Anyone who has been looking at new full-frame lenses over the past few years will probably have noticed a clear trend: wider apertures, higher sharpness and, unfortunately, more and more weight. Many modern lenses now weigh 500 grams or more, quickly making even relatively compact cameras feel front-heavy.
The new 7Artisans AF 40mm F2.5 LITE takes a completely different approach. At only around 90 grams, it is one of the smallest autofocus lenses available for full-frame cameras. Despite its tiny size, it still features an aperture ring, an AF/MF switch, a customizable function button and even a USB port for firmware updates.
At around €140, that almost sounds too good to be true. I’ve spent some time using the lens on Nikon Z cameras and came away pleasantly surprised. However, this tiny 40mm isn’t without its weaknesses.
Build Quality and Features
The biggest advantage becomes obvious as soon as you take the lens out of the box: it really is tiny. Even on a Nikon Z6III, it almost looks like a pancake lens and barely adds anything to the overall size of the camera. If you prefer travelling light or simply want a setup you’re more likely to carry with you, there’s a lot to like here.
Despite its compact design, 7Artisans hasn’t stripped the lens down to the bare minimum. You get a nicely clicked aperture ring, a dedicated AF/MF switch and a customizable Fn button. Controls like these are far from standard at this price point. For comparison, the Nikon Z 40mm F2 offers a slightly faster maximum aperture, but doesn’t have an aperture ring, AF/MF switch or function button.
Of course, you can also see where 7Artisans has saved some money. The body is made almost entirely from plastic and doesn’t feel particularly premium. Considering the extremely low weight, however, that’s hardly surprising. On the positive side, the lens does have a metal mount, and underneath a small cover you’ll find a USB port for firmware updates. We’ve seen this solution from quite a few Chinese lens manufacturers by now, and I still think it’s a very practical approach.
Image Quality
Image quality was probably where this little 40mm surprised me the most. Center sharpness is already impressively high at the maximum aperture of F2.5. For a lens in this price range, I honestly expected a little less.
The sweet spot seems to be around F5.6. At this aperture, sharpness improves noticeably towards the corners while many of the optical weaknesses become much less apparent. Chromatic aberrations are barely an issue anymore and vignetting is significantly reduced as well.
Vignetting, however, is one of the lens’s biggest weaknesses at F2.5. The corners are visibly darker when shooting wide open. How much this matters depends heavily on the subject. With portraits, it can be relatively unobtrusive and may even contribute to the look of the image. For architecture and landscape photography, however, I would have preferred more even illumination across the frame.
Backlight performance isn’t exactly one of the lens’s strengths either. Shooting directly towards bright light sources can noticeably reduce contrast, and fairly obvious flares can appear. The included lens hood helps to reduce this somewhat, but it doesn’t eliminate the effect completely.
The bokeh, on the other hand, is quite pleasing. At closer distances, you can achieve some nice subject separation, although backgrounds don’t look quite as smooth as they do with considerably more expensive lenses. With a minimum focusing distance of 40 centimeters, close-up photography is rather limited. For portraits and general photography, however, it still works perfectly well.
Real-World Experience
In everyday use, it quickly becomes clear where the real strength of this lens lies. It’s not about maximum aperture or perfect optical performance. It’s about combining an extremely low weight with simple, practical handling.
I particularly enjoyed using the lens while walking around Hamburg and on family trips. The camera remains pleasantly light and unobtrusive, while the 40mm still delivers image quality that is more than sufficient for everyday photography and a wide range of subjects.
Personally, I would probably pair the lens with one of Nikon’s smaller Z cameras rather than a larger body like the Z6III. Its compact dimensions simply make more sense as part of a small and lightweight setup. If you already own several fast prime lenses, the 40mm probably won’t become your main lens. But as a lightweight everyday option or an affordable entry into prime lenses, I can definitely see the appeal.
7Artisans AF 40mm F2.5 LITE Review: Conclusion
The 7Artisans AF 40mm F2.5 LITE isn’t trying to be a high-end prime lens, and that’s exactly where its strength lies. For around €140, you get an extremely compact full-frame autofocus lens with surprisingly good sharpness, useful controls and dimensions that you quickly learn to appreciate in everyday use.
Of course, there are compromises. The plastic construction feels fairly basic, vignetting is clearly visible when shooting wide open and flare can become an issue in difficult lighting conditions. If you can live with those limitations, however, the lens offers very good value for money.
Personally, I’d love to see 7Artisans take this concept further and perhaps offer a more premium metal version in the future. Even in its current form, though, the AF 40mm F2.5 LITE is a good reminder that a capable full-frame lens doesn’t necessarily have to be big, heavy or expensive.
