AI Verdict
A 6.1-ounce, f/2 prime lens with a 40mm view, ideal for Z-series users prioritizing portability and character over clinical sharpness.
This lens is a strong fit for Nikon Z-series photographers seeking a lightweight (6.1 ounces), compact prime for everyday use. Its f/2 aperture and 40mm focal length offer a versatile perspective and good low-light capability, especially for video, without weighing down the camera.
If you need uncompromising corner-to-corner sharpness wide open or a more robust build, look for S-line prime lenses with metal mounts and more complex optical designs.

Pros
- Weighs only 6.1 ounces (170g), making the camera less front-heavy for comfortable carrying.
- Autofocus system is fast, quiet, and accurate, even in low-light conditions.
- Features a 9-rounded blade diaphragm that produces a pleasing, natural background blur.
- Offers minimal focus breathing and smooth iris adjustments via the click-less control ring, beneficial for video recording.
- Dust and water-droplet sealed, providing some protection against the elements.
- The custom control ring can be assigned to adjust aperture, ISO, or exposure compensation.
Cons
- The lens features a plastic mount, which is a compromise in build quality compared to metal mounts.
- Image sharpness is noticeably soft in the corners at f/2, requiring stopping down to f/4 or f/8 for consistent sharpness across the frame.
- Does not include a lens hood, and the front is not designed with a bayonet mount, limiting hood options to screw-on types.
- Exhibits visible coma, making it unsuitable for astrophotography.
- Close-up performance at its minimum focus distance of 0.29m results in a low 0.17x magnification with reduced contrast and detail.
Dimension Scores
Delivers pleasing bokeh and center sharpness when stopped down, but exhibits corner softness at f/2 and visible coma.
Autofocus is fast, quiet, and accurate, handling challenging situations like low-light street photography.
Features minimal focus breathing, quiet autofocus, and a click-less control ring for smooth iris adjustments, making it well-suited for video recording.
Weighing only 6.1 ounces (170g) and being compact, it significantly reduces camera front-heaviness and is easy to carry.
Best For
- Street photography, due to its compact size and fast autofocus.
- Travel and everyday carry, as its light weight prevents camera front-heaviness.
- Casual portraits and candid shots with pleasing background blur.
- Video recording, thanks to minimal focus breathing and quiet operation.
Not Recommended For
- Astrophotography, due to clearly visible coma.
- Users who demand corner-to-corner sharpness at the widest aperture.
- Professional macro photography, given its 0.17x maximum magnification.
Watch Out For
- The lens mount is made of plastic, which might concern users accustomed to metal mounts on other lenses.
- Nikon does not include a lens hood, and there's no bayonet mount, meaning any hood must be screwed onto the 52mm filter threads.
- You'll see significant corner softness at f/2; achieving sharp results across the entire frame requires stopping down to at least f/4, and ideally f/8.
- There's clear focus shift if you're using apertures slower than f/5.6, so you might need to refocus after changing aperture.
- Close-up shots at the minimum focus distance lack contrast and fine detail, making it less ideal for detailed close-up work.

What Buyers Say
What's really interesting is how many users describe this lens as having 'character' or an 'analog look,' which sets it apart from the often 'clinical' sharpness of more expensive S-line lenses. People are consistently stoked about how light and small it is, making it a go-to for everyday shooting. The autofocus is surprisingly quick and quiet, even in dim light, which is a big win for its price point. However, don't expect razor-sharp corners at f/2; you'll definitely need to stop down for that. The plastic mount and lack of an included lens hood are common points of discussion, but most agree they're acceptable trade-offs for the price and size.
“Dude, this 40mm f/2 is my new favorite walk-around lens for my Z5. It's so tiny and light, my camera just feels balanced, not like it's dragging a brick on the front. Yeah, it's a little soft in the corners wide open, but for the price and how much I actually use it, who cares? The bokeh is creamy, and the AF is silent. Just wish it came with a hood, seriously.”
Common Praise
- It's incredibly light at 6.1 ounces, making the camera feel less front-heavy.
- The autofocus is fast, quiet, and accurate, even in challenging low-light conditions.
- Produces a pleasing, 'bloomy' background blur thanks to its 9-rounded blade diaphragm.
- The minimal focus breathing makes it a strong choice for video work.
- Offers a 'classic' or 'analog' rendering that some prefer over sterile sharpness.
- The price point is frequently mentioned as a major selling point for its capabilities.
Common Complaints
- The lens has a plastic mount, which feels less premium than metal.
- Corners are soft at f/2 and require stopping down to f/4 or f/8 for sharpness across the frame.
- No lens hood is included, and there's no bayonet mount for one.
- Visible coma makes it unsuitable for astrophotography.
- Close-up performance lacks contrast and detail at minimum focus distance.
- Some users experience focus shift when stopping down past f/5.6.
Ownership Tips
- You'll quickly learn to stop down to f/4 or f/5.6 for landscapes or group shots if you want sharp edges.
- The plastic mount, while initially a concern, holds up fine given the lens's feather-light 6.1-ounce weight.
- The lack of a lens hood is annoying; you'll probably end up buying a cheap screw-on one or just being careful.
- The 'character' of the lens, especially the bokeh, really shines through after using it for a while, giving images a distinct look.
- It truly excels as a 'lens cap' lens – always on the camera, ready to shoot because it's so unobtrusive.
Frequently Asked Questions

Is this lens good for video?

What is the maximum magnification of this lens?
The maximum magnification is 0.17x, which is not designed for dedicated macro photography.

Yes, the Nikon NIKKOR Z 40mm f/2 is dust and water-droplet sealed.
Buying Guide
When you're looking at a prime lens like this, you need to think about how you shoot. A fixed 40mm focal length means you'll be 'zooming with your feet,' which can push you to be more creative. The f/2 aperture is a big deal for low-light shooting and getting those blurry backgrounds, but understand that budget primes often make trade-offs in corner sharpness at their widest apertures to hit a certain price and size. Also, consider the build materials; a plastic mount isn't necessarily a deal-breaker for a lightweight lens, but it's something to be aware of.
40mm Focal Length
This is how 'zoomed in' your photos will be. 40mm is considered a 'normal' perspective, very close to how the human eye sees, making it versatile for everything from street scenes to environmental portraits without distorting proportions too much. It's wider than a classic 50mm but tighter than a 35mm.
f/2 Maximum Aperture
This number tells you how much light the lens can gather and how blurry you can make the background. An f/2 aperture is 'fast,' meaning it's great for shooting in dim light without cranking up your camera's ISO too high, and it allows for a shallow depth of field, making your subject pop against a soft, out-of-focus background.
Prime Lens
Unlike a zoom lens that lets you change focal lengths (e.g., 24-70mm), a prime lens has a fixed focal length. This often means it can be smaller, lighter, and optically sharper than a zoom at a similar aperture, but you lose the flexibility of zooming. You move your body to frame the shot.
Alternatives
If this lens doesn't quite fit, consider lenses with a wider maximum aperture (f/1.8 or f/1.4) for better low-light performance and more background blur, or look for lenses with an all-metal construction for enhanced durability, or primes designed for corner-to-corner sharpness even at their widest aperture.
