Sigma APO Macro 180mm F2.8 EX DG OS HSM

Nikon F (DX/FX)

Review

The Sigma APO Macro 180mm F2.8 EX DG OS HSM is a lens that stands out in the macro photography landscape, particularly for Nikon F (DX) mount users. With its impressive focal length and wide aperture, this lens opens up a myriad of creative opportunities for both amateur and professional photographers alike.

Build Quality and Design

The first impression of the Sigma APO Macro 180mm is its robust construction. It features a solid metal barrel that instills confidence in its durability. The lens feels substantial in hand, balancing well on Nikon DSLRs, which is a crucial aspect for longer focal lengths. The finish is sleek, and the attention to detail in design is evident. Sigma's EX series is known for quality, and this lens does not disappoint.

Optical Performance

When it comes to optical performance, the Sigma 180mm macro excels in sharpness, especially at the center. Even wide open at f/2.8, the images are impressively sharp, with only a slight drop in sharpness at the corners. This lens stands out for macro work, where details matter. Moreover, it provides excellent color rendition and contrast, producing vibrant and true-to-life images.

The lens also features Sigma’s Optical Stabilization (OS), which is particularly useful when shooting at slower shutter speeds, allowing for clearer handheld shots. However, be aware that while the stabilization helps in reducing camera shake, it is primarily intended for general use and may not be perfect for the most critical macro applications.

Autofocus and Usability

The autofocus system is generally reliable, with a decent speed and accuracy for most scenarios. For macro photography, however, manual focusing often yields better results, especially when working with very shallow depth of field. The focus ring is smooth and offers good resistance, which is beneficial for fine adjustments.

Compatibility with the Nikon F (DX) mount ensures that this lens can be used on a wide range of Nikon bodies, which is a big plus. However, users should note that due to the longer focal length, the effective angle of view on DX cameras is equivalent to a 270mm lens, making it important to have sufficient working distance when photographing small subjects.

Pros and Cons

Pros

• Excellent build quality and durability.
• Sharp images at both f/2.8 and stopped down.
• Great color rendition and contrast.
• Effective Optical Stabilization (OS).
• Versatile for macro and portrait photography due to 180mm focal length.

Cons

• Autofocus may not be swift enough for fast-moving subjects.
• Bulkier compared to similar macro lenses.
• Working distance can be challenging for extremely small subjects.

Verdict

In conclusion, the Sigma APO Macro 180mm F2.8 EX DG OS HSM is a formidable choice for Nikon F (DX) mount users looking for a specialized macro lens. With its robust build, sharp optics, and useful stabilization features, it is a lens that can help elevate your macro photography to new heights. While it may have some drawbacks, particularly in autofocus speed and size, the benefits it offers far outweigh these concerns, making it a worthy investment for serious macro photographers.
