Review

The Sigma 135mm F1.8 DG HSM Art lens for Nikon F (DX) mount is a superb offering that combines premium optical performance with a sturdy build, making it an enticing choice for photographers focused on portrait and event photography. This fast prime lens is equipped with a large maximum aperture of f/1.8, which is valuable for producing stunning bokeh while also allowing for excellent low-light performance.

Design and Build Quality

One of the first things that strikes you about the Sigma 135mm Art lens is its well-built design. The lens has a robust construction featuring a combination of thermally stable composite material and metal, giving it a solid, high-quality feel. The smooth focus ring is a delight to use, allowing for precise adjustments that are essential for critical focus. Additionally, the lens is weather sealed, which adds a layer of protection for shooting in varied conditions.

Optical Performance

When it comes to image quality, the Sigma 135mm F1.8 does not disappoint. The lens offers exceptional sharpness, even wide open at f/1.8, making it a fantastic choice for portrait photography where detail is crucial. Chromatic aberration is extremely well-controlled, as is distortion, which means your images are likely to come out clean and true to life. The bokeh produced by the nine-rounded blades delivers a soft and pleasing background that helps your subject stand out beautifully.

Autofocus System

The Hyper Sonic Motor (HSM) used in the Sigma 135mm Art lens provides fast and accurate autofocus, which is particularly useful for dynamic subjects or events where timing is everything. On the Nikon F (DX) body, autofocus performance remains responsive, although in low-light conditions, there may be some hesitation compared to other lenses. Manual focus is also smooth and precise, making it easy to fine-tune your shots.

Compatibility and Use

Although designed for full-frame sensors, this lens can also be utilized on Nikon DX crop sensors, where it translates to an effective focal length of approximately 202.5mm. This characteristic can be ideal for portrait photographers looking to frame their subjects tightly without the need to move closer. However, it may feel limiting to those who prefer a wider focal range for more versatile shooting options.
