The Nikon AF-S Nikkor 28-70mm f/2.8 ED-IF is a versatile zoom lens designed for Nikon F (DX) mount cameras, catering to a wide range of photographic needs from portraits to landscapes. With a constant aperture of f/2.8, this lens excels in low-light conditions while providing beautiful background blur thanks to its rounded 9-blade diaphragm.
The build quality of the 28-70mm f/2.8 stands out, featuring a sturdy, professional-grade design that is moisture-sealed, making it suitable for outdoor photography. The lens barrel is constructed from high-quality materials, ensuring durability over time. Weighing in at approximately 1.5 kg, it might be on the heavier side for some photographers, but the heft gives it a solid feel in hand.
When it comes to optical performance, the 28-70mm f/2.8 delivers impressive sharpness across the entire frame, especially at the center. The use of Extra-low Dispersion (ED) glass elements effectively reduces chromatic aberrations and enhances contrast. While it shows a slight drop in sharpness at the extremes of the zoom range, it remains highly usable for most practical applications.
Color rendition is another strong point of this lens, producing vibrant and natural-looking tones. The autofocus system is fast and accurate, aided by Nikon's Silent Wave Motor (SWM) technology, which ensures quiet focusing, ideal for wedding and event photography.
The 28-70mm focal length range is particularly useful for a variety of shooting styles. The versatility allows for everything from wide-angle shots at 28mm to tighter compositions at 70mm. However, as a zoom lens with a fixed aperture, it requires a more measured approach to composition compared to prime lenses, which can sometimes offer sharper images or more artistic bokeh.
That being said, the lens lacks a built-in image stabilization feature, which can be a downside when shooting at slower shutter speeds without a tripod. This is something to keep in mind for those who often find themselves in challenging lighting conditions.
Overall, the Nikon AF-S Nikkor 28-70mm f/2.8 ED-IF is an exceptional choice for photographers seeking a versatile and robust zoom lens for the Nikon F (DX) mount. With its rapid autofocus, remarkable optical quality, and professional build, it stands out as a reliable workhorse for a range of photography needs. However, the lack of stabilization and its weight may be a consideration for some, but if those factors align with your shooting style, this lens offers an impressive blend of performance and utility.
