Fujifilm GF 250mm f4 R LM OIS WR Lens
The GF 250mm F4 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 the high resolving power necessary for supporting 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, a 1.4x teleconverter provides coverage for telephoto shooting up to approximately 277mm in 35mm format equivalent, without any image quality deterioration.
The lens is also equipped with the new focus pre-set function*, which allows the photographer to instantly activate focus settings previously saved in the lens memory. The use of a magnesium alloy lens barrel reduces the product’s weight, and the dust and weather resistant specifications, which also provide the ability to operate in temperatures down to -10°C, ensure that this new lens will serve as a trusted partner for professional photographers.
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. The super ED lens is used to reduce the fluctuations in chromatic aberration based on the shooting distance. It enables one to shoot a minimum of 4.5 ft close focus, a 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. This allows photographers to experience the maximum performance of the GFX’s high image resolution, even when taking telephoto shots where image shake might be obvious.
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 front of the lens front to enable and operate focus lock or autofocus.
*An upgrade to the GFX50S firmware is required to operate the focus pre-set function and focus control buttons. This functionality is included in the new version of the GFX50S firmware that will be released at the same time.
Silent and High-Speed Autofocus
The linear motor to drive the focus of the lenses performs with 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 lens. 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.
