Canon EF50MM F/1.8 STM Lens for Canon DSLR Cameras

El objetivo Canon EF 50mm f/1.8 STM es una excelente opción para fotógrafos que buscan una lente con una apertura amplia y una distancia focal estándar. La calidad de imagen es excelente, con colores nítidos y vibrantes y una gran capacidad de capturar detalles. Además, el motor de enfoque silencioso y rápido lo hace ideal para fotografía en movimiento y video.

Una de las principales ventajas de este objetivo es su relación calidad-precio. Por su precio, es difícil encontrar otro objetivo que ofrezca una calidad de imagen tan buena. También es muy ligero y compacto, lo que lo hace fácil de llevar y manejar.

Sin embargo, el enfoque automático puede ser un poco lento en situaciones de poca luz, y la construcción del objetivo es bastante básica. Aunque esto no afecta a la calidad de imagen, puede hacer que el objetivo se sienta un poco menos resistente.

En general, recomendaría este objetivo a fotógrafos que buscan una lente con una apertura amplia y una distancia focal estándar para retratos, paisajes y fotografía de calle. Es perfecto para aquellos que quieren experimentar con la fotografía con poca luz o crear un efecto bokeh impresionante.

En resumen, el objetivo Canon EF 50mm f/1.8 STM es ideal para capturar retratos con un efecto bokeh impresionante, paisajes con gran nitidez y profundidad y fotografía de calle con una perspectiva natural. También es excelente para capturar detalles en objetos cercanos y crear imágenes con un aspecto artístico y desenfocado en el fondo.

The Canon EF 50mm ƒ/1.8 STM is the third lens in the 50mm line for Canon, the original having been released in 1987 and updated in version II in 1990. Twenty-five years later, the lens has been overhauled with the new STM focusing system and a new look, but otherwise the optical design is unchanged.

The lens was designed to fit the EF (35mm) mount, and will also work on the EF-S mount for 1.6x cropped sensor bodies, as well as Canon’s existing APS-H (1.3x crop) bodies. On these bodies the equivalent field of view is 80mm and 65mm respectively.

The lens is available now for approximately 8k

Sharpness
Used wide open at ƒ/1.8 or ƒ/2, the lens exhibits substantial corner softness. On a sub-frame camera like the 7D it’s not quite as noticeable as on a full-frame camera like the 1Ds mkIII, because the sensor doesn’t capture the entire field of view offered by the lens. Either way, at ƒ/1.8 there’s only a small area of sharpness in the center of the frame, which quickly gives way to softness going out towards the corners.

Stopping down to ƒ/2.8 improves sharpness dramatically: on the sub-frame 7D, images produced are almost tack-sharp corner to corner, with a light amount of softness in the extreme corners; however, on the full-frame 1Ds mkIII there is still some corner softness to contend with. It’s not until ƒ/4 that we see true corner-to-corner sharpness, which improves negligibly as the lens is stopped down to ƒ/8.

Diffraction limiting sets in at ƒ/11, but you won’t see any practical impact on sharpness until ƒ/16 and ƒ/22.

Chromatic Aberration
The Canon EF 50mm ƒ/1.8 STM is very resistant to chromatic aberration: there is a slight amount present when the lens is used at its widest apertures, but as it is stopped down it is less prominent.

Shading (”Vignetting”)
With the Canon EF 50mm ƒ/1.8 STM mounted on the sub-frame 7D, there is a slight amount (1/3EV) of corner shading that disappears as the lens is stopped down past ƒ/2.

When mounted on the full-frame 1Ds mkIII, the lens produces some impressive corner shading when used at ƒ/1.8 or ƒ/2 – the extreme corners are one and a quarter stops darker than the center. Stopped down to ƒ/2.8, this corner shading becomes just a half-stop differential, and at ƒ/4 and smaller, corner shading becomes negligible.

Distortion
The Canon EF 50mm ƒ/1.8 STM produces images with a small amount of barrel distortion, less noticeable on the 7D than on the 1Ds mkIII: on the latter camera, images show +0.5% distortion in the corners. This is easily correctable in post-processing.

Autofocus Operation
The Canon EF 50mm ƒ/1.8 STM employs an autofocus system called a “Stepping Motor”, which allows the lens to provide smooth and quiet autofocus operation — particularly beneficial during video capture. The lens took around a second to focus from infinity to close-focus. It offers full-time manual operation by just turning the focus ring after autofocusing. Attached 49mm filters will not rotate during focus operations, making life easier for polarizer users.

Macro
The lens’ minimum close-focusing distance is just over thirteen inches, and at this minimum distance it provides a magnification of 0.21x – not great for macro work, but not terrible, either.

Build Quality and Handling
At just over five ounces, the new 50mm ƒ/1.8 STM is actually slightly heavier than the 50mm ƒ/1.8 II, which weighed an ounce less. The new lens sports a satin black finish, and uses a metal mount to attach it to the camera, however it uses 49mm filter threads instead of the more common 52mm size. The lens is devoid of any ornamentation other than its identification badge – there is no distance scale or depth-of-field markings. There’s only one control switch on the lens, to enable or disable autofocus. The diaphragm is made up of seven curved aperture blades, compared to the previous version’s five, which should make for more pleasing bokeh results.

The Canon EF 50mm f/1.8 STM lens is a standout choice for photographers seeking an affordable, high-quality prime lens. Its impressive image quality, wide aperture, and compact design make it an excellent tool for portraits, street photography, and low-light conditions. While it may not cater to all specialized needs, it excels within its designated range. The “nifty fifty” remains a valuable addition to any photographer’s kit, providing outstanding performance at an accessible price point.

Pros:

Superb Image Quality: The 50mm f/1.8 STM lens delivers impressive sharpness and clarity, even when shooting wide open at f/1.8. It excels in capturing details and producing vivid, true-to-life colors, making it an excellent choice for portraits, low-light conditions, and everyday photography.

Wide Aperture: The wide maximum aperture of f/1.8 allows for exceptional low-light performance and beautiful background blur (bokeh) effects. It enables users to shoot in challenging lighting situations without sacrificing image quality.

Lightweight and Compact: Weighing just over 5 ounces, this lens is incredibly portable, making it a perfect companion for travel or casual photography. It adds minimal weight to your camera, allowing for easy handling and maneuverability.

Silent and Fast Autofocus (STM): The STM motor ensures smooth and near-silent autofocus, which is particularly beneficial for video recording or situations where quiet operation is crucial. It provides quick and accurate focus without causing any disruption.

Affordability: The 50mm f/1.8 STM offers exceptional value for its price. It’s an accessible option for photographers looking to upgrade from a kit lens or those seeking to expand their lens collection without a substantial financial commitment.

Cons:

Plastic Build: The lens is primarily constructed from plastic, which may not feel as durable as some higher-end lenses. However, this contributes to its lightweight design and doesn’t necessarily compromise its overall performance.

Lack of Image Stabilization: This lens does not feature built-in image stabilization. While the wide aperture helps in low light, users may need to employ stable shooting techniques or use a tripod for longer exposures.

Fixed Focal Length: The 50mm focal length provides a natural perspective, but it may not be ideal for all types of photography. Users looking for a zoom lens or a wider field of view might need to complement this lens with others.
