Sigma DG 105mm f/2.8 EX OS HSM Macro

The Sigma DG 105mm f/2.8 EX OS HSM Macro is a high-quality camera glass that can focus on small objects and produce a sharp and clear image. It has a fast aperture value and 9 aperture blades that create a pleasing bokeh effect. The lens can be used with autofocus or manual focus and has a ring-type ultrasonic motor that provides quick and silent focusing. The lens is 126mm long and weighs 725 grams, making it a heavy lens that requires consideration when carrying it in a camera bag. It has a 62mm lens filter diameter, which is not commonly used, but step-up rings can be used to adapt it to other filter sizes. The lens is made with high-quality lens elements and lens coating that ensures a high resolution image. It is a well-built lens that can last for a long time.

Positives:
The Sigma DG 105mm f/2.8 EX OS HSM Macro camera lens is everything I was looking for in a macro lens. It’s incredibly solid and well-built, and it feels great in my hands. The OS (optical stabilization) feature is a game-changer for me, making it much easier to capture sharp images.

The controls on this lens are well-designed and easy to reach and use. The focus ring is smooth and precise, and it’s easy to switch between manual and autofocus. The 105mm focal length provides excellent compression and bokeh, making for beautiful macro shots.

Negatives:
One slight drawback of this lens is its weight. It’s definitely on the heavier side, which might make it a bit difficult to carry around for extended periods. However, given the build quality and optical performance, I think it’s a reasonable compromise.

Another minor issue is that the lens hood can be a bit tricky to attach and detach. This is a small complaint, but worth mentioning.

Conclusion:
Overall, I’m extremely pleased with the Sigma DG 105mm f/2.8 EX OS HSM Macro camera lens. It’s a high-end lens that delivers on all fronts, from build quality to optical performance to usability. The addition of OS is a significant advantage, and the controls are well-designed. While it may be a bit heavy, I think it’s worth the tradeoff for the image quality and overall durability. Highly recommended for macro photographers who want the best performance from their lenses.
