Pros & Cons
Pros
Minimal distortion (Zero-D): Almost no distortion of straight lines, which saves a lot of time in architectural editing. Extreme Angle of View: This is one of the widest lenses available for the GFX system (13.5mm equivalent). Use of circular filters: Unlike other ultra wide angles, it allows you to use common 86 mm filters directly. Premium construction: Very robust and durable metal body. Defined stars of light: Thanks to its 5 blades, it generates "sunstars" with 10 very clean points. Close focus: Allows you to get up to 20 cm to highlight subjects in the foreground.
Cons
Manual focus: It does not have an autofocus (AF) motor. No communication with the camera: As it does not have electronic contacts, it does not save EXIF data (aperture or lens model) in the photo. Weight and size: It is a heavy lens (over 800g), which can unbalance smaller GFX bodies. Vignetting: Darkening is noticeable in the corners when shooting at maximum apertures, which is common at these angles. f/4 aperture: Although it is standard for this type of lens, it is not especially "fast" for night photography without a tripod.
