Presenting a super wide field of view, the GF 23mm f/4 R LM WR from FUJIFILM is an ultra-wide 18mm-equivalent prime designed for the G-mount GFX camera system. Ideally suited for architecture and interior photography, the lens's design employs a pair of aspherical elements to control distortion and spherical aberrations for accurate rendering, and a series of low dispersion elements are also featured for improved color accuracy and clarity. Additionally, a Nano GI coating has been applied to suppress lens flare and ghosting for improved contrast and color. Balancing the optical attributes, the lens also utilizes a linear AF motor with an internal focusing design for quick and quiet focusing performance, and a manual aperture ring also avails intuitive exposure adjustment and a Command position permits making camera-based aperture selections. Additionally, the lens is also dust-, freeze-, and weather-resistant for use in trying environmental conditions.

FUJIFILM 23mm f/4 R LM WR Lens Reviews
Excellent for Landscape
By Marlon
Rated 5 out of 5

I've only had this lens for a week, but after taking it to the park for some landscape shots, I was genuinely blown away. The images are incredibly sharp with virtually no distortion, and color fringing is impressively minimal. The level of detail it captures is nothing short of stunning—every texture and nuance comes through beautifully. I've attached a couple of photos I took with this lens, lightly edited in Lightroom to highlight its rendering capabilities.
Great lens!

It is a great lens and very sharp even when wide open. Distortion and light fall-off are well controlled. With LM motor focusing is fast and silent. For a F4 lens it is really bulky, especially when compared with GF 20-35/4 lens. I wish it could be a GF23/3.5 or even 2.8 at the same size and price.

Does this vignette when using an 82-77 step down ring and the Formatt Hitech Firecrest 85mm square filters (with the new style holder)?
Yes, the step-down ring 82-77mm will create vignetting on the FUJIFILM GF 23mm f/4 R LM WR Lens which is equivalent to the angle of view of an 18mm lens (35mm). The vignette will increment if a square filter holder system is attached in front of the lens.

Is there a FAST (wider aperture) version of his lens, like f/1.2 or f/2.8?
I'm sorry, no. There is not a faster version in this focal length.
