What is Canon EF 28-135mm f/3.5-5.6 IS USM?
The Canon EF 28-135mm f/3.5-5.6 IS USM is a versatile zoom lens designed for Canon EOS cameras. It is commonly referred to as a standard zoom lens due to its range of focal lengths, which makes it suitable for a wide variety of photography genres, including portrait, landscape, and street photography.
The “28-135mm” designation refers to the lens’s focal length range. At the wide end, it offers a 28mm focal length, suitable for capturing expansive landscapes or group shots. At the telephoto end, it provides a 135mm focal length, allowing you to zoom in closer to your subject. This flexibility makes it ideal for capturing both wide-angle scenes and close-up details without the need to switch lenses.
The aperture range of f/3.5-5.6 means that the lens can achieve a wide aperture of f/3.5 at the 28mm focal length but narrows to f/5.6 when zoomed in to 135mm. A wider aperture allows for more light to reach the camera’s sensor, enabling better low-light performance and the ability to create a shallow depth of field, which can result in attractive background blur, also known as bokeh.
The “IS” in the lens’s name stands for Image Stabilization, a technology developed by Canon to minimize the effects of camera shake. This feature is particularly useful when shooting handheld or in low-light conditions, as it helps to produce sharper images by compensating for small movements. The USM (Ultrasonic Motor) designation indicates that this lens has a fast and quiet autofocus system, ensuring quick and accurate focusing.
In conclusion, the Canon EF 28-135mm f/3.5-5.6 IS USM is a versatile lens that provides a flexible range of focal lengths, allowing photographers to capture a wide variety of scenes. With its image stabilization and fast autofocus capabilities, it is a reliable choice for both amateurs and professionals looking to expand their photographic capabilities.
