Best Fujifilm Fujinon XF 23 mm f / 1.4 R Black Friday and Cyber Monday Deals & Sales 2020:

The 23 mm is an equivalent in 24 x 36 mm to 35 mm. It is fitted with a diaphragm with 7 blades, which can be controlled automatically or manually using a ring. The construction is done on a formula with 11 lenses divided into 8 groups. There is an aspherical lens.

Like the 35mm, this Fujifilm Fujinon XF 23 mm f / 1.4 R looks good. With a 100% metal construction, it inspires confidence: robustness and manufacturing quality seem to be there. Compact, light, it will perfectly accompany a device of the size of an X-T1: count 300 g for a space requirement of 7 cm. Good point, it is very discreet and has a design with constant congestion.

Like all Fujifilm R lenses, it is equipped with a manual diaphragm ring, which is perfect for more intuitive use of the camera. It is notched at 1/3 of IL and offers an A position to switch to speed priority mode. Unfortunately, she lacks openness. Care should be taken not to inadvertently modify the opening due to improper handling. Good point, there is a small depth of field indicator in manual use of the focus.

The focus ring is quite pleasant to use. It has two positions. The first blocks it completely to leave the autofocus by hand – no manual retouching of the point is possible. The second, by pulling it towards the housing, reveals focus distance indicators for manual use. Unfortunately, it is too fluid, but has the advantage of having real stops.

In practice

The focal

A focal length corresponds to an angle of field – or angle of vision – covered by the camera equipped with the lens. The larger the focal length, the smaller the field of view: we speak of long focal length. Conversely, the shorter the focal length, the wider the field angle: we speak of wide-angle.

This 23mm is a 35mm equivalent. This lens is oriented wide-angle or standard focal length, for reportage or landscape photography for example.

The vignetting

All the lenses give an image whose periphery, and particularly the corners, are darker. The vignetting is measured in IL (Lumination Index): the value indicated measures the difference, in IL, between the amount of light received by the edges and that received in the center.

The vignetting on this Fujifilm Fujinon XF 23 mm f / 1.4 R is quite discreet and visible only at the largest openings. From f / 2.8, it becomes negligible.

The distortions

Objectives tend to “twist reality”. Geometric aberrations appear when one moves away from Gauss conditions. There are two types of geometric distortions: distortions in bearings and distortions in barrels.

With this 23mm, the distortions are clearly visible, but remain fairly low and very easily compensated with most post-production software.


The bokeh is to be related to the depth of field. We can compare it to the “quality” of the blur or to the way in which the objective goes from the net to the blur – a very subjective notion, even if certain elements make it possible to predict things – on images with shallow depth of field. It depends on many parameters including mainly the design of the lens, the shape and size of the diaphragm.

This 23 mm has a maximum aperture of f / 1.4: it is therefore able to produce images with very marked depth of field effects on a 35 mm equivalent. However, keep in mind that the depth of field also depends on the size of the sensor and the conversion coefficient used. A 23 mm depth of field is obtained, even if the images are 35 mm equivalents.


We tested 56 mm with a Fujifilm X-T1 and its 16 million pixel APS-C sensor (4.8 micrometers per side).

The notion of dive is quite delicate to deal with. This is what we can assimilate to the “feeling of sharpness” and / or to the “precision” that we observe on an image. It can be very different from one lens to another, from one focal to another and from one aperture to another. It can also vary between the center and the edges of the image. We usually say that the sharpness is optimal in the center and at the average openings: f / 8 or f / 11 for example.

In addition, the sharpness will depend on the definition of the sensor of your device (we tested the lens with an X-T1 of 16 Mpx) and the size of its sensor (APS-C for the X-T1). The smaller the pixels, the more the system will show its limits due to diffraction. This phenomenon increases as you close the lens diaphragm.

The X-T1 has a definition of 4896 x 3264 pixels. Each pixel therefore measures 4.8 micrometers side. The minimum aperture recommended to avoid diffraction problems is therefore f / 11!

In addition to the traditional photos of our test scene (you can download the RAW files in high definition), we spent the couple (objective + X-T1) in our home-made mill with the SFR + charter and Imatest.

The results of this Fujifilm Fujinon XF 23 mm f / 1.4 R are quite good without reaching the quality obtained with the 56 mm. The lens gives the best of itself between f / 5.6 and f / 11 with very sharp and especially homogeneous images between the center and the edges. At larger openings, it is a little more disappointing. The sharpness is much weaker in the center and drops significantly at the edges. From f / 11, diffraction makes its appearance.


  • Quality of construction, finish
  • Design and discretion
  • Manual diaphragm ring
  • Optical quality
  • Grand opening


  • Lack of consistency at larger openings
  • No optical stabilization
  • No manual stitch retouching
  • Slight vignetting at the largest openings


In the end, we recommend this Fujifilm Fujinon XF 23 mm f / 1.4 R equivalent to 35 mm without much hesitation. We appreciate the design and the quality of construction. The use of the diaphragm ring is a real pleasure and allows you to find beautiful sensations. The optical quality is also present, even if you have to be forgiving about the homogeneity of the sharpness on the edges with the largest openings. The absence of optical stabilization (of questionable interest) is overlooked by the large aperture of f / 1.4 which also allows you to obtain beautiful depth of field effects. point.
