The Sigma 150mm F2.8 EX DG Macro HSM is a versatile and high-quality macro lens designed for Canon EF mounts. It's well-regarded among photographers who specialize in capturing close-up images of subjects ranging from flowers to insects. With a focal length of 150mm, this lens provides a comfortable working distance, allowing you to capture fine details without disturbing your subject.
One of the standout features of the Sigma 150mm F2.8 is its fast maximum aperture of f/2.8. This allows for excellent depth of field control and the ability to work in lower light conditions. The bokeh produced by this lens is pleasing, making it a great choice for isolating subjects against blurred backgrounds. The lens also boasts a 1:1 magnification ratio, essential for true macro photography, enabling you to explore intricate details in your subjects.
Another advantage of the Sigma 150mm macro is its construction. It features a robust build quality and weather-sealed design, providing durability and reliability in various shooting environments, which is crucial for outdoor macro work. The Hyper Sonic Motor (HSM) ensures fast and quiet autofocus, allowing you to capture decisive moments without being intrusive.
However, it's important to consider some drawbacks. The lens can be quite heavy, weighing in at around 800 grams (1.76 lbs), making it less suitable for extended handheld use without a tripod or stabilizer. Additionally, while the autofocus is generally reliable, some users have reported that in low-light conditions, it can struggle to lock focus quickly.
Overall, the Sigma 150mm F2.8 EX DG Macro HSM is an exceptional lens for macro photography enthusiasts using Canon mounts. Its combination of impressive optical performance, solid build quality, and useful features makes it a top contender in the macro category. However, potential buyers should weigh its weight against their specific needs, especially if they plan to use it for extended periods without support.
