Fuji 16mm f/1.4 R WR XF

Fujifilm Fujinon XF 16mm f/1.4 R WR ASPH for X-mount cameras (metal 67mm filter thread, 13.2 oz./375g, 0.49'/0.15m close focus, about $849). enlarge. I got mine at this link to it at Adorama; these links to it at Amazon and at B&H are also great places to get it.

This ad-free website's biggest source of support is when you use those or any of these links to approved sources when you get anything, regardless of the country in which you live. Fuji does not seal its boxes, so never buy at retail or any source not on my personally approved list since you'll have no way of knowing if you're missing accessories, getting a defective or damaged customer return or a used product. Buy only from the approved sources I use myself for the best prices, service, return policies and selection. Thanks for your support! Ken.

This is an ultra-fast wide lens for use in low light. It has no visible distortion, it's super-sharp, has no lateral color fringes and has no visible light falloff even at f/1.4 as shot on the Fuji X-mount cameras. It's all-metal, too!

Like all Fujinon XF lenses, there is no mechanical manual focus. It's all electronic.

Again like all Fujinon lenses, there is no instant manual focus override; you have to move the focus ring forward or back to switch between auto and manual.

In many Fujifilm cameras if you update the firmware, there is an AF+MF option deep in the menus (look in the fifth Camera menu in the X-E2 for instance) that will give instant manual override only if you turn this menu item ON and then only as long as your finger is halfway down on the shutter.

Fuji has for many decades, just like Canon and Nikon, also made far more advanced optics, like binoculars for the military and for use in space, as well as lenses for motion pictures and television with six-figure price tags at discount. Unlike mud brands like Sigma and Tamron (or even LEICA), Fujinon has loads of experience actually supplying optics that cost more than some people's houses, and puts that same know-how into these lenses.

Fuji calls this the Fujinon Aspherical Lens Nano GI XF 16mm f/1.4 R WR, or XF16mmF1.4 R WR.

Fujinon is Fujifilm's brand name for their lenses.

Aspherical means specially shaped lens elements for better sharpness.

Nano GI means that one surface has Fuji's new sub-wavelength nano variable-index-of-refraction anti-reflection coating. It's the same as Nikon's Nano and Canon's SWC.

XF is Fuji's line of good lenses for their X-mount cameras.

R means it has an aperture ring.

WR means weather resistant.

When used on the X-mount cameras with their 1.52x sensors, it sees the same angle of view as a 24mm lens sees when used on a 35mm camera.

When used on the X-mount cameras in their 1:1 square crop mode, it sees the same angle of view as a 58mm lens sees when used on a 6x6cm (2¼"square) medium-format camera. This is about the same as a 31mm lens sees when used on a 35mm camera.

Overall      performance      top

The Fuji XF 16mm f/1.4 R WR is optically quite good, excelling at falloff and distortion, as well as mechanical quality.


Auto and Manual Focus      performance      top

Autofocus is moderately fast, and it's very accurate, especially at f/1.4.

Fuji's focus system is closed-loop, read directly from the image sensor, so it automatically compensates for any mechanical errors.

Open-loop systems of DSLRs and LEICAs can't compensate for these errors and sometimes have focus errors (offsets) which we don't have in the Fuji system. Bravo!

On the other hand, it's not as fast as Fuji would like you to believe. Unlike a DSLR, AF isn't instant; it usually takes a moment to lock-on.


Bokeh      performance      top

It's rare to get anything significantly out of focus on any 16mm lens; background blur has more to do with focal length than aperture.

The only way to make the background soft is to get very close to the subject.

Once you get close enough to get anything out of focus, bokeh is pretty typical: soft, but blur circles are still circles, not just undefined blobs.

Coma       performance     top

Coma is weird smeared blobs that appear around bright points of light in the corners. They happen with fast and wide lenses at large apertures. Coma goes away as stopped down, and tends not to be seen in slower and tele lenses.

Coma also can make the far corners look like they have a radial blur even if you don't have points of light to excite it.

This aspherical lens is far better than any spherical lens, like LEICA's 35mm f/1.4, or Nikon's 24mm f/2, each of which is awful compared to this 16mm f/1.4.

Coma is visible at f/1.4 and f/2. It's gone by f/2.8.


Distortion      performance      top

Distortion, as shot on the X-T10 which is probably correcting it automatically, is completely invisible, whoo hoo!

Maybe use a correction factor of +0.1 in Photoshop's Lens Correction filter, or just forget about it.


Ergonomics      performance      top

Fuji XF 16mm f/1.4 R WR

Fuji XF 16mm f/1.4 R WR for X-mount cameras.

Ergonomics are great! Grab and go.

It feels great; it's a real metal lens. The only other real metal lenses made today are almost exclusively from LEICA; Nikon and Canon have been churning out mostly plastic since the 1980s.

The dedicated aperture ring is also mandatory for real photography, but absent on most other brands of lenses.

A whine about the aperture ring is that it needs a deeper detent or an easily-released lock at A, otherwise it's easy to knock it to f/16 by accident.

It's silly to have all the third-stop clicks. We need the full stops more deeply detented so we can feel them with our eyes closed.


Falloff (darkened corners)      performance      top

Light falloff is completely invisible, even at f/1.4, as shot on the X-T10 which is probably correcting it automatically.

Even shooting white walls wide-open at f/1.4 to exaggerate it, it's still insignificant. I've greatly exaggerated it by shooting a white plate and showing it against a gray background:

Filters, Use with      performance      top

There's no problem with vignetting, even with a couple of stacked filters!

The filter ring doesn't move at all.

The all-metal filter ring is a pleasant surprise compared to the plastic rubbish from other brands. For instance, Nikon's $2,200 24mm f/1.4 has a crummy plastic filter thread.


Flare and Ghosts     performance      top


Flare, 28 August 2015. (X-T10, ISO 400, 200% Dynamic Range, XF 16mm f/1.4 R WR, f/6.4 at 1/420.)

Shooting directly into the sun or letting the sun shine on the front of the lens from outside the picture area and then deliberately putting something dark in the image can show some veiling flare. No big deal, don't do that or shield the lens with your hand.

While flare is a bit worse than average for a modern lens, it's never visible in actual shooting.

See also Sunstars for more samples.


Lateral Color Fringes      performance      top

There are no lateral color fringes as shot on the X-T10. It's probably correcting any that the lens may or may not have.


Macro      performance      top

It focuses to within inches of the front of the lens. Rated at 6"/0.15m from the image plane, that means about 2"/6cm from the front of the lens:

It's super sharp:

Sharpness      performance      top

Warning 1: Image sharpness depends more on you than your lens.

Warning 2: Lens sharpness doesn't mean much to good photographers.

With those caveats, the Fuji XF 16/1.4 is sharp at all settings, but softer in the far corners at f/1.4 and f/2 due to coma.

Palm, 28 August 2015 RP

Library, 28 August 2015. (Fuji X-T10, XF 16mm f/1.4 R WR at f/1.4 at 1/30 at ISO 200, Perfectly Clear V2.) Camera-original © file.


Here is its rated MTF at f/1.4, which confirms the coma:

MTF at 15 cycles
MTF at 45 cycles
MTF at 15 cyc/mm (10 cyc/mm equiv.)
MTF at 45 cyc/mm (30 cyc/mm equiv.)


Spherochromatism       performance     top

I see a little spherochromatism, also called color bokeh by hobbyists. This means that out-of-focus highlights may take on slight color fringes.

If you do see anything, background highlights may be fringed with green, and foreground highlights might be tinged with magenta.

This goes away as stopped down. I doubt you'll ever see it.


Sunstars      performance      top


Sunstars at f/8, 28 August 2015, as-shot. bigger.



Sunstars at f/16, 28 August 2015, as-shot. bigger.

The rounded 9-blade diaphragm makes no sunstars at large apertures, however it becomes straight as stopped down and can make great sunstars on brilliant points of light at f/16.

It will make some small sunstars at reasonable apertures, like f/8, so it's better than many modern lenses.


Recommendations       top

Intro   Specs   Performance   Recommendations   More

The Fuji XF 16mm f/1.4 R WR is a great lens for low-light, giving you the longest reach into the dark hand-held of any lens. While an f/1.2 lens is faster, all the f/1.2 lenses are longer, which means you can't hand-hold them at shutter speeds as slow as you can with this 16mm lens. This shorter lens also has more depth of field, so far more is in focus at f/1.4 with this lens than with any longer lens.

Personally I rarely shoot with this 24mm-equivalsnt focal length; I prefer the 23mm f/1.4 and 35mm f/1.4 lenses which see more as I do, and if I want wide, I use the 10-24mm f/4 OIS.

The only advantage to this lens is if you really shoot it at f/1.4. When stopped down it's the same as using any of Fuji's other zooms at their 16mm settings.

If you've found my research here helpful, my support to run this ad-free website comes from when you using any of these links to it at Adorama, at Amazon or at B&H when you get yours, or when you get anything at these links to approved sources. Please always use these links when getting any of your gear so I can continue to share what I know; it's what supports me. If you take the chance of buying elsewhere (or especially at retail), remember that Fuji doesn't seal its boxes. Unlike a bottle of milk or a CD which is sealed, buy your 16mm lens elsewhere or at retail and you'll not only cheat me out of the work I've done here to help you, you run the risk of getting a lens that's a customer return, dropped, missing accessories or been used for store demos. Never buy at retail.
