FUJIFILM GF 250mm f/4 R LM OIS WR Lens

A medium telephoto prime characterized by its sophisticated optical design, the GF 250mm f/4 R LM OIS WR from FUJIFILM is a 197.5mm-equivalent lens for the G-mount GFX camera system. Offering a mixture of long reach and a relatively bright f/4 maximum aperture, this lens is well-suited to isolating subject matter and working with shallow depth of field techniques. Complementing the visual compression of the telephoto focal length is an advanced optical layout, which uses one Super ED element and two extra-low dispersion elements to control color fringing and chromatic aberrations for a high degree of clarity and color accuracy. In addition to its optical assets, this lens is also distinguished by its five stop-effective image stabilization system that Minimizes the appearance of camera shake for sharper handheld imagery. It also features a linear autofocus motor that is both quick and quiet, and an internal focusing mechanism limits the overall lens length during use as well as maintains consistent image quality throughout the focusing range. The lens's magnesium-alloy build is also dust-, freeze-, and weather-resistant. Medium telephoto prime lens offers a 197.5mm equivalent focal length to realize a narrow field of view to suit wildlife and portraiture applications. Relatively bright f/4 maximum aperture enables a high degree of control over depth of field. The optical design incorporates one Super ED element and two extra-low dispersion elements to reduce chromatic aberrations and color fringing throughout the aperture and focusing ranges for notable clarity and color fidelity. A linear AF motor is used for quick, quiet focusing performance and an internal focusing mechanism maintains the overall length of the lens during operation and also produces consistent optical performance throughout the focusing range. Additionally, an updated mechanism also fixes the linear motor position when turning the camera off so the focus position remains the same.
