Telephoto Prime Lens for G-Mount GFX Cameras
The GF 250mm f/4 R LM OIS WR is a telephoto lens that achieves approximately 198mm in 35mm format equivalent, bringing together Fujifilm’s proprietary optical design technology: it offers high resolving power for supporting the further enhancement of image resolution in the future.
The lens is capable of capturing the atmosphere of any scene through a combination of high-resolution performance and rich bokeh effect. Attaching the GF 1.4X TC WR teleconverter provides coverage for telephoto shooting up to approximately 277mm in 35mm format equivalent, without any image quality deterioration.
Ultra-High Image Quality
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 Stabilisation
The lens is equipped with a powerful five-stop image stabilisation function (CIPA guidelines). This allows photographers to make the 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 memorising 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 lightweight. 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
The 1.4x teleconverter (GF1.4X TC WR) 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.
