Optical Stabilization

Both the Nikon DX 10-24mm f/3.5-4.5 and the Sigma 10-20mm f/3.5 lack optical stabilization. While optical stabilization is less critical for wide-angle lenses, it can still be beneficial in certain situations, such as handheld shooting in low-light conditions or when recording video.

Despite the absence of optical stabilization in both lenses, it’s essential to be cautious with shutter speeds when using them handheld, particularly in low-light situations. Modern cameras with in-body image stabilization (IBIS) can effectively work with wide-angle lenses like these to minimize the effects of camera shake, even without built-in optical stabilization. Additionally, using a tripod or a fast lens with a larger aperture can be more effective tools for achieving stability and sharpness when shooting with wide-angle lenses.

In conclusion, neither the Nikon nor the Sigma offers superior optical stabilization, as both lenses lack this feature. However, depending on your camera and shooting situation, other stabilization methods such as IBIS, tripods, or faster lenses can still help achieve sharp images and smooth footage without the need for optical stabilization in the lens itself.

The Nikon DX 10-24mm f/3.5-4.5 and Sigma 10-20mm f/3.5 both exhibit chromatic aberration, but the severity and behavior differ.

For the Nikon lens, chromatic aberration is most noticeable at the widest focal length (10mm) and when used wide open at the longest focal length (24mm). The aspherical element in the lens helps control lens flare and coma, which can reduce contrast. Interestingly, the choice of aperture doesn’t significantly influence the presence of chromatic aberration, except at 24mm. Additionally, recent Nikon camera bodies can automatically detect and remove most chromatic aberrations through their smart JPEG processing engines.

On the other hand, the Sigma lens displays varying levels of chromatic aberration depending on the focal length and aperture used. At wider apertures, chromatic aberration can be quite noticeable along the edges of the image but can be corrected in post-processing using chromatic aberration sliders. Coma is present in the corners of the image, especially at wider apertures, but it can be minimized by stopping down the aperture.

In conclusion, neither lens offers a significant advantage in terms of aberration control, as both display chromatic aberration and coma to some extent. However, the Nikon camera bodies with its smart JPEG processing engines can automatically detect and remove most chromatic aberrations.


The Nikon DX 10-24mm f/3.5-4.5 and Sigma 10-20mm f/3.5 both offer good sharpness, but there are some distinctions between them.

The Nikon lens exhibits excellent sharpness in the center of the frame. At maximum aperture, there may be some softness at the edges, but this improves significantly when stopped down to around f/5.6. At 15mm and 24mm, the center sharpness is maintained, but the quality towards the edges of the frame drops off noticeably.

However, stopping down enhances the edges, with peak performance being achieved between f/5.6 and f/8. The lens performs better at the telephoto range of its focal lengths, peaking at f/5.6. It is also worth noting that sharpness can vary slightly between individual shots due to manufacturing tolerances.

On the other hand, the Sigma lens produces impressively sharp images in the center of the frame, especially at its widest angle and wide open at f/3.5. Sharpness in the mid-sections improves at f/5.6, while the corners are soft at wide apertures at all focal lengths but sharpen up to acceptable levels around f/5.6-8 depending on the zoom length.

Stopping down produces marginal gains, with the sharpest aperture being around f/8. However, corner sharpness can be a concern, particularly at 10mm, where even stopping down doesn’t fully solve the issue.

In conclusion, both lenses offer good sharpness, but the Sigma lens appears to have an advantage as it provides impressive center sharpness at its widest angle and wide open at f/3.5. The Nikon lens, however, have an advantage in terms of edge-to-edge sharpness when stopped down, particularly at the telephoto end of its focal lengths.

Bokeh Quality

The Nikon DX 10-24mm f/3.5-4.5 and Sigma 10-20mm f/3.5 lenses both exhibit unique bokeh qualities, though wide-angle lenses typically do not prioritize bokeh as a primary feature.

The Nikon lens employs a 7-segment diaphragm with rounded blades for pleasing bokeh, resulting in smooth and creamy out-of-focus areas. However, with an ultrawide-to-wide zoom, having anything substantially out of focus is rare and requires conscious effort to zoom in, focus close, and use a wide aperture to achieve notable bokeh.

In comparison, the Sigma lens produces a surprisingly nice bokeh at wide apertures, though it may be challenging to achieve much background blur at 10mm unless focusing on something very close. The lens’s 7-aperture-blade design does not produce particularly appealing blur quality, with a slight ring and aperture shape visible when stopped down smaller than f/4.5.

Considering that bokeh quality is not a primary concern for wide-angle lenses, both lenses offer some degree of bokeh when used in specific shooting scenarios. However, the Nikon lens appears to deliver a smoother and creamier bokeh due to its rounded diaphragm blades. In situations where bokeh plays a role in wide-angle photography, such as environmental portraits or close-up photography, the Nikon lens would be the superior choice for achieving a more pleasing bokeh effect.


The Nikon DX 10-24mm f/3.5-4.5 and Sigma 10-20mm f/3.5 lenses exhibit different levels of flare and ghosting, which can impact image quality in specific lighting conditions.

The Nikon lens can be affected by flare when pointed towards strong light sources, such as during night photography or at sunrise/sunset. However, it is reasonably free from ghosts and exhibits only slight flare or ghosting when aimed directly at a strong light source, an impressive result for a wide-angle zoom lens. While it may not be as resistant to flare as some other lenses, it still delivers good image quality and sharpness.

On the other hand, the Sigma lens is more prone to flare, especially at night, with strong light sources causing noticeable flare. The lens hood doesn’t provide much assistance in combating this issue. When the sun is in or near the frame, a green spot or amber/orange-colored blob might be visible, though infrequent. Ghosting control is generally good, but when stopped down hard (f/11-22), ghosting becomes more noticeable. To mitigate this, it’s recommended to use your hand to block bright light sources even when the lens hood is on, particularly at the super wide end.

In conclusion, the Nikon lens offers better performance in terms of flare and ghosting control compared to the Sigma lens. Although it may exhibit some flare under certain conditions, it manages ghosting more effectively and maintains good image quality and sharpness, making it the superior choice for shooting in challenging lighting situations.


The Nikon DX 10-24mm f/3.5-4.5 and the Sigma 10-20mm f/3.5 lenses exhibit different levels of vignetting, which may impact the overall image quality.

The Nikon lens displays noticeable corner shading, or vignetting, particularly when used wide open at wider focal lengths. At 10mm, the corners can be two-thirds to three-quarters of a stop darker than the center, but this reduces to around a third of a stop by f/11. Despite the presence of vignetting, it is relatively low for a wide-angle zoom lens and can be easily corrected using lens-profile correction in software like Lightroom or Photoshop.

On the other hand, the Sigma lens vignetting varies depending on the focal length and aperture used. It can be quite noticeable, especially at wider angles and larger apertures. Stopping down the aperture or zooming in can help reduce the amount of vignetting, as can using a lens hood or shading the lens with a cap. The level of vignetting may be acceptable for some users, while others might find it distracting.

While both lenses exhibit vignetting, the Nikon lens’s performance is more consistent, and the vignetting is relatively low for a wide-angle zoom lens. However, vignetting can be easily corrected in post-processing, ensuring that your images maintain a consistent brightness across the frame.


The Nikon DX 10-24mm f/3.5-4.5 and the Sigma 10-20mm f/3.5 both exhibit distortion, though they manifest in different ways.

The Nikon lens displays noticeable barrel distortion at 10mm, a common trait for ultra wide-angle lenses. However, this distortion is dramatically reduced in JPG files thanks to in-camera correction, such as in the Nikon D7100. The distortion pattern remains consistent across the frame, making it relatively easy to correct in image editing software. At 24mm, the lens presents pincushion distortion, but it is relatively low and rarely an issue. When the aperture is stopped down, such as at f/8, distortion becomes a non-issue. Although the lens has a fair amount of distortion, it is usually invisible in most shots, except when straight lines appear along the edges.

In contrast, the Sigma lens exhibits some level of distortion, particularly noticeable in architectural or interior photography when shooting straight lines along the edges of the image. At 10mm, the distortion is present in a “flat” section in the middle at all focal lengths, making it difficult to completely correct in post-processing. Distortion is almost flat at 14mm and has been significantly reduced compared to the previous version of the lens. The lens also demonstrates some barrel distortion at 10mm and noticeable pincushion distortion at 20mm. Despite the distortion, the lens still offers great value and performance for creative purposes.

In conclusion, the Nikon lens performs better in terms of distortion control compared to the Sigma lens. The consistent distortion pattern makes the Nikon lens a more reliable choice for photographers seeking minimal distortion in their images. While both lenses exhibit some level of distortion, the Nikon lens’s performance is more consistent, and the distortion is often invisible in most shots.

Final Verdict

After taking all factors into consideration, the Nikon AF-S DX NIKKOR 10-24mm F3.5-4.5G ED has more advantages overall. It offers better portability, weather sealing, usability, flare and ghosting control, distortion control, and more pleasing bokeh. However, the Sigma 10-20mm F3.5 EX DC HSM does have its merits, such as better low light performance, image quality consistency, and center sharpness.

Considering the significant price difference between the two lenses, it’s important to weigh your priorities and budget. If you can afford the higher price and value the advantages offered by the Nikon lens, it would be the recommended choice. However, if you are on a tighter budget and can work around the drawbacks of the Sigma lens, it still offers great value and performance for its price.
