Fuji 27mm f/2.8  XF

Fuji Fujinon XF 27mm f/2.8 in black for X-mount cameras, also comes in silver (39mm filter thread, 2.7 oz./77.3g, 1.1'/0.34m close focus, about $450). enlarge. I got mine at Adorama; this link to it at Amazon is also a great place to get it. This free website's biggest source of support is when you use that or these links to approved sources when you get anything, regardless of the country in which you live — but I receive nothing for my efforts if you take the chance of buying elsewhere. Never buy at retail, since Fuji doesn't seal its boxes so you can't tell if it's a used lens or missing accessories. Thanks for your support! Ken.

This Fuji XF 27mm f/2.8 is a tiny perfect-normal (41mm equivalent) lens that works on Fuji's X-mount cameras.

While 50mm equivalent lenses are often too long, and 35mm equivalent lenses often too short, "perfect normal" lenses — lenses equal to the diagonal of the image sensor — are the perfect normal focal length. At 41mm equivalent, this funny-sounding 27mm lens is actually the one normal lens you might need for everything.

It's super small and light. I have lens caps bigger than this entire 27mm lens.

The only gotchas with this Fuji lens is that there is no instant manual-focus override and no aperture ring. You have to move a switch on your camera to get to or from manual focus mode, and move a dial on the camera to change the aperture.

The Fuji X-Mount Lenses are all extraordinary. What most photographers don't realize is that 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.

As expected, this lens is just about optically perfect, and it autofocuses amazingly fast.

Name

Fuji 27 4 front

Fuji 27/2.8.

Fuji calls this the Fujinon Aspherical Lens Super EBC XF 27mm f/2.8, or XF27mmF2.8.

Fujinon is Fuji's brand name for their lenses.

Aspherical means specially shaped lens elements for better sharpness.

Super EBC is Electron Beam Coating, also known as multicoating or HT-EBC coating.

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

39 means it takes 39mm filters.

Overall      performance      top

The Fuji XF 27mm f/2.8 ASPH is optically close to perfect, tiny and focuses super fast. It's a great little lens.

 

Auto and Manual Focus      performance      top

Autofocus is super-fast and always accurate.

You do have to move a switch on your camera to go between auto and manual focus.

Manual focus is by-wire, meaning the manual focus ring is merely an encoder that talks to a computer that moves the lens.

It's so fast its scary. I don't know of any lens-camera combination that's faster!

 

Bokeh      performance      top

Bokeh, the softness of out-of-focus areas, isn't significant with a wide, reasonably short lens like this.

Almost nothing is ever out of focus, and when it is, it's undistracting.

Color Rendition      performance      top

Color rendition is neutral, matching the other Fuji lenses.

La Virgen de Guadalupe, 10 September 2014. Fuji X-T1, f/2.8 at 1/125 at Auto ISO 500. full-resolution.

Distortion is invisible as shot as JPGs on my Fuji X-T1, which for all I know is correcting it automatically.

What little barrel distortion there is can be corrected for more critical use by plugging these figures into Photoshop's lens distortion filter. These aren't facts or specifications, they are the results of my research that requires hours of photography and calculations on the resulting data.

Ergonomics      performance      top

Fuji XF 27mm f/2.8

Fuji XF 27mm f/2.8 for X-mount cameras.

This lens is about the size of a body cap.

There are no controls other than this one control ring.

This focus encoder ring is relatively useless; manual focus is done by tapping the camera's AF button to focus and lock. The encoder ring is slow and silly.

There is no aperture ring. You have to use a dial on the camera to set it, or to set it to Auto aperture control for A and P modes

 

Falloff (darkened corners)      performance      top

Light falloff is completely invisible even wide open at f/2.8, as shot on the X-T1 which is probably correcting it automatically.

 

Filters, Use with      performance      top

There's no problem with vignetting, even with many, many stacked filters!

The lens glass is tiny and it could use a much smaller filter than it does. 39mm is a much larger filter than needed, but as the standard size for LEICA, Fuji chose to emulate LEICA and use the same size filter.

The filter ring doesn't rotate, but it does move in and out with the lens as it focuses.

 

Flare and Ghosts     performance      top

Ghosts

Ghost, 11:43 AM, 27 August 2014. Fuji X-T1 at Auto ISO 400, 24mm at f/16 at 1/350. bigger.

There's no problem with ghosts.

Even under the most devious conditions I could devise, all I got was one dim purple blob as seen here.

No problems here.

 

Lateral Color Fringes      performance      top

There are no lateral color fringes as shot on the X-T1 as JPGs, which is probably correcting any if there were any.

 

Macro      performance      top

It doesn't get very close. This is as close as it gets:

macro

macro

Crop from above 4 MP image at 100%. If this is 6" wide on your screen, the complete image would print at 25 x 17" (64 x 42 cm) at this same magnification.

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.

The Fuji XF 27/2.8 is super sharp.

It's always super sharp throughout almost all of the image at every aperture.

Only wide-open at f/2.8 are the farthest corners very slightly softer. They improve at f/4, and are as ridiculously sharp as the center at f/5.6. The only time this could ever be noticed is if you're shooting tests where the corners would actually be in perfect focus at f/2.8, which almost never happens, and even if it does, this lens is still sharp in the corners at f/2.8.

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 no spherochromatism (called color bokeh by hobbyists). This means that out-of-focus highlights remain neutral and don't take on slight color fringes.

 

Sunstars      performance      top

Sunstar, 11:43 AM, 27 August 2014

Sunstar, 11:43 AM, 27 August 2014. Fuji X-T1 at Auto ISO 400, f/16 at 1/350. bigger.

The 7-blade rounded diaphragm makes soft sunstars, if any.

There aren't any sunstars at large and medium apertures to about f/8 or f/11.

To see sunstars you should be stopped down to f/14 or f/16.

 

Recommendations       top

Intro   Specs   Performance   Recommendations   More

The Fuji XF 27mm f/2.8 ASPH is a fantastic little lens. It does everything I'd need it to do with superb optics and tiny size. I often prefer fixed lenses over zooms.

This 27/2.8 is a superb lens and I highly suggest you get one to throw in your bag with your Fuji X-mount camera.

However, if you want to get this lens to turn your Fuji X-mount camera into a tiny pocket camera, get an X100T (or old X100S or X100) instead of this lens. These X100 cameras have an even faster fixed lens in a package that's even smaller than an interchangeable-lens X-mount camera, and the X100 series has a much better combined optical/electronic finder superior to anything else from Fuji.

Get this lens to add-on to a Fuji X-mount camera, but if your plan is to get a tiny walk-around lens, get an X100T instead of this lens.

There are no better lenses to use on the Fuji system at any price. Forget slumming with LEICA or other off-brand lenses and adapters; you can't get anything sharper and any other lens won't autofocus or autoexpose or log data or be optimized by the camera's DSP, and no other lens will have a diaphragm that opens and closes automatically as needed for focus and shooting.

If you've found my research here helpful, my support to run this free website comes from when you use these links to approved sources, especially this link to it at Adorama and and this link to it at Amazon, when you get anything, regardless of the country in which you live. 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 which is sealed, buy your 27mm 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 or been used for store demos.

Thanks!

Ken.
