The Fujinon 23mm f1.4 is Fujifilm classic. With the 35mm field of view and the f1.4 aperture, this lens can produce some amazing images in almost any situation. It’s the bread and butter for many street photographers and is one of those lenses you’ll never leave behind.

Fujinon 23mm f1.4 Review – First Impressions
When first I unboxing the Fujinon XF23mm f1.4 lens, I was a little surprised by its size. It’s not as big as some full frame lenses but it’s pretty hefty for an APS-C lens. Of course this is the price you pay for a lens this fast that is this wide and I think most people will be willing to accept that compromise.
The way the lens has been designed is really nice. It’s pretty much a big barrel of metal with 11 elements of glass strung through it. On the outside is a simple fly by wire aperture ring and a focus ring with the clutch that slides / clicks in and out of manual focus. This clutch I still don’t love and it’s found in a bunch of Fujifilm lenses. This is something that feels a little outdated since Fujifilm cameras all have a focus switch on the camera. This redundancy creates a little bit of confusion because if the camera is set to autofocus and the lens is still clicked into manual, you won’t be getting autofocus. I’ve found this creates some confusion if you’re not use to it.
While the focus ring has some nice resistance to it, the aperture ring has that Fujifilm lens problem of just being too easy to turn and I find myself always accidentally changing the aperture from slight bumps.
Shooting 23mm / a proper 35mm
There are two sort of standard primes, the 35mm and the 50mm. With APS-C it would be 23mm and 35mm because of the crop. Deciding between the two is one of the hardest decisions a photographer can make and I’m not really sure which I would rather have if I were stranded on a desert island. 35mm is just so useful, but 50mm is probably better if shooting portraits is your thing.
I mostly prefer wider since my thing is travel and landscape with some street mixed in, so for me, this lens is almost always with me.
The Faster Aperture
The f1.4 sounds really awesome and it is. In low light you don’t have to compromise for a high ISO and the depth of field is butter smooth. Performance at f1.4 is also very nice with only a little sharpness falloff in the center. However, the edges do get pretty soft.
Although this lens sounds like it’s the no brainer go-to choice to get a 35mm lens, there are a few things to consider that might deter you. One is that there is a 23mm f2 lens that’s weather sealed, has better focusing speeds and is less expensive. While this review is not about that lens or which one is better, that is an option that solves a lot of build quality problems for a lens that is only one stop slower.
Overall this lens produces some really nice image quality. Very sharp all around, controlled vignetting, chromatic aberrations, and great contrast and color rendering. However it uses some old focusing tech so you won’t be able to take advantage of the raw focusing power of Fujifilm’s new cameras.
While there are some elements to the lens design I don’t love, which I’ve mentioned above, it’s still a really nice and extremely well designed lens.
The 7 rounded blade aperture creates a really buttery smooth bokeh at lower apertures and the 11 elements in 8 groups with 1 aspherical element and the HT-EBC lens coating means you’re going to have very little issues with aberrations, flaring or distortion.
This lens also does not have the newer microcomputer to take advantage of the X-Pro2 and X-T2 faster contrast AF.
I once had part of my Sony / Zeiss lens hood fall apart only to find that it was held together by a piece of double sided tape – and that was a $900 lens!
You won’t find any double side tape holding a Fujifilm lens together and especially not this lens.
The lens aperture ring feels a little loose and I’m not in love with the way the focus ring clicks in and out of manual and auto focus, these are features you eventually adjust to and really, they’re not that big of a deal because they don’t affect your ability to take great shots. Unless of course you think you’re in autofocus and don’t realize your lens is still in manual and start shooting away only to realize later that none of your shots are in focus.
Autofocus is also a little noisy and there is some aperture chatter, so this lens would not be great for video.
Sharpness is good with this lens. It’s not amazing if you were to compare it to every lens ever made. For example that cheap 7Artisans 25mm f1.8 lens is much sharper, but the 23mm f1.4 is sharper than the Fujinon 27mm f2.8 and it does have better performance in the corners.
This is my second 23mm f1.4 lens. From looking at the forums and from my own personal experience, this lens is prone to misaligned elements. A small drop could do it or even a lot of vibrations. From my experience f1.4 to f2 was pretty unusable but f2 and higher the lens performed as expected. I sent the lens to Fujifilm and they gave me a new lens in ‘like condition.’ This referb is good but the left hemisphere is a bit softer than the right. So in these comparisons keep in mind that it is possible to get better performance out of your corners compared to what I have here. I have the worst luck with Fujifilm lenses and cameras.
I do add this lens to my Fujifilm fragile lens list and don’t recommend it for people who are rough on their gear. So like war photographers, or photographers with toddlers, same thing really.
Here are the sharpness charts across all apertures.
Sweet spot is between f4 and f8. This lens actually performs its best at f5.6 unlike the Fujinon 16mm f1.4, which is actually a bit softer at f5.6 compared to f4.
Color & Micro-Contrast
Contrast is really nice with this lens. It’s actually one of Fujifilm’s better high-contrast lenses. Here is a chart comparing contrast to a few other lenses. You can see it’s not as sharp as the 7Artisans 25mm, but there are some very nice inner tonal details and it’s all around better than the Fujinon 27mm f2.8.
These were shot at f5.6.
Distortion and Vignetting
Distortion and vignetting are very well controlled with this lens. Fujifilms RAW lens profiles help out a little bit here but not a lot is needed.
There is just a touch more vignetting at f1.4 in Lightroom with the Fujifilm profiles.
Distortion is very well controlled with only a subtle barrel distortion
Chromatic aberrations are very well controlled. There is some blue fringing in the corners with some purple fringing in the center at f1.4. Closing down the aperture completely cleans things up.
This is one of Fujifilms better Bokeh lenses. There are no soap bubbles or onion rings like that 16mm f1.4 and the shape is very circular with only some slight cats eyes towards the edges.
There is some blue fringing around the boarders of the bokeh when wide open.
Fujinon 23mm f1.4 Lens Review – The Bottom Line
It’s funny in almost all my reviews I end up saying that the lens I’m reviewing is one of my favorite Fujifilm lenses. It’s really hard to go wrong with any of Fujifilm’s lenses and Fujifilm 23mm f1.4 is simply incredible.
The optical design of the lens is fantastic so really the only thing that could be improved (given the laws of physics), is some build updates like a new microcomputer, weather sealing and a quieter focusing motor.
Should you get the 23mm f1.4 or the 23mm f2?
That I can’t speak on yet. I haven’t picked up the 23mm f2 lens but will soon. It looks very nice, however, so did the 35mm f2 lens, but I prefer the 35mm f1.4.
