an effective ~198mm full-frame equivalent field of view, offering strong subject isolation and natural compression for outdoor and action-focused photography.
• Experts highlight its high-end optical construction (16 elements in 10 groups, including ED and Super ED glass), which ensures strong sharpness, high contrast, and excellent control of chromatic aberrations even at long distances.
• The lens features a constant f/4 aperture, balancing light-gathering ability with consistent exposure control and manageable size for field use.
• A major strength is its optical image stabilization (around 5 stops), which significantly improves handheld shooting stability at long focal lengths.
• Its linear motor autofocus system delivers fast, quiet, and reliable focusing performance, making it suitable for wildlife tracking and dynamic outdoor subjects.
• Built with robust weather sealing and durable construction, it is designed for professional use in challenging environments such as dust, rain, and cold conditions.
• At approximately 1.4 kg, it remains relatively portable for a medium format telephoto lens, especially considering its stabilization system and optical complexity.
• Overall, experts consider it a dedicated long-reach workhorse for the GFX system, offering a strong balance of reach, stabilization, and image quality for photographers working in demanding field conditions.

Q&A
