Deep Dive: Understanding the Key Differences
Focal Length and Versatility
The most immediate difference between these two lenses is their focal length range. The Nikon offers a broader 24-120mm range, while the Sigma provides 24-105mm. That extra 15mm on the Nikon might not sound like much, but in practice, it makes a noticeable difference.
I discovered this during a recent trip to New York City. While shooting street photography with the Nikon 24-120mm, I found myself frequently zooming past 105mm to capture distant architectural details and candid moments from a comfortable distance. When I switched to the Sigma 24-105mm for a day, I definitely missed that extra reach, especially when I couldn’t physically move closer to my subjects.
However, the Sigma’s more conservative range allows for slightly better optical performance across the zoom range, as we’ll explore later.
Build Quality and Handling
Both lenses feature solid construction with weather sealing, but there are notable differences in their design and handling.
The Nikon 24-120mm feels like a premium Nikon product – it’s well-balanced on Nikon bodies, has smooth zoom and focus rings, and exudes quality. During a rainy day shoot in Seattle, I appreciated its weather sealing as it continued to perform flawlessly despite the conditions.
The Sigma 24-105mm, being part of Sigma’s prestigious Art line, boasts exceptional build quality with a metal mount and high-quality plastics. It feels slightly heavier than the Nikon, but that’s not necessarily a bad thing – it gives the lens a substantial, professional feel. I’ve used it in dusty conditions in Arizona, and its weather sealing held up perfectly.
One ergonomic difference I noticed: the Nikon’s zoom ring is slightly wider and more textured, making it easier to adjust with gloves on – a consideration if you shoot in cold climates.
Optical Performance and Image Quality
This is where things get interesting. Both lenses produce excellent images, but with some key differences:
Sharpness: The Sigma 24-105mm Art is renowned for its sharpness, especially in the center of the frame. When I tested both lenses side by side on my Nikon Z7 II, the Sigma showed slightly better sharpness at wider apertures, particularly at the 24mm and 105mm ends. The Nikon 24-120mm is no slouch either, delivering excellent sharpness throughout its range, but it requires stopping down to f/5.6 or f/8 to match the Sigma’s wide-open performance.
Chromatic Aberration: The Sigma’s superior optical design, with its FLD (Low Dispersion) and SLD (Special Low Dispersion) elements, results in better control of chromatic aberration. During high-contrast situations – like shooting backlit portraits – I noticed less purple fringing with the Sigma, even when viewing images at 100%.
Vignetting and Distortion: Both lenses exhibit some vignetting, especially at wider apertures, but the Nikon shows slightly more pronounced vignetting at 24mm. Fortunately, modern cameras and software can easily correct this.
Distortion is well-controlled on both lenses, with the Sigma showing slightly less barrel distortion at 24mm and the Nikon having a slight edge at the telephoto end.
Bokeh Quality: For a walk-around lens, bokeh quality might not be your primary concern, but both lenses deliver pleasing background blur when shooting portraits. The Sigma produces slightly creamier bokeh in my experience, particularly when shooting at the 105mm end.
Autofocus Performance
Both lenses feature fast and accurate autofocus, but with some differences worth noting:
The Nikon 24-120mm uses Nikon’s Silent Wave Motor (SWM), which is fast and nearly silent. During a wedding I shot last May, the lens locked onto subjects quickly and tracked moving subjects with impressive accuracy.
The Sigma 24-105mm employs Sigma’s Hyper Sonic Motor (HSM), which is equally fast and perhaps even quieter than the Nikon’s. In low-light situations, I found the Sigma to hunt slightly less, though the difference was minimal.
For video work, both lenses are suitable, though the Sigma’s quieter autofocus might give it a slight edge for recording audio.
Image Stabilization
Both lenses come equipped with effective image stabilization, but they use different technologies:
The Nikon features its second-generation Vibration Reduction (VR II) system, which Nikon claims provides up to 4 stops of stabilization. In my real-world testing, I found this claim to be accurate – I was able to get sharp handheld shots at 1/15s at 120mm, which is impressive.
The Sigma uses its Optical Stabilizer (OS) system, which Sigma claims provides up to 4 stops of stabilization. My testing showed similar performance to the Nikon, with sharp handheld results at slow shutter speeds.
For video, both stabilization systems work well, though I noticed the Nikon’s VR produced slightly smoother footage when walking while recording.
Real-World Performance: Which Lens Shines Where?
Landscape Photography
For landscape photography, both lenses perform admirably, but with some differences:
The Nikon’s wider 24-120mm range gives you more flexibility for capturing both expansive vistas and distant details. During a sunrise shoot in the Grand Canyon, I appreciated being able to go from 24mm for the grand vista to 120mm to isolate a distant rock formation without changing lenses.
The Sigma, while offering less reach, delivers slightly better sharpness across the frame, especially when shooting at wider apertures. This makes it an excellent choice for landscape photographers who prioritize edge-to-edge sharpness.

Portrait Photography
For portraits, both lenses work well, but with different strengths:
The Sigma 24-105mm produces slightly creamier bokeh and better subject separation, making it ideal for environmental portraits where you want your subject to stand out from the background. I used it for a family portrait session last month, and the results were stunning – sharp subjects with beautifully blurred backgrounds.
The Nikon’s extra reach at 120mm provides more flattering compression for headshots, and its slightly shorter minimum focusing distance allows for closer portraits. During a corporate headshot session, I found myself frequently using the full 120mm range to capture flattering portraits with pleasing compression.
Travel Photography
As a travel photographer, I’ve used both lenses extensively on various trips:
The Nikon 24-120mm’s versatility makes it an excellent travel companion. Its broader focal range means you’re less likely to miss shots because you don’t have enough reach. During a trip to Italy, I used it for everything from wide architectural shots to details on distant cathedrals, all without changing lenses.
The Sigma 24-105mm, while offering less reach, is slightly more compact and delivers consistently excellent image quality. On a recent trip to Japan, I appreciated its performance in low-light situations, from bustling Tokyo streets to serene temples in Kyoto.
Event Photography
For events like weddings or parties, both lenses have their strengths:
The Nikon 24-120mm’s versatility makes it a great single-lens solution for events where you can’t change lenses frequently. I shot an entire wedding with just this lens and was impressed by its ability to capture everything from wide group shots to intimate moments from a distance.
The Sigma 24-105mm’s superior low-light performance and autofocus make it excellent for indoor events with challenging lighting. During a dimly lit reception, it consistently delivered sharp images where other lenses might have struggled.
