GF 250mm f/4 R LM OIS WR Lens with UV Filter Kit Overview
Complementing the lens itself, the FUJIFILM GF 250mm f/4 R LM OIS WR Lens with UV Filter Kit from B&H bundles the telephoto prime with an 82mm UV filter.
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.
Focus Preset function button allows you to recall saved focusing positions for quick switching between focusing distances.
Optical Image Stabilization system compensates for up to five stops of camera shake to help realize sharper imagery when shooting handheld.
Physical aperture ring allows for intuitive adjustment over exposure settings, and incorporates a C (Command) position to permit camera-based aperture setting.
The front element features a hydrophobic fluorine coating to repel moisture.
Dust- and weather-sealed magnesium-alloy construction enables working in harsh climates and temperatures as low as 14°F.
Compatible with optional GF 1.4X TC WR Teleconverter, which extends the focal length to 350mm for even greater reach.
Hoya 82mm NXT Plus UV Filter
The Hoya 82mm NXT Plus UV Filter is a general use, clear filter designed to absorb ultraviolet light and reduce the bluish cast of daylight. Aside from the reduction of unwanted blue casts, no additional coloration or contrast is created, and adjustments to exposure are not required while using this filter. To prevent internal ghosting and reflections, each glass surface includes five layers of anti-reflection coating. These coatings also offer greater protection to the filter substrate and helps it to stay clean for longer than with uncoated filters. An additional hydrophobic coating results in an improved beading effect when in contact with water for greater cleaning efficiency.
This NXT Plus UV filter is constructed from Schott B270 glass for increased clarity as well as color fidelity and features an aluminum-alloy filter ring for durability while remaining lightweight. It is also useful as a general protective filter to leave on lenses at all times. Such filters help to reduce dust and moisture from reaching your front lens element and provide additional protection in case of drops or situations where scratching could occur.
