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.

Ideally suited for architectural, landscape, and interior photography, this wide-angle prime lens offers an 18mm equivalent focal length.

The 15 elements in 12 groups optical design incorporates a pair of aspherical elements to reduce spherical aberrations and distortions for cleaner, more realistic rendering and sharper image quality.

Two extra-low dispersion elements and one Super ED element are also featured to control color fringing and chromatic aberrations for improved color fidelity and clarity.

A Nano GI coating has been applied to individual elements to suppress surface reflections, flare, and ghosting for improved contrast and color accuracy when working in strong lighting conditions.

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.

Physical aperture ring allows for intuitive adjustment over exposure settings, and incorporates a C (Command) position to permit camera-based aperture setting.

Dust- and weather-sealed physical construction enables working in harsh climates and temperatures as low as 14°F.

Rounded nine-blade diaphragm contributes to a pleasing bokeh quality.

Related Questions and Answers

Q: 1. Is it normal for there to be a clunking sound inside the barrel when lens is inverted and then returned? Thx

A: Yes it is normal.

Q: 2. Why does the listing specify this as 87mm (35mm Equivalent) when it's a 110mm lens? Typo?

A: All lenses are rate in terms of a full frame lens. So the FUJIFILM GF 110mm f/2 R LM WR Lens with UV Filter Kit is made for a medium format camera. So that lens on that camera is more like a 87mm lens. If you could put that on a full frame lens it would be 110mm.

Q: 3. What are the specifications / size of UV FILTER for 110mm gf Lens - this information is required for ordering the lens

A: The filter size 77MM, which is in fact in the specs listed by B&H.

Q: 4. Apparently, it is normal for the focus ring on this lens to travel forever in either direction without stops. Got this from Fujifilm directly, so sorry for the ignorance on my part. I've been a film shooter forever and this is the first digital camera I've ever bought. ?

A: This is typical of newer lenses, as a lot of lenses in the digital era operate electronically (typically referred to now as focus-by-wire), where the focus ring moves the elements via a motor and only when the lens is powered. This is opposed to the more mechanical/traditional SLR lens, where turning the focus ring physically shifts elements in the lens to focus.

Q: 5. Does this have manual focus like the first 23mm or is it auto only like the 90mm?

A: This lens doesn't have a manual focus clutch like the 23mm 1.4 mark I. It is focused electronically.

Q: 6. How to calculate MF DOF for crop and FF MF?

A: I suggest forgetting the word crop and crop factor. Please just go by what size your imager is, film or digital. On line you can find DOF calculators. Here is a good one. https://bit.ly/2AhsdN9Enter the sensor size, the lens mm, the aperture and the focus distance and you will have your Depth of Field. As a motion picture camera assistant, I calculated DOF dozens of times a production day. If I can do it, so can you.

Q: 7. Can someone recommend a neoprene case that would fit this attached to an X-T3?

A: There are a few neoprene cases that will fit the X-t3 with the XF 23mm lens attached. This is some option, https://bhpho.to/41w66uF .

Q: 8. Does this lens come with a hood? If not did you buy one?

A: Yes the FUJIFILM GF 32-64mm f/4 R LM WR Lens comes with a hood. When shopping our site you can always see what is included with an item by viewing the overview tab and finding the “In the Box” listing located on the right hand side of our web page.

Q: 9. I am considering a 120 macro for floral and close-up photography. I'm wondering if the 110 plus the 45 G WR extension tube would give me good floral/macro PLUS portraiture. I admittedly don't do many portraits, but would this idea give me a good two-for-one over just the 120 macro? I don't recall seeing photos of the 110 with macro-tube extension.

A: While you would not need an extension tube for portraiture photography, you may use the Fujifilm GF 110mm f/2 R LM WR Lens for portraiture, and you may add the use of the FUJIFILM MCEX-45G WR Macro Extension Tube so you may use the Fujifilm GF 110mm f/2 R LM WR Lens for close-up macro photography usage needs. The focal length would be slightly shorter than using the 120mm lens, but it would still be a good combination if you prefer the wider 110mm focal length for your portraiture usage needs. I think you'll be happy with the combination.

Q: 10. I am mainly a flowers, landscape, sunset kind of guy. I will jump into the Fuji medium format very soon. What 2 or 3 lenses would be best for my prefered subjects?

A: The FUJIFILM GF 23mm f/4 R LM WR Lens, B&H # FU234RWR, would be a good lens option for landscape images and sunset images of landscapes. To photograph close-up images of flowers, a macro lens such as the FUJIFILM GF 120mm f/4 Macro R LM OIS WR Lens, B&H # FU1204LMWR, would be a good option. For regular images of flowers (not necessarily close-up images), the FUJIFILM GF 63mm f/2.8 R WR Lens, B&H # FU6328RWR, would be a good option for your usage needs.
