The Tamron AF 28-80mm F/3.5-5.6 Aspherical is a versatile zoom lens designed for Nikon F (DX) mount cameras. Its focal length range makes it suitable for a variety of photography styles, from casual snapshots to portrait shots. With a moderate aperture range, this lens aims to provide good image quality while remaining portable and easy to handle.
The build quality of the Tamron AF 28-80mm is fairly decent for an entry-level lens. It has a plastic body that helps keep the weight down, which makes it an excellent choice for photographers on the go. Weighing around 400 grams, it can comfortably be carried for extended periods. The lens extends slightly when zooming, yet it retains a compact size, easily fitting into most camera bags.
In terms of optical performance, the Tamron AF 28-80mm offers respectable image quality, especially considering its price point. The lens incorporates aspherical elements that help minimize optical distortions and improve overall sharpness. You can expect reasonably good sharpness across the frame, especially at the shorter end of the zoom range.
However, at wider apertures, there may be a noticeable drop in sharpness towards the edges, particularly at the 80mm focal length. Chromatic aberration can also be a concern in high-contrast situations, though it may be manageable in post-processing.
The autofocus system of this Tamron lens is relatively straightforward and performs well under good lighting conditions. However, in low-light situations, the autofocus may struggle a little and might even hunt for focus. The lens features a focus ring that is smooth, allowing for easy manual adjustments when needed.
The zoom mechanism is also straightforward, and the rotation is consistent, making it easy to zoom in and out quickly. The lens doesn't come with a built-in image stabilization system, which could be a disadvantage when shooting at slower shutter speeds in low-light conditions.
The Tamron AF 28-80mm F/3.5-5.6 Aspherical is a solid option for Nikon DX users looking for a versatile and budget-friendly zoom lens. While it may not compete with more premium models in terms of optical quality, it offers enough performance for casual photographers and those just starting in the field. Its lightweight design and versatility make it a very usable lens for everyday situations, but keep in mind its limitations in low-light scenarios and at the extreme ends of its focal range. If you're looking for a reliable all-around lens without breaking the bank, this one may be a suitable option in your kit.
