Review

The Sigma 105mm F2.8 EX DG Macro is a solid choice for photographers looking to delve into the world of macro photography without breaking the bank. This lens is designed for Canon EF mounts, making it an excellent addition for Canon DSLR users who appreciate both detail and versatility.

Build Quality and Design

One of the first things to note is the build quality of the Sigma 105mm F2.8. It features a robust design that feels sturdy in hand, thanks to its all-metal body. This durability ensures that it can withstand the rigors of outdoor shooting, which is particularly beneficial for macro photography, where you're often in less-than-ideal conditions. The lens also feels balanced when mounted on a Canon camera body, allowing for a comfortable shooting experience, even during extended sessions.

Optical Performance

In terms of optical performance, the Sigma 105mm Macro lens excels. With a maximum aperture of F2.8, it provides the ability to shoot in lower light situations effectively while producing a beautiful bokeh for portraiture. The sharpness of this lens is outstanding and remains consistent throughout the aperture range, making it a favorite for both macro and portrait photography. The lens also incorporates several special lens elements to minimize aberrations and distortion, ensuring that images are not only sharp but also true to life.

Autofocus System

While the lens features a fast and accurate autofocus system, some users have reported that the autofocus can be a bit slow or inaccurate in very close-up situations. This is not uncommon in macro lenses due to the shallow depth of field, and some seasoned macro photographers may prefer to switch to manual focus to ensure precision. Nonetheless, when the autofocus does lock on, it is generally reliable, and the lens produces crisp and clear images.

Usability

The lens has a 1:1 magnification ratio, allowing you to capture stunning detail at close range. The working distance of 14.5 cm makes it easy to photograph small subjects while keeping a respectful distance. The focus ring is smooth and well-damped, making manual adjustments simple and accurate. Also, the lens features a focus limiter switch, which can save time while shooting by preventing the lens from searching through its entire focus range.
