Sony E 50mm F1 8 OSS Análisis | 54 Datos comparados

The Sony E 50mm f/1.8 OSS (SEL50F18) is a lightweight APS-C prime lens, praised for outstanding sharpness and contrast even at f/1.8, alongside smooth bokeh from a 7-blade diaphragm. Key advantages include built-in Optical SteadyShot (OSS) for handheld shooting and an internal focusing system with a 49mm filter thread. Conversely, the lens lacks full-frame coverage, forcing a cropped image on, and it features an electronic, non-tactile focus-by-wire ring. Additionally, it lacks weather sealing and produces soft sunstars rather than defined, sharp points of light.

The Sony E 50mm F1.8 OSS is a compact and affordable short telephoto prime lens designed specifically for Sony's APS-C mirrorless cameras, offering a 75mm full-frame equivalent field of view that is highly ideal for portrait photography. Tested on a 24MP sensor, the lens delivers impressive, crisp optical performance with central sharpness that peaks at f/5.6 and f/8, alongside virtually non-existent distortion. A major benefit for handheld shooters and videographers is its built-in optical image stabilization (OSS), which helps capture sharp images in challenging light. Structurally, the lens features a lightweight 7.1-ounce aluminum barrel available in silver or black, and includes a reversible lens hood. However, the lens does come with some notable design and optical compromises. Its widest apertures (f/1.8 and f/2) suffer from dim corners due to significant natural vignetting, though this can be corrected in-camera or via editing software. In terms of build and handling, it lacks weather sealing and utilizes an electronic "wire-by-wire" manual focus ring. This focus ring spins freely without hard stops or tactile feedback, making precise manual adjustments difficult to gauge. Additionally, while...

The Sony E 50mm f/1.8 OSS is an affordable APS-C prime lens tested on the Sony Nex-5n, offering an effective 75mm focal length that makes it an excellent, high-value choice for portrait and low-light photography. Priced around $300, it features a fast f/1.8 aperture, built-in Optical SteadyShot (OSS) stabilization providing a 4-stop advantage, and a durable metal exterior with an engraved focus ring. Its autofocus system relies on an internal linear and stepping motor, delivering exceptionally smooth, quiet transitions that are highly beneficial for video capture. The lens delivers sharp image performance across the frame from corner to corner and produces a creamy, pleasing background bokeh. The review highlights several pros and cons regarding its optical performance and build quality. On the positive side, its value for money is exceptionally high, the optical stabilization works effectively, and the build feels rigid and strong yet lightweight. Additionally, it features Direct Manual Focus (DMF) for seamless adjustments, and it includes a well-designed, large lens hood that screws securely into the front to prevent flare. However, the lens is not without flaws. Notable...

The review by Klaus Schroiff on OpticalLimits (formerly PhotoZone) highlights the Sony E 50mm f/1.8 OSS (SEL-50F18) as a very attractive and specialized short-telephoto prime lens for APS-C format cameras, translating to a 75mm full-frame equivalent focal length. A major pro of this lens is its excellent build quality, featuring a robust metal lens body and focus ring alongside a non-rotating front element that maintains a constant physical length during operation. Furthermore, it stands out for incorporating Sony's Optical Steady Shot (OSS), making it the fastest stabilized system lens available at the time of its release. Performance-wise, the contrast-detection autofocus is basically noiseless, supports Direct Manual Focusing (DMF), and delivers highly smooth, "buttery" bokeh highlights in both the background and foreground. Conversely, the review identifies a few clear cons regarding its real-world performance. While the addition of optical stabilization is a massive benefit for low-light photography, field testing revealed that the OSS only provides a potential of about 2 to 3 f-stops of stabilization, which was noted as being a little less than originally expected. Additionally, manual focusing operates entirely...

The Sony E 50mm F1.8 OSS is described by PCMag as an affordable, compact, and sharp portrait prime lens for APS-C cameras, featuring built-in Optical SteadyShot for stable, handheld, and low-light shooting. It offers excellent center sharpness, beautiful bokeh, and strong performance for portrait enthusiasts. Key disadvantages noted include noticeable edge softness and vignetting when shooting wide open at f/1.8, along with a lack of weather sealing. Additionally, the electronic focus-by-wire system provides limited tactile feedback, and the 75mm equivalent field of view may feel restrictive for general-purpose photography.

The Sony E 50mm f/1.8 OSS is a lightweight, metal-bodied "nifty-fifty" designed for APS-C cameras like the a6300, where it functions as a 75mm equivalent portrait lens. The review highlights excellent center sharpness and contrast even at f/1.8, with image quality becoming "excellent across the frame" by f/5.6. Key advantages include its highly effective Optical Steady Shot (OSS), which allows for handheld shooting at speeds as low as 1/30s, and a smooth "focus-by-wire" mechanism that supports accurate, albeit occasionally slow, autofocus tracking. Additionally, the lens exhibits almost no perceptible distortion and has a capable minimum focus distance of 1.28 feet for close-up shots. Despite its strengths, the lens struggles with specific optical flaws, most notably poor flare control when bright light sources are positioned just outside the frame and significant ghosting at narrow apertures like f/11. While the bokeh is "lovely" and smooth at f/1.8, it quickly takes on a distracting heptagonal shape when stopped down to f/4.0 due to the 7-bladed aperture design. Chromatic aberration is another weakness, with visible blue fringing in high-contrast areas at fast apertures that...

The Imaging Resource test reveals that the Sony E 50mm f/1.8 OSS provides a practical real-world advantage of approximately 2.5 stops, enabling sharp handheld images at 1/15s compared to a 1/60s baseline, despite a 4-stop manufacturer claim. The Optical SteadyShot (OSS) system proves highly effective for low-light photography and video by enabling slower shutter speeds without raising ISO, though performance tends to cap at 1/15s rather than achieving the advertised 4-stop correction.
