Sigma 50mm F2 8 EX DG Macro Análisis | 54 Datos comparados

The Sigma 50mm f/2.8 EX DG Macro is a versatile standard lens designed for digital SLRs that functions as a true macro lens capable of a 1:1 reproduction ratio. It features an advanced optical design with a floating focusing system for precise imaging across the entire focus range, special coatings to reduce ghosting and reflections, and an included screw-in hood. On full-frame camera bodies, the lens performs exceptionally well by delivering excellent corner-to-corner sharpness even when shot wide open, alongside very low chromatic aberration across the board. Additionally, it provides an impressive minimum aperture of f/45 or f/32 depending on the camera mount, which offers photographers an expanded depth of field. Despite its strong optical performance, the review highlights a few notable drawbacks, particularly when the lens is paired with a full-frame sensor. Light falloff (vignetting) in the corners increases on full-frame bodies, hitting a maximum of 0.7 EV at f/2.8; unusually, this shading never drops below 0.22 EV even when the lens is significantly stopped down. Distortion also changes on full-frame cameras, shifting from negligible barrel distortion to a...

The Sigma 50mm f/2.8 DG Macro EX is a well-built, high-performance prime lens offering excellent optical quality at a reasonable price point, according to ePHOTOzine. It is versatile for macro work and functions well as a portrait lens on cropped sensors, boasting a robust finish and a functional, included metal hood. ePHOTOzine Key drawbacks identified include a short working distance at 1:1 magnification due to an extending front element and a slow autofocus system, which can impact shooting efficiency. Additionally, unlike other lenses in the EX series, this model lacks an included soft storage case. ePHOTOzine

The Sigma 50mm f/2.8 EX DG lens is characterized by ePHOTOzine as a budget-friendly, highly capable macro option featuring outstanding center sharpness when stopped down and a solid build with a versatile metal hood. It offers good value for close-up work and, on APS-C sensors, functions well as a portrait lens. Conversely, the review notes the lens suffers from slow, noisy autofocus and an extending front element that mandates very short working distances for 1:1 macro, highlighting a lack of modern features like stabilization. It is deemed a worthy alternative for those seeking macro capabilities without a high price tag, despite these functional compromises.

The Shutter Journey Singapore review highlights the Sigma 50mm F2.8 EX DG Macro as a highly versatile and budget-friendly "convenience lens". Tested on an APS-C Pentax K-X camera (giving a 75mm equivalent focal length), the reviewer emphasizes its ability to handle multiple genres beyond traditional macro work, making it an excellent choice for portraits, structured buildings, and landscapes. A standout design feature is its uniquely flat front element, which renders near-zero distortion and makes it perfect for photographing flat objects like paintings and stamps. Despite packed optics consisting of 10 elements in 9 groups, the lens maintains a highly portable, lightweight footprint of just 320 grams. shutter journey singapore Pros and Cons Breakdown Pros: The lens delivers exceptional, tack-sharp image quality and achieves a true life-size (1:1 magnification) macro ratio for capturing intricate details of insects and flowers. It features a flat front optic that effectively eliminates distortion, an extensive aperture range that stops down all the way to f/32 for advanced depth-of-field control, and a humble, affordable price point. shutter journey singapore Cons: The review notes that this is...

The Sigma 50mm f/2.8 EX DG Macro is a highly budget-friendly "sleeper" lens that offers true 1:1 macro magnification for a fraction of the cost of modern mirrorless equivalents. Its standout pros include exceptional center sharpness, excellent image contrast, smooth bokeh, and a dense, high-quality "EX" build. Additionally, the "DG" digital-grade coating effectively minimizes ghosting and flare. It features a useful focus limiter switch to stop the lens from hunting during standard portrait or street photography, making the 50mm focal length highly versatile for everyday walkaround use. However, the lens comes with notable ergonomic and mechanical cons. It relies on a telescoping barrel design that doubles in length at maximum magnification, reducing the working distance to just two inches and making it easy to shadow subjects or scare away insects. Furthermore, it lacks an internal autofocus motor, meaning it will only autofocus on Nikon DSLRs with built-in screwdriver motors; it is strictly manual-focus on entry-level DSLRs and modern Nikon Z mirrorless cameras using the FTZ adapter. The autofocus performance itself is noisy and slow, the older matte crinkle finish can...
