OM SYSTEM Olympus M.Zuiko Digital ED vs Sigma 17-

Overview of the Products

When comparing the OM SYSTEM Olympus M.Zuiko Digital ED 60mm F2.8 Macro and the Sigma 17-40mm F1.8 DC, it’s clear that each lens serves distinct purposes tailored to different photography needs. The Olympus lens is priced at $549.99, while the Sigma lens is more expensive at $919.00, representing a difference of about 67%. Understanding their features will help you decide which lens is best for your photography style.

Lens Type and Purpose

The OM SYSTEM Olympus M.Zuiko Digital ED 60mm F2.8 Macro is specifically designed for macro photography, allowing for a life-size 1:1 magnification with a minimum focusing distance of approximately 7.4 inches. This makes it an excellent choice for capturing fine details in subjects like insects or flowers. On the other hand, the Sigma 17-40mm F1.8 DC serves as a versatile zoom lens, ideal for a range of photography from portraits to landscapes. Its wide focal length range offers flexibility, but it does not specialize in macro capabilities like the Olympus lens.

Aperture and Low-Light Performance

The Sigma lens features a bright F1.8 constant aperture, which excels in low-light situations and provides creative depth effects. This is particularly beneficial for portrait photography and videography. In contrast, the Olympus lens has a maximum aperture of F2.8, which, while still respectable, doesn’t provide the same level of low-light performance as the Sigma. If low-light photography or achieving shallow depth of field is a priority, the Sigma lens takes the lead in this category.

Build Quality and Design

Both lenses exhibit high build quality, but they cater to different environmental needs. The Olympus M.Zuiko lens boasts a weather-sealed design, offering protection against dust and moisture, making it suitable for outdoor macro photography in various conditions. The Sigma lens, while well-made, doesn’t highlight any weather-sealing features, which might be a disadvantage for photographers who routinely shoot in challenging environments. Thus, the Olympus lens is a better option for those who need durability and robustness.

Autofocus and Focusing Mechanism

Autofocus capabilities vary significantly between the two lenses. The OM SYSTEM lens utilizes a High-Speed Imager AF (MSC) system, designed to ensure swift and accurate focusing, especially at close distances, which is crucial for macro photography. Additionally, it includes a focus limit switch that can expedite the autofocus process. The Sigma lens, although it likely has good autofocus performance, does not specify any advanced focusing mechanisms. For macro work where precision is key, the Olympus lens has an advantage.

Image Quality and Optical Performance

In terms of optical performance, the Olympus lens features 13 elements in 10 groups, alongside ZERO (Zuiko Extra-low Reflection Optical) coating that helps reduce chromatic aberrations, ensuring high-quality image reproduction. The Sigma lens, categorized as an Art-series optic, is known for its sharp detail and professional image quality, although specific optical specifications are not provided. Both lenses promise excellent image quality, but the Olympus lens offers technical features aimed at minimizing optical flaws, making it a strong contender for those focused on detail.

Price Comparison

The price difference between these two lenses is significant, with the Sigma lens costing $919.00 compared to the Olympus lens at $549.99. This makes the Olympus lens about 40% cheaper than the Sigma. For photographers on a budget or those who don’t require the versatility of a zoom lens, the Olympus lens provides an excellent macro option without breaking the bank. However, if your work demands the flexibility of a zoom lens, the investment in the Sigma might be justified.

Which should you buy?

Choosing between the OM SYSTEM Olympus M.Zuiko Digital ED 60mm F2.8 Macro and the Sigma 17-40mm F1.8 DC ultimately depends on your specific photography needs. If you're focused on macro photography and require a lens that performs well in detail reproduction and low-light conditions, the Olympus lens is an excellent choice, especially given its lower price point. On the other hand, if you need a versatile lens for a variety of shooting scenarios, including portrait and landscape photography, the Sigma lens may be worth the higher investment.
