Samyang 12mm F 2 AF RF S Análisis | 54 Datos comparados

summary of the lens review: The LK Samyang AF 12mm f/2 RF-S is a highly compact, lightweight (213g), and travel-friendly ultra-wide-angle prime lens designed for APS-C mirrorless cameras, now newly available for Canon RF-S mount alongside Sony E and Fujifilm X options. On Canon bodies, it provides a 96.8-degree viewing angle (approximately a 19.2mm full-frame equivalent focal length), which is well-suited for landscapes, architectural interiors, and vlogging. The lens updates its optical heritage with a fast, quiet linear stepping motor autofocus system and includes a physical AF/MF focus mode switch directly on the weather-sealed barrel. Its fast f/2 aperture makes it capable for astrophotography, while a short 0.2m minimum focus distance allows for close-ups with a pleasantly blurred background. The review highlights several key pros and cons regarding the lens's build and image performance. On the positive side, it delivers impressive overall image quality with very good sharpness across the frame when stopped down between f/2.8 and f/8, remarkably minimal native barrel distortion, and a robust build equipped with thorough weather-sealing. It also includes a included lens hood and a...

The Samyang AF 12mm F2 RF-S is a compact, lightweight wide-angle lens designed for Canon’s APS-C RF-mount cameras, such as the EOS R10. The reviewer praises its solid build quality, which includes a metal mount, weather sealing, and a quiet, exceptionally fast, and accurate autofocus system that excels even in low light and sports photography. In terms of optical performance, the lens provides strong sharpness across most of the frame and resolves straight lines well once simple distortion correction is applied in post-processing. It also boasts excellent durability, as the setup fully survived an accidental, high-impact collision with a wild kangaroo during field testing. However, the lens does exhibit a few optical drawbacks, particularly when shooting wide open at f/2. This includes visible vignetting, a minor drop-off in extreme corner sharpness, and noticeable coma and distortion when capturing stars. Furthermore, achieving a deep depth of field at f/2 is difficult because the lens has a full-frame equivalent focal length of roughly 19mm, making it tricky to keep both a close foreground and the night sky perfectly sharp at the same...

The Samyang AF 12mm f/2 RF-S is a lightweight, ultra-wide prime lens made for Canon's APS-C mirrorless cameras, costing $449. It is ideal for taking photos of landscapes, architecture, and stars at night because of its bright f/2 aperture and ultra-wide view. The lens weighs only 213 grams and is quite small, measuring just 57.2 millimeters long. It also features a Linear STM motor for very quiet autofocus and built-in weather sealing to keep out dust, light rain, and snow.
