The Nikon DX 17-55mm f/2.8 features 2 rings: a focus ring and a zoom ring. The focus ring is wider than the zoom ring and is situated about halfway along the barrel, providing easy and precise control. The zoom ring, positioned closer to the camera, is thinner, which might be slightly challenging for those with larger hands.

Both rings offer a smooth, damped tactile experience and are easy to operate. The lens has a windowed distance scale but lacks a depth-of-field indicator. Overall, the Nikon 17-55mm lens has a well-designed ring layout, providing good control and ergonomic handling.

On the other hand, the Sigma 17-50mm f/2.8 also has 2 rings: a focus ring and a zoom ring. The focus ring, located towards the front of the lens, features raised rubber ribs but has a small focusing range of only 45 degrees, making manual focusing more tedious.

Additionally, the focus ring is not dampened and turns freely, which can be problematic during autofocus. The zoom ring is wider, has large raised rubber ribs, and features a zoom lock to fix the lens at 17mm. Both rings are smooth and exhibit no play. The lens has a focus distance scale printed on the manual focus ring but lacks a windowed distance scale and depth-of-field indicator.

Comparing the two lenses, the Nikon 17-55mm lens has a superior ring design due to its well-balanced layout, smooth operation, and better ergonomics. The Sigma 17-50mm lens, while still functional, has a few shortcomings in its focus ring and distance scale design that make it less ideal for precise control and adjustments.

Switches/Buttons

The Nikon DX 17-55mm f/2.8 features a single slider switch located on the left side of the barrel, which selects between M/A (autofocus with manual override) and M (manual only) focusing. This streamlined approach offers a simple and easy-to-use control for adjusting the focus mode during shooting. However, it lacks additional controls for other features.

On the other hand, the Sigma 17-50mm f/2.8 is equipped with two switches: one for image stabilization and one for autofocus/manual focus. These switches are noticeably raised from the lens barrel and are situated close to the lens mount. Their prominent design makes them easy to locate and use without causing discomfort during shooting, providing more accessible control options for various features.

Comparing the two lenses, the Sigma 17-50mm lens has a superior switches/buttons design due to the inclusion of both image stabilization and autofocus/manual focus controls. These easily accessible switches offer more functionality and convenience during shooting. The Nikon 17-55mm lens, although straightforward and user-friendly, is more limited in its control options, which might not be as suitable for photographers who desire more flexibility with their lens controls.

Filter Thread

The Nikon DX 17-55mm f/2.8 features a 77mm plastic filter thread that does not rotate when focusing, ensuring compatibility with polarizers and graduated filters. The plastic construction keeps the lens lightweight, but may be less durable than metal threads with frequent mounting and dismounting of filters.

In contrast, the Sigma 17-50mm f/2.8 also has a 77mm plastic filter thread at the front of the lens. This design holds large, vignette-free filters and offers a thread to attach the included lens hood. Like the Nikon lens, the front element of the Sigma lens does not rotate while focusing, making it easy to use with circular polarizers and ND grads.

Focusing Performance

The Nikon DX 17-55mm f/2.8 boasts fast and accurate autofocus performance, driven by Nikon’s Silent Wave Motor (SWM) technology. While its AF speed is average, autofocus accuracy is spot-on at every distance and focal length. The lens performs well in low-light situations, especially when using a focusing aid like an illuminator found on most flashguns.

The initial autofocus acquisition speed is good, and manual focus override allows for instant manual focus adjustments. With its smooth, well-damped focus ring, the Nikon 17-55mm features an internally focusing design, which means the lens length remains constant. Additionally, it does not exhibit focus breathing, making it ideal for cinematographers.

Conversely, the Sigma 17-50mm f/2.8 has decent autofocus performance, although it may not be as quiet as some users prefer. Its focusing speed is generally fast, taking about one second to focus from close to infinity. The lens performs well in low-light situations but may occasionally hunt for focus in very low light conditions. The initial autofocus acquisition speed is excellent, and the lens can focus accurately.

However, this lens lacks manual focus override, requiring a switch between autofocus and manual focus. The manual focus ring action is smooth, but its short throw makes precise adjustments more challenging. The lens features an externally focusing design, with no significant focus breathing, making it suitable for video work.

Both lenses offer good autofocus performance, but the Nikon 17-55mm has the advantage with its manual focus override, internally focusing design, and absence of focus breathing. These features make it more versatile and better suited for various photography scenarios, making the Nikon 17-55mm lens superior in terms of focusing performance.

Optical Stabilization

The Nikon DX 17-55mm f/2.8 does not feature optical stabilization, while the Sigma 17-50mm f/2.8 comes equipped with Sigma’s optical stabilization, rated at 4 stops of effectiveness. The stabilization offers excellent performance with silent, speedy, and precise compensation for camera movement.

Although it is slightly more effective than the Canon 17-55mm lens, it may not be as good as some of the more expensive lenses. With a single stabilization mode, the Sigma 17-50mm lens doesn’t make any noise during operation.

At 17mm, the lens delivers sharp handheld shots in low light with a net 3-stops of assistance from the optical stabilization at 1/4 sec exposures, and at 50mm, the shutter speed limit for sharp images is around 1/10 or 1/8 with a net 3-stops of assistance from optical stabilization.

Optical stabilization may not be as critical for wide-angle photography, but it can be beneficial in specific situations, such as shooting in low-light conditions handheld, at slower shutter speeds, or when recording video.

So, the Sigma 17-50mm lens is superior in terms of optical stabilization, as the Nikon 17-55mm lens does not offer this feature.

Aberration

The Nikon DX 17-55mm f/2.8 exhibits chromatic aberration throughout the zoom range, with fringing up to 1.5 pixels wide towards the edges when stopped down beyond f/16, which may become noticeable in large prints with high contrast near the edges.

Coma performance is generally not an issue, as it is difficult to detect any significant sagittal coma flare. Spherical aberration is somewhat controlled, though not outstanding, with issues related to field curvature at 17mm and slightly lower border sharpness at 24mm @ f/2.8 and at 55mm.

On the other hand, the Sigma 17-50mm f/2.8 shows chromatic aberration, particularly at the 17mm focal length, where green and purple fringing is noticeable in the corners. Stopping down to f/4 results in improved sharpness and contrast, although chromatic aberration remains visible.

At 28mm and 50mm focal lengths, chromatic aberration is better controlled, and corner sharpness improves. This lens performs well for astrophotography in terms of coma, with stars appearing sharp across much of the field of view.

However, corners may display pronounced coma, chromatic aberration, and astigmatism. Spherical aberration doesn’t seem to be a significant issue for this lens. When shooting out-of-focus spots, axial aberrations are visible as purple halos around contrast areas, resulting in a loss of resolution, particularly when the lens is wide open. Despite these aberrations, the lens delivers near-perfect performance for a low-cost zoom, thanks to the high technology glasses used in its construction.

In conclusion, the Sigma 17-50mm lens offers superior control over aberrations, particularly at 28mm and 50mm focal lengths, and delivers near-perfect performance for a low-cost zoom. While the Nikon 17-55mm lens has some advantages in terms of coma and spherical aberration control, the overall aberration performance is better in the Sigma 17-50mm lens.

Sharpness

The Nikon DX 17-55mm f/2.8 delivers sharp images with outstanding sharpness in the center and good levels towards the edges of the frame. Peak clarity across the frame is achieved between f/5.6 and f/8 for most focal lengths, while at 55mm, peak quality across the frame is realized at f/5.6.

The lens is super sharp wide open to mid-aperture, with great color and contrast, and locks into focus quickly. Sharpness performance is top-notch at all apertures and everywhere in the DX image, and only slightly less contrasty in the far corners at f/2.8. The lens is sharp on DX, and there is little diffraction softness even at f/22.

In comparison, the Sigma 17-50mm f/2.8 exhibits good center sharpness throughout the zoom range, even at its wide open aperture of f/2.8. Corner sharpness, on the other hand, is less impressive when the aperture is wide open, particularly at 17mm.

However, stopping down the aperture to f/5.6 or f/8 improves corner sharpness significantly, with the sharpest point being at 50mm and f/8, where the entire frame appears almost tack-sharp. The lens may not be perfect in terms of sharpness, but it still delivers excellent performance for its price range, especially in the center.

In conclusion, the Nikon 17-55mm lens offers superior overall sharpness performance, with outstanding center sharpness and good edge sharpness across the frame. While the Sigma 17-50mm lens provides excellent center sharpness, it falls behind the Nikon 17-55mm in terms of corner sharpness. Therefore, the Nikon 17-55mm lens is the superior choice when it comes to sharpness.

Bokeh Quality

The Nikon DX 17-55mm f/2.8 offers reasonably good bokeh quality. While it may not be the best among its competitors, it delivers satisfactory results for most situations, particularly considering the lens design and its primary purposes. The bokeh is generally smooth and more pleasing towards the telephoto end of the zoom range. However, there might be some minor issues with highlight rendition at certain focal lengths and apertures.

In contrast, the Sigma 17-50mm f/2.8 produces a mixed bag of out-of-focus quality, with the 7-blade aperture struggling to maintain a circular shape beyond f/4, resulting in heptagon highlights. The aspherical elements create strong edges on bokeh lights resembling rolled condoms at close range distances.

Additionally, at the minimum focusing distance and maximum focal length, the bokeh blends with poor chromatic aberrations, making the effect look worse. However, in some cases, the bokeh can look nice, creating a pleasing background blur, but it’s not consistently smooth and beautiful throughout.

In conclusion, the Nikon 17-55mm lens provides superior bokeh quality when compared to the Sigma 17-50mm lens. Although neither lens is primarily designed for bokeh performance, the Nikon 17-55mm offers smoother and more pleasing results in various situations, making it the better choice for bokeh quality.

Flare/Ghosting

The Nikon DX 17-55mm f/2.8 is prone to flare in most backlight situations, and there may be some visible contrast degradation and ghosting when the light source is directly in the picture. However, the supplied lens hood does an excellent job of keeping light from hitting the front element in most situations, and the use of thin glass UV filters such as the Hoya Super Pro1 series can help reduce flare and UV rays. It’s important to adjust your shooting angle and use good filters to minimize flare.

On the other hand, the Sigma 17-50mm f/2.8 demonstrates impressive flare and ghosting control. In various test scenarios, such as shooting directly into the sun or capturing images with strong backlight, the lens performs remarkably well, with minimal flare or ghosting issues.

The presence of a lens hood further aids in reducing flares and unwanted reflections. This level of performance ensures that the captured images maintain their clarity and contrast even in challenging lighting conditions.

In conclusion, the Sigma 17-50mm lens outperforms the Nikon 17-55mm lens in terms of flare and ghosting control. The Sigma lens handles challenging lighting situations more effectively, maintaining image clarity and contrast, while the Nikon lens requires extra measures such as using filters and adjusting shooting angles to minimize flare.

Vignetting

The Nikon DX 17-55mm f/2.8 exhibits well-controlled vignetting characteristics. On digital bodies, light falloff is effectively managed throughout the focal range. Some users don’t mind vignetting and may even use it creatively to enhance their shots.

The Sigma 17-50mm f/2.8 controls vignetting quite well, with only slight corner shading at wide open apertures and noticeably less in the mid focal lengths. Stopping down to f/4 reduces corner shading to about 1 stop at 17mm. However, a normal thickness circular polarizer filter can add a small amount of mechanical vignetting at 17mm even at f/11. Larger aperture primes suffer more from vignetting than this zoom. Overall, the Sigma 17-50mm lens exhibits standard vignetting for its class, but with good control.

In conclusion, both lenses perform admirably in terms of vignetting control. The Nikon 17-55mm lens manages light falloff effectively throughout the focal range, while the Sigma 17-50mm lens has good control over vignetting, especially when stopping down the aperture.

Distortion

The Nikon DX 17-55mm f/2.8 exhibits some distortion at both ends of the zoom range, with barrel distortion at 17mm and pincushion distortion at 55mm. However, the distortion pattern is uniform across the frame, which makes it relatively easy to correct using image editing software.

The distortion is also low in amount and not as obvious as in some other Nikkor designs. While distortion may not be a big issue for some photographers, it would require correction for architecture photography.

The Sigma 17-50mm f/2.8 distortion varies depending on the focal length used. At 17mm, the lens has medium levels of barrel distortion, which decreases as the focal length increases. However, at the telephoto end (50mm), there is slight pincushion distortion that drops the lines to the frame center, visible mostly on the horizon.

Distortion is typical for a wide-angle zoom lens, and the Sigma 17-50mm has minimal distortion, especially in the middle sector of the zoom range, meeting the zero-distortion point at around 24mm. The lens is well-controlled, and any distortion can be fixed with Adobe Photoshop Lightroom if it’s an issue.

In conclusion, both lenses show some level of distortion at their respective focal length extremes. The Nikon 17-55mm lens exhibits a uniform distortion pattern that is relatively easy to correct, while the Sigma 17-50mm lens has minimal distortion, especially in the middle sector of the zoom range. However, both lenses offer distortion levels that can be corrected with image editing software if necessary.
