The EF 1:1.8/50mm STM comes with an improved technical design compared to its predecessor: The Canon Super Spectra coating reduces ghosting, the 7-blade iris creates smooth bokeh effects, and the Canon Stepping Motor (STM) provides continuous and nearly silent autofocus. Compact, lightweight, and affordable, the EF 1:1.8/50mm STM is a welcome addition to any camera bag.
The high aperture of 1:1.8 allows for precise control of depth of field: It enables creative freedom to focus on the subject while blurring the rest of the image into a soft background. This directs the viewer's attention immediately to a specific area of the image. Furthermore, the lens, with its large maximum aperture, is ideally suited for use in low-light conditions.
With a focal length of 50mm, the lens is very well-suited for portrait photography when paired with an EOS DSLR with an APS-C sensor. Even on full-frame cameras, the EF 1:1.8/50mm STM is a practical lens for a wide range of everyday tasks, offering a natural field of view and corresponding perspective.
The lens features a minimum focusing distance of just 35 cm, allowing you to get even closer to the subject and achieve a higher magnification. The 7-blade iris creates attractive light reflections in an out-of-focus background. The improved image quality of the lens compared to its predecessor is thanks to the Canon Super Spectra coating, which effectively reduces lens flare and stray light.
The lens has a compact and lightweight design, weighing only 160 grams. It fits easily into a camera bag without significantly adding to the overall weight of the equipment. The new design of the lens is compatible with both entry-level and semi-professional EOS cameras and features a metal lens mount for a robust connection to the camera body. Additionally, the lens allows for precise control of the focus plane with its manual focus ring.
