Introduction<\/span><\/h2>\n

Just two years ago, finding a true ultra wide-angle prime for APS-C cameras felt like chasing a unicorn. But that\u2019s changed fast. A wave of new releases\u2014many from Chinese lens makers\u2014has opened up a lot of new options for APS-C shooters. Now, 7Artisans joins the mix with its 10mm f\/2.8, a lens that promises a lot for its price. Can it really stand out in this crowded new field? Let\u2019s find out.<\/p>\n

\"camera-icon2\"I tested this lens on a Nikon Zfc<\/a>.

Handling and Build Quality<\/span><\/h2>\n

The 7Artisans 10mm f\/2.8 is an autofocus lens made entirely of metal. The lens doesn’t have any image stabilisation, though at its focal length, it\u2019s hardly necessary. For being a metal lens, it feels light, while the metal adds a little to its weight.<\/p>\n

\"\"<\/p>\n

The build feels tight and solid. It has a sleek design, although it is on the larger side of the scale for an APS-C 10mm f\/2.8 lens.<\/p>\n

There is an AF-MF switch on the lens barrel. The large metallic focusing ring turns smoothly, and in addition to focusing, it can be set to control aperture values, exposure compensation, or be disabled. The focus ring is not mechanically coupled and changes the focusing by wire. The autofocus is quick, precise, and silent.<\/p>\n

\"\"<\/p>\n

The mounting plate has electronic contacts for data transfer, aperture control, and autofocus, as well as a USB-C port for firmware updates. A sealing gasket around the mount helps protect the lens from dust and moisture.<\/p>\n

\"\"<\/p>\n

In addition to front and rear caps, a petal-shaped, sturdy, hard plastic lens hood is included in the box.<\/p>\n

Sharpness (Infinity)<\/span><\/h3>\n

For the infinity sharpness test, we look at three areas of the image, centre, mid-frame, and corner, see highlighted areas in the image below!<\/span><\/p>\n

Sharpness in the centre is good wide open, very good at f\/4, and excellent from f\/5.6 onward. The midframe trails by about a stop: it\u2019s OK at f\/2.8, good at f\/4, very good at f\/5.6, and close to excellent from f\/8, though it never quite reaches the same level as the centre. The corner is noticeably weaker at f\/2.8\u2014hardly OK\u2014and improves only gradually with stopping down. It reaches OK by around f\/4, becomes good at f\/5.6, and approaches very good from f\/8. It improves a little further at f\/11, where we get the best across-the-frame sharpness. Also positive is that the contrast is strong at all apertures.<\/p>\n

There is visible colour fringing at all apertures, which reduces apparent sharpness, but it\u2019s easily corrected in Lightroom or Photoshop, and doing so is strongly recommended.<\/p>\n

Sharpness (Close-up)<\/span><\/h3>\n

Close-up sharpness is just OK wide open; it gets a lot better at f\/4 and comes up to a good level, and becomes very good at f\/5.6. It keeps the very good sharpness up to f\/11, where the diffraction lowers the sharpness a little, which becomes more obvious at f\/16.<\/p>\n
