Fujifilm GF 23mm f4 R LM WR

GF lenses achieve outstanding ultra-high resolution and have been designed to work with higher resolution sensors in the future. Utilizing the vast knowledge cultivated through the development of the XF lenses, GF lenses are Fujifilm's finest class of lenses and were designed by amassing various sophisticated technologies of Fujifilm. They are designed to fully unlock the superb performance potential of the GFX 50S.

The FUJINON GF 23mm F4 R LM WR Lens has a focal length equivalent to 18mm in the 35mm format and is perfectly suited for landscape and architectural applications. Despite the super-wide angle of view, distortion is kept to a minimum, and with the high-resolution performance extending all the way to the edges, the resulting image is outstandingly sharp. 

Product features

Low distortion with high resolving power
With a 12 groups and 15 elements construction using two aspherical lenses, one super ED lens, and three ED lenses, this lens suppress distortion despite being a super wide-angle lens with a 99.9° angle of view. Thanks to the optimal arrangement of the Super ED lens and three ED lenses, chromatic aberration of magnification is thoroughly suppressed, achieving high resolution performance all the way to the edge.

Nano GI coating
Nano GI coating has been applied to the lens which targets incident light entering the lens from diagonal angles due to the nature of the super wide-angle lens. Despite being a super wide-angle lens, the occurrence of ghosting and flare is effectively suppressed.

Fast and quiet AF
By adopting an inner focusing AF system to lighten the weight of the focus lens, and using a linear motor to drive the lens elements, fast and quiet AF is achieved, allowing for comfortable shooting.

Dust and weather resistant, capable of operating in environments as cold as -10°C
The lens has been sealed in nine areas, allowing the user to shoot with confidence and stability, even in dusty environments or in light rain.

High operability
The aperture ring has a C position (command dial mode) to allow lens aperture value to be changed via the command dial on the camera body. A locking mechanism has been added to the A (Auto) and C positions to prevent unintended movements of the aperture dial.

A protective filter PRF-82and front lens cap FLCP-82 will also be released.

Cumbria GB Professional
This is an excellent lens, sharp, low distortion and everything you'd expect from a pro-spec lens.
Price: a bit too expensive.

Angle of view: I'd prefer a wider lens but at present it is the widest available. An 18mm (15mm equivalent FF) would be ideal.
