Priced at $549.99, this lens offers high-quality optical performance with a bright f2.8 aperture that excels in low-light conditions. Its specialized macro capabilities allow for detailed close-up photography, featuring a minimum focusing distance of 7.4 inches and a 1:1 life-size magnification. This lens is particularly suited for photographers who prioritize macro photography, thanks to its advanced construction that includes 13 lens elements designed to minimize distortion and chromatic aberrations.
Overview of the Sigma 18-50mm F2.8 DC DN Contemporary
The Sigma 18-50mm F2.8 DC DN Contemporary lens is versatile and compact, aimed at photographers using Sony E-mount cameras. It is priced at $587.00, making it about 7% more expensive than the OM SYSTEM lens. With a constant f2.8 aperture across its focal range, this lens is suited for various photography styles, from landscapes to portraits. Its small and lightweight design enhances portability, while the optical quality is bolstered by in-camera aberration correction, making it a solid choice for those seeking convenience without sacrificing image quality.
Optical Performance
When it comes to optical performance, the OM SYSTEM lens is designed for extreme detail at close distances, boasting a maximum magnification of 1x and a minimum focusing distance that allows for intricate close-ups. Its construction features advanced glass materials that combat chromatic aberrations effectively. In contrast, the Sigma lens provides impressive optical quality across a versatile focal range of 18-50mm, making it adaptable for various shooting conditions. However, it lacks the specialized macro capabilities that the OM SYSTEM lens offers, making it less suitable for extreme close-up photography.
Build Quality and Design
The OM SYSTEM lens is built with a weather-sealed design, making it resistant to dust and moisture. This feature is essential for photographers who often shoot outdoors in varying weather conditions. The lens also includes a focus limit switch, enhancing its macro capabilities by speeding up autofocus during close-range shooting. On the other hand, the Sigma lens prioritizes compactness and lightweight design, making it easier to carry for extended periods. While it may not have the same level of weather sealing, its build quality is still robust enough for everyday use.
Focal Length Versatility
In terms of focal length, the OM SYSTEM Olympus lens has a fixed 60mm length, which is optimal for macro photography but limits its versatility for other styles. This lens is perfect for capturing intricate details, but it may not be ideal for broader landscapes or portraits. Conversely, the Sigma lens offers a flexible focal range of 18-50mm, allowing users to experiment with a variety of compositions and subjects. This range makes it a more versatile option for photographers who need a single lens for multiple scenarios.
Price Comparison
At $549.99, the OM SYSTEM lens is a solid investment for macro photography enthusiasts. The Sigma lens, priced at $587.00, is about $37 more expensive, which represents a price increase of approximately 7%. While both lenses cater to different photographic needs, the price difference may influence potential buyers, especially those who are budget-conscious. The OM SYSTEM lens may be seen as a better value for those specifically interested in macro work, while the Sigma lens’s versatility may justify its higher cost for those seeking an all-rounder.
Intended Use and Audience
The intended audience for the OM SYSTEM Olympus lens primarily includes macro photographers who require precision and detail in their work. Its specialized features cater to those who want to capture life-size images of small subjects. Meanwhile, the Sigma lens targets a broader audience, appealing to both novice and experienced photographers who value flexibility and convenience in their gear. This lens is ideal for users who need a reliable all-purpose lens for everyday shooting scenarios.
Which should you buy?
Choosing between the OM SYSTEM Olympus M.Zuiko Digital ED 60mm F2.8 Macro and the Sigma 18-50mm F2.8 DC DN Contemporary largely depends on your photography needs. If you specialize in macro photography and seek high detail in close-up shots, the OM SYSTEM lens offers superior performance and features tailored to that genre. However, if you prefer versatility and plan to shoot a variety of subjects, the Sigma lens provides more flexibility with its focal range and is more suitable for general use, despite being slightly more expensive. Ultimately, your choice should align with your specific photographic goals and style.
