We Review the Sigma 10-18mm f/2.8 DC DN Contemporary Lens for Fujifilm X Mount

Sigma continues to develop their line of small, quick, budget-friendly lenses for APS-C cameras. The Sigma 10-18mm f/2.8 DC DN lens is their newest providing, and it does certainly have quite a bit to supply photographers searching for a wonderful and quick extensive angle zoom that will not break the finances. 

So Very Small

The Sigma 10-18mm f/2.8 DC DN is extraordinarily compact. In response to Sigma, it is “the world’s smallest and lightest ultra-wide angle zoom lens for APS-C cameras,” as of October 2023. It actually is the smallest extensive angle zoom with a set f/2.8 aperture I’ve ever used, and at 260 grams, the burden was barely noticeable after I connected it to my Fujifilm X-T5. The ten-18mm (35mm equal 15mm-27mm) focal size is certain to attraction to many photographers together with these capturing landscapes, road, architectural, and journey genres, in addition to those that need an awesome lens for vlogging. 


The autofocus, as with all the earlier Modern lenses I’ve examined, is excellent for each nonetheless and video capturing. I examined the 10-18mm on the Fujifilm X-T4 and X-T5, with glorious outcomes on each cameras, though the efficiency on the X-T5 is best, which is to be anticipated. The lens locks on to faces with ease and didn’t give quite a lot of false positives when utilizing eye detect autofocus. The autofocus efficiency rivals a few of my rather more costly Fujifilm lenses. When capturing video and zooming, the main focus adjusts somewhat shortly and locks on, though there may be some focus respiration. 

Construct High quality and Dealing with

The construct high quality can be on par with different lenses in Sigma’s Modern line, and contains a steel lens mount which has a rubber gasket across the barrel for climate resistance. The gasket across the mount is the extent of the climate sealing, nonetheless, so though the 10-18mm is designed to withstand moisture, keep in mind that there aren’t any gaskets positioned internally across the zoom or focus rings. The zoom mechanism is exterior, and have to be zoomed “out” to succeed in 10mm, which is a bit complicated when first utilizing the lens. The ten-18mm doesn’t have a steel zoom barrel, and as a number of the Modern lenses have a big, steel focusing ring, the 10-18mm does really feel extra plasticky than the mounted focal size lenses within the line, though it’s on par with the 18-50mm f/2.8 when it comes to construct high quality, and it does not really feel cheaply made.

The zoom ring is just not massive, however straightforward sufficient to seek out with one’s palms when trying by way of the viewfinder. The handbook focus ring, nonetheless, is simply too slim, which makes it not possible to show the focusing ring with out your fingers additionally touching the lens barrel itself. This isn’t a significant problem, however for individuals who do a majority of handbook focusing it’s one thing price noting, and a criticism I’ve had with different lenses in Sigma’s Modern line.

Lastly, there isn’t a bodily aperture ring, which is, after all, a deal-breaker for some Fujifilm customers. For these of us who don’t thoughts utilizing command dials for aperture and shutter velocity management, or who’ve a Fujifilm digital camera with out conventional dials, that is after all a non-issue. 

Picture High quality

In my testing, the lens performs finest at 10mm and f/5.6. Within the accompanying video, I present samples at each 10mm and 18mm with various apertures, for these . At 10mm and f/2.8, picture high quality is superb within the middle and acceptable on the corners. There’s additionally some shade fringing, which was obvious at 10mm and 18mm, whatever the aperture I used. As is to be anticipated with a large angle lens, there may be additionally vignetting within the corners. When capturing into direct solar, there may be some flaring, however it’s well-controlled and didn’t current a significant problem in my time utilizing the lens.

Placing apart take a look at charts and pixel peeping, the Sigma 10-18mm offered glorious leads to a wide range of lighting situations and conditions. When visiting a neighborhood museum with my son, I used to be in a position to seize photographs in poorly lit and cramped rooms utilizing the quick f/2.8 most aperture and 10mm focal size. The colour, distinction, and element are all excellent. My son and I additionally took the 10-18mm exterior on a shiny day to {photograph} a neighborhood cathedral, and outside I used to be very happy with the colour rendition in Fujifilm’s commonplace Provia movie simulation mode. Since those that are utilizing a Fujfilm digital camera will little question use their digital camera’s glorious native movie simulations, myself included, I imported most of the pictures into Seize One, the place I did a fast edit which included eradicating undesirable vignettes, adjusting the shadow and spotlight element, and making use of a few of my favourite movie sims. One of many advantages of utilizing the 40-megapixel X-T5 is the power retain a considerable amount of shadow and spotlight element, which made modifying the pictures a straightforward and pleasant process. 


The Sigma 10-18mm f/2.8 DC DN provides one other glorious choice to their rising line of finances pleasant, compact, high-quality lenses. For anybody capturing with an APS-C sensor digital camera, these lenses are very enticing, particularly for the worth. I do really feel that the 10-18mm, nonetheless, represents a small compromise relating to picture sharpness, relying on the focal size and aperture used, nonetheless, this was not noticeable after I was utilizing the lens in a real-world context. For these searching for an inexpensive, quick, wide-angle lens, the 10-18mm ought to actually be in your quick record.
