Recommendation 2: Canon RF full-frame mirrorless lens 50mm
The Canon RF Full-Frame Mirrorless Lens 50mm is an RF mount lens designed specifically for Canon full-frame mirrorless cameras. It uses the latest optical technology, including high-resolution optical design and multiple aberration correction technologies to provide superior picture quality. In addition, the lens integrates five levels of stabilization, which helps reduce camera shake when shooting handheld, resulting in sharper**.
2. Comparison of image quality.
In terms of image quality, both lenses perform well, but there are some slight differences. The Canon EF 18-135mm USM lens has high sharpness and contrast at the wide-angle end (18mm) and slightly softer at the telephoto end (135mm). This is especially evident in landscape and architectural photography.
Canon RF 50mm F18 STM lenses are known for their excellent resolution and contrast, especially at the maximum aperture of f18 o'clock. This gives it a great advantage in portrait and street photography, with the ability to capture fine details and rich colors.
3. Performance characteristics.
The focal length range of the Canon EF 18-135mm USM lens makes it a very practical lens for travel and landscape photography. Its focal length covers common focal lengths from wide-angle to telephoto, allowing photographers to shoot a wide range of scenes without changing lenses. In addition, the addition of a USM motor makes this lens excellent in terms of autofocus speed and accuracy, especially for shooting dynamic scenes.
