Lab Test Results

The Fujinon XC 16-50mm ƒ/3.5-5.6 OIS lens is a versatile, compact X-mount zoom lens from Fujifilm. Sold either as a standalone lens or as part of the kit for the Fujifilm X-M1 and X-A1 mirrorless cameras, this lightweight lens provides a 35mm equivalent focal length range of 24-76mm, for wide-angle shots to portraits and everything in between. The lens also includes optical image stabilization technology to help reduce blurring from camera shake at slower shutter speeds. With a variable aperture only going as wide as ƒ/3.5, the addition of OIS is certainly nice to have.
A fairly straightforward lens, it does feature 3 aspherical elements and 1 ED element like its more expensive sibling, the XF 18-55mm ƒ/2.8-4 lens, as well as Fuji's EBC coatings for reduced flare and ghosting. It's also worth pointing out that this lens, unlike most of Fuji's lenses, does not have a manual aperture ring, and so users of the X-Pro1 and X-E1 cameras should update their cameras' firmware in order to control the aperture via the camera.
As a standalone lens, the Fujinon XC 16-50mm ƒ/3.5-5.6 OIS is available in either a black or silver finish for around $399 -- Adorama, Amazon (black, silver), B&H (silver) -- and includes front and rear lens caps. Note: Our test lens was included as part of an X-A1 kit, which included a petal-shaped, bayonet-mount lens hood. However, in the standalone retail copy of this lens, a hood does not appear to be included, despite the owner's manual indicating otherwise. Check with your retailer of choice to see if a lens hood is included.
Traditionally, kit lenses have gotten a bad rap for underwhelming performance, particularly in sharpness. However, that trend seems to be changing these days, and the new Fujifilm 16-50mm lens is no exception. This lens produces very sharp images, even wide-open, and throughout the entire zoom range. Corner softness is also quite insignificant -- even fully wide at 16mm -- making it a great landscape lens, as well as a general-purpose street and portrait lens at the longer focal lengths. Diffraction limiting softness is equally minimal, with only minor softness appearing around ƒ/22 (ƒ/16 shows just a hint of softness, too). Overall, very impressive results from an inexpensive kit zoom lens!
OK, well, trade-offs have to be made when designing an affordable lens, and in the case of the Fuji 16-50, it comes by way of chromatic aberration. Thankfully, it's a not a huge compromise after all. Wide open at 16mm, the lens is really very low CA on average, but out in the corners we see some fairly strong CA -- notceable blue/purple and light green fringing -- hitting over 900ths of a percent of frame height, but CA is noticeably reduced by stopping down the aperture. Also, the Fuji JPEG processing does a great job at removing this CA in-camera.
However, the story really changes at the longer focal lengths we tested (24mm, 35mm and 50mm) -- very low CA. On average, the CA at 25-35mm is practically nonexistent, and 35mm in particular shows excellent CA across the entire frame. At 50mm, there's a little more CA on average, though it's still quite low, and there is a little uptick in CA when you stop down to the really narrow apertures.
This lens also shows impressive results for controlling vignetting, even at the wide focal lengths. Interestingly, at 16mm, we saw lower vignetting at ƒ/3.5 than at ƒ/5.6, which increased to around a still-very-low 0.25EV of light loss. At the other focal lengths and apertures, vignetting was all-around much lower and never displayed more than 0.25EV of light loss. The longer focal lengths, especially, were well under that level.
The Fuji 16-50mm lens also does very well at controlling distortion. On average, we saw just a slight amount of barrel distortion at the wider end of the focal lengths, which is not unexpected. However, when you zoom to 24mm and longer, distortion becomes practically nonexistent!
Note: It should be noted that the X-E1, our Fuji test camera, does feature in-camera correction of CA, vignetting and distortion, and it's important to note that our results here were taken from RAW files. However, when converted with Adobe Camera Raw, as it our usual procedure, ACR carries over these in-camera corrections. It was only by converting the same RAW images with DCRAW (which does not convert the images with these corrections) that we were able to confirm this.
In our handling of the Fuji 16-50mm, the autofocusing performance was excellent. The lens focused very quickly, taking well under a second to rack from minimum focus distance to infinity thanks to an electrical "high-precision stepper motor." Of course, there is also manual focusing with a focus-by-wire system, and as such, the smoothly rotating focus ring has no stops at either end. There is also no focus distance window on this lens, with the information about focusing displayed via the camera.
The 16-50mm kit lens isn't great for macro photography, offering just 0.15x (1:6.7) maximum reproduction ratio at 50mm at a minimum focusing distance of 40cm / 15.7 inches, and the minimum focusing distance at 16mm is still a fairly long 30cm / 11.8 inches.
Build Quality and Handling
The Fuji 16-50mm lens saves a lot of weight and cost by being constructed almost entirely of polycarbonate plastic, including the lens mount. However, it feels very well-built and solid with the lightweight design balancing nicely on equally lightweight Fujifilm cameras like the X-E1, for example.
The focus and zoom rings both rotate smoothly and are also made of plastic with a deep-ridged texture for an easy grip. The zoom ring itself rotates less than 90 degrees. The zoom ring is also a little on the firm side to rotate, however, combined with the lightweight and minimally-extending barrel design (adding only 1.5 inches of extra length), this ensures that lens creep should be a non-issue.
The rest of the exterior is fairly simple, with only a set of focal length markings -- no focus distance window or OIS switch, however (that's controlled via the camera). As mentioned above, there is no manual aperture ring like many of Fuji's other lenses, so aperture is completely controlled from the camera itself. Fuji notes that users of the X-Pro1 and X-E1 cameras will need to ensure they have the latest firmware to enable camera-based aperture control on this and other Fuji lenses that lack an aperture ring.
On the inside of the barrel sit 12 elements in 10 groups with 3 aspherical elements and 1 extra low dispersion element. The elements also feature Fuji's EBC coatings to help reduce flare and ghosting. The lens has 7 rounded diaphragm blades for nice out-of-focus backgrounds.
The most obvious alternative is the other Fujifilm wide-to-medium-tele zoom lens, the XF 18-55mm ƒ/2.8-4 R LM OIS. This lens features a similar focal length range, although sacrificing a couple millimeters on the wide end for a bit more reach on the tele side. In terms of image sharpness, the 18-55mm shows similarly impressive results, although there's a bit more chromatic aberration and vignetting. The biggest difference is on the physical side with a faster variable aperture range that opens to a very useful ƒ/2.8. It's also constructed out of metal -- both the barrel and lens mount. The big downside is the large jump in price at around $695.
There aren't really many other alternatives for the Fuji X-Mount system apart from Fuji's own offerings and a couple of Carl Zeiss primes. As for an alternative to the 16-50mm zoom lens, one could opt instead for a set of primes: the 14mm or 18mm Fuji prime for the wide-angle, the Fuji 23mm, 27mm or 35mm primes for the middle focal lengths and then either the 56mm ƒ/1.2 or 60mm macro lens for a bit of the medium-tele end. However, this is not only a lot of extra lenses to carry around, it's also some serious money (i.e. the 56mm ƒ/1.2 lens is $1000 by itself).
The Fujinon XC 16-50mm ƒ/3.5-5.6 OIS lens is an impressive optic for an affordable and basic kit lens. With excellent sharpness, low vignetting and distortion and well-controlled CA, there's a lot to love with this kit lens. The image stabilization also worked generally well, matching the Fuji advertised 2-2.5 stops at 50mm, but was a little less impressive at the wider end (however, the wider you shoot, IS becomes less necessary, as you can shoot at slower shutter speeds much easier).
All in all, if you're thinking of buying a Fuji X-M1 or X-A1, you'll get a very solid, versatile and well-performing lens in your kit. And if you're an existing Fuji X-series owner in need of a budget-friendly, lightweight zoom lens and don't need an ƒ/2.8 aperture, the Fujinon XC 16-50mm ƒ/3.5-5.6 OIS is a solid choice.
The VFA target should give you a good idea of sharpness in the center and corners, as well as some idea of the extent of barrel or pincushion distortion and chromatic aberration, while the Still Life subject may help in judging contrast and color. We shoot both images using the default JPEG settings and manual white balance of our test bodies, so the images should be quite consistent from lens to lens.
As appropriate, we shoot these with both full-frame and sub-frame bodies, at a range of focal lengths, and at both maximum aperture and ƒ/8. For the ''VFA'' target (the viewfinder accuracy target from Imaging Resource), we also provide sample crops from the center and upper-left corner of each shot, so you can quickly get a sense of relative sharpness, without having to download and inspect the full-res images. To avoid space limitations with the layout of our review pages, indexes to the test shots launch in separate windows.

Fujinon XC 16-50mm f/3.5-5.6 OIS User Reviews
10 out of 10 points and recommended by joe88 (44 reviews)excellent correction of CAs from 24 to 50 mm very good sharpness with f 5.6-11- plastic housing - lack of aperture ring - 16mm distorsion
Unbelievable bad recensions - what a shame ! Perhaps a Monday production ?reviewed March 17th, 2022 (purchased for $100)
Zoom lenses are obviously not so sharp as single lenses - okay.
But this sometimes underrated lens ist for this price a good match for FUJI system cameras.
Its sharpness and correction is better than the 2.8-4/18-55 lens, which is much more expensive.
For big posters you can improve sharpness by PhSh and interpolation, and sharpen it once more.
The lack of aperture ring is sometimes a small problem. Only 16mm must be corrected in any cases, isn't it?
A very good lens - much more better than the standard zoom lenses of the 3 big professional brands with fat CAs in corners - and overrated test results !!! So this Lens, and the old Panasonic 14-45, and Pentax 18-55 WR, and Samsung NX 20-50 are the better 4 standard lenses for digital photography ! In summary - actually, FUJI is the best alterativelesss system in dig. photography because of its lenses, the high ISO performance and the value / prices. As former teacher of photogr. I'm using x-e1 and x-T100 with changed programs (highest color saturation, highest sharpness and highest contrast) for totally 700.- (2 bodies and the 16-50 lens, all new), additionally many vintage lenses with adapters - which could concurate with serveral full size cameras of other brands, especially my razor sharp x-T100 with old FUJINIONs!!!
9 out of 10 points and recommended by iborramira (1 reviews)Relación calidad-precio inigualable. Absolutamente extraordinario para su precio y mucho mejor que otros objetivos mucho más caros de otros sistemas.Montura de plástico. Ausencia de anillo de diafragmas. Creo que podría haberse diseñado algo más compacto, a la vista de lo logrado en su hermano, el XC 15-45 mm.
No entiendo las bajas valoraciones hechas por algunos usuarios a esta lente. Es, sin la menor duda, el mejor kitero de todos los sistemas que he tenido (que son todos los existentes hasta el FF) con un rango focal similar. Su rendimiento a plena apertura es excepcional, superior a cualquier otro zoom similar.reviewed July 24th, 2019 (purchased for $170)
3 out of 10 points and not recommended by BielsasBucket (2 reviews)Light, cheap, quiet focusing. Sharp in the center.Not sharp anywhere else.
It may just be the copy I had, but the edge sharpness of this lens is truly awful. "Worse than a Tamron superzoom" awful. It starts about a third of the way from the center (horizontally) and gets worse from there. Details start to smudge and smear. Even deliberately out of focus areas get an 'oval ring' bokeh which is really nasty to look at and ruins the image.reviewed October 31st, 2018
Obviously this lens is built to a price, so I wouldn't expect it to be a Summicron. I think the problem is probably in the quality control area, as others' experiences and reviews seem to be better than mine. After returning my copy I didn't want to go through it all again trying to get a good copy. I would recommend that you save up and get the 18-55 XF zoom instead.
8 out of 10 points and recommended by eduardok72 (1 reviews)Great image quality, low weight, small size, sharpness wide open.imaging stabilization is not that great as its rated here at imaging resource.
despites imaging resource's review about image stabilization, better stop down to minimum 1\30s to get the best sharpness on this lens. 1/15s at 50mm when stabilization is rated as 2.5 stops is a little too much for this lens. I have compared this lens with XF18-55 and the XF is noticeable better at low light and slow shutter speeds.reviewed September 24th, 2017
8 out of 10 points and recommended by MadPixel (1 reviews)price, really sharp, good AF, ultralight and compact, absolutely excellent wide zoom range – from 16mm, good contrast matching fuji camera settingsin this price any and not so much, if so overall
I got my for $100 used, but like a new or just not used from somebody kit, with hood (lucky), and I bought it just for have fast my first lens when I waited my X-E1. I'm very impressed with overall output from this lens, I don't like kit zooms but this one is good enough or just good lens. Comparing to famous Konica Hexanon AR 40mm 1.8, I must say XC 16-50mm is really sharp and in center mostly - following my simple tests - much sharper! However, this is subjective feeling, because I like photos Hexanon look more. My rate is 8/10 only because I never had perfect lens, but in this price should be 10/10reviewed May 30th, 2016 (purchased for $100)
8 out of 10 points and recommended by chrisjoerg (2 reviews)light, small, sharp, unobstrusive;is not considered to be a pro lens, does not impress, no 2.8 (but we knew that before)
My background is beeing a Canon shooter, who now completed selling all his beloved Canon gear because of a boring cheap Fuji X-A1 with this cheap and boring lens. And that means something. I had very good canon glass like the 70-200 f2.8 IS mk II and so on. Also bad Canon glass like the intolerable 24-105 f4 IS. This lens is in terms of image quality, lightness and price just stellar. Really, I sold my Canon gear because of this, and I loved the Canon gear, but this, over all, is better or on par for a fraction of the weight and price.reviewed January 27th, 2016 (purchased for $120)
Maybe you want to have a look at my articles about this lens mounted on a Fuji X-A1 on my website:

I really recommend this lens, see what you can do with it!
8 out of 10 points and recommended by waterfoot (3 reviews)Very light, inexpensive, (mainly) sharp, useful zoom rangePlastic mount a little loose, my copy is soft on right edge of image
This came with a X-M1 for a total price of £270, so it's a bit unfair to be over-critical, but for those who may want to buy this lens separately it's best to be brutally honest.reviewed March 17th, 2015
Firstly the build is generally ok but mine is a bit loose in the mount, allowing movement when zooming (the zoom action is a bit stiff).
Secondly mine appears to be decentered, with a soft right side mostly towards the top right corner which is a bit disappointing.
I bought the X-M1 kit as a lightweight travel camera and despite my criticisms the lens is up to the job, out-performing almost all kit lenses I've used even with the decentring so another copy would probably be even better. But it really doesn't deserve "top marks" in any category other than "value for monyey".
Bottom line: not stellar by any measure but a solid performer at a bargain price when bought with a kit - bud I would be unhappy had I paid the $400 asking price for the retail version.
10 out of 10 points and recommended by arldite1066 (3 reviews)very sharp for price, light weight
For a kit lens it is excellent value for moneyreviewed January 16th, 2015 (purchased for $99)
10 out of 10 points and recommended by Klicko Orange (3 reviews)quick to focus, sharp (edge to edge), light weight and comes as a kit (meaning free with X-m1 and X-a1)non for the price
This is the best entry level kit lens ever made.reviewed April 8th, 2014
Mine is only very slightly soft in the extreme right corner at 16mm wide open. But even then it's nothing to complain about as it is more than acceptable.
Wish it ended at F/4.5 at the long end or F/2.8 in the wide end but then the price would be more expensive.
