Review

The Canon RF 10-20mm F4 L IS STM is a versatile ultra-wide-angle zoom lens designed for Canon’s RF mount mirrorless cameras. This lens offers a unique perspective that caters to landscape photographers, architecture enthusiasts, and vloggers alike, thanks to its wide focal length range.

One of the standout features of this lens is its constant F4 aperture throughout the zoom range. This aperture allows for consistent exposure settings, making it easier to achieve the desired creative look, especially in changing light conditions. The lens also boasts Canon's renowned image stabilization (IS), which is particularly valuable when shooting handheld at slower shutter speeds, reducing the risk of motion blur.

The build quality of the RF 10-20mm is impressive, as expected from a Canon L-series lens. It feels robust in hand with a weather-sealed design, ensuring that it can withstand various shooting environments. The lens is compact and lightweight, making it an excellent choice for travel and on-the-go shooting without compromising image quality.

The optics of this lens are equally noteworthy. It employs advanced lens elements and coatings that help to minimize chromatic aberration and ghosting, delivering sharp and contrast-rich images. The ultra-wide angle is perfect for capturing expansive landscapes or crowded indoor settings, allowing for creativity in composition.

However, there are some downsides to consider. While the F4 aperture is adequate for most situations, it may not be ideal for low-light conditions when compared to wider aperture lenses. Additionally, the lens's wide perspective can introduce distortion at the edges, especially when capturing straight lines, which might require post-processing adjustments for architectural images.
