Fuji 90mm f/2 R LM WR XF

Fujifilm Fujinon XF 90mm f/2 R LM WR for X-mount cameras (metal 62mm filter thread, 18.9 oz./536g, 2'/0.6m close focus, about $949). 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 a fast telephoto for Fuji's X-mount cameras. It's optical perfection in an all-metal body. Bravo!

It's ultrasharp even at f/2 in the far corners, devoid of color fringes or distortion as shot on Fuji's X-mount cameras, and has ultrasmooth bokeh.

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

Most newer Fuji X cameras offer an AF+MF mode option in their AUTOFOCUS SETTING menu, in which case you have instant manual focus override so long as you're holding the shutter halfway. Otherwise you have to move an AF mode switch on your camera to swap between auto and manual focus.

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 even 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.

This Fujinon 90mm is exquisitely made out of metal, and has superlative optics that are super-sharp edge-to-edge even wide open at f/2.

This is a superb portrait or astronomy lens for Fuji cameras.

WR stands for weather resistant.

Fuji calls this the Fujinon Lens Super EBC XF 90mm f/2 R LM WR, or XF90mmF2 R LM WR.

Fujinon is Fujifilm's brand name for their lenses.

Super EBC is Fujinon's brand of multicoating, standing for Super Electron-Beam Coated.

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

R means it has an aperture ring.

LM means Lick Me, an odd twist lost in translation from Japanese relating to humidity resistance.

WR means weather resistant.

∅ 62 means it takes 62mm filters.

Focal length


When used on the X-mount cameras with their 1.52x sensors, it sees the same angle of view as a 135mm 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 325mm lens sees when used on a 6x6cm (2¼"square) medium-format camera. This is about the same as a 170mm lens sees when used on a 35mm camera.

Overall      performance      top

The Fuji XF 90mm f/2 R LM WR is optically perfect. As shot on Fuji's cameras which compensate for everything, it's as perfect as I can measure.

It's ultrasharp and has no falloff or distortion at any setting, and is also made extremely well.


Auto and Manual Focus      performance      top

Autofocus is surprisingly fast for a tele. Fuji is playing some sort of tricks internally; you can feel half the lens' guts wiggling around inside when it's not on the camera, and I assume that this means that the innards are driven by voice coils to move super-fast for focus.

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!


Bokeh      performance      top

Bokeh is magnificent, one of the hallmarks of this lens.

Notice also how the spiderweb is deadly sharp at f/2 in the one section front and center that's actually in focus.


Coma       performance     top

I see no coma, which is excellent.


Distortion      performance      top

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


Ergonomics      performance      top

Fuji XF 90mm f/2 R LM WR

Fuji XF 90mm f/2. bigger.

Ergonomics are great! Grab and go. Most of the lens is the metal focus ring.

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/2, as shot on the X-T10 which is probably correcting it automatically.

Even shooting white walls wide-open to exaggerate it, it's invisible. I've greatly exaggerated it by shooting a gray 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 does not move.

The all-metal filter ring is a pleasant surprise compared to the plastic rubbish from other brands.


Flare and Ghosts     performance      top


Flare, 03 September 2015. Fuji X-T10, Auto ISO 400, 200% Dynamic Range, XF 90mm f/2 R LM WR, f/8 at 1/750.

There's no flare or ghosting.

If you really go out of your way to excite it, there is a slight green ghost opposite the sun.

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.

This is superb performance.


Macro      performance      top

It gets very close:

It's super sharp:

Noises When Shaken

Something is flopping around in there. It sounds like the focus group wobbling around. I'd go easy on letting your kids shake this too much, but this is normal.


Made in



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 90/2 is essentially perfect: ultra sharp at all settings everywhere in the image. Bravo!

Here is its rated MTF at f/2:

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

Spherochromatism, erroneously called color bokeh by hobbyists, is common in fast long lenses.

As expected, the Fuji 90 has spherochromatism visible to the expert observer. This means out-of-focus highlights behind the subject may have green fringes, and out-of-focus highlights in front of the subject may have magenta fringes.

This is put to deliberate advantage in this lens, since it means that green backgrounds (think outdoor portraits) will be even more magically soft.

Of course there are no fringes at all when things are perfectly in focus, spherochromatism is what happens to things that are out of focus.


Sunstars      performance      top


Sunstars, 03 September 2015. X-T10, Auto ISO 400, 200% dynamic range, XF 90mm f/2 R LM WR, f/16 at 1/320.

The rounded 7-blade diaphragm doesn't make much in the way of sunstars.

The best you can hope for is soft sunstars like this at f/16.

This Fujinon XF 90mm f/2 R LM WR, along with the 50-140mm f/2.8 at 140mm, is Fujifilm's best portrait lens for their X-series of cameras. This 90/2 has flawless optics, great mechanics, super-close focussing and super-fast autofocus!

This is a tough all-metal lens, almost as well built as Nikon's world-leading 135mm f/2 DC, which also has superlative optics.

If you don't already have the 50-140mm f/2.8 and/or if you need an astronomy lens, this is Fuji's best.

This ad-free website's biggest source of support is when you get yours at Adorama, at Amazon or at B&H, or when you use any of these links to approved sources when you get anything. Please always use these links when getting anything so I can continue to share what I know. 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 are sealed, buy your 90mm lens elsewhere or at retail and you'll not only cheat me out of the work I've done here to help you, you take the significant risk of getting a customer return, a dropped lens, you might be missing accessories or get a sample used for store demos. Never buy at retail; all of my approved sources ship your lens from secure warehouses far away from customers or sticky-fingered salespeople.

Thanks for helping me help you!
