The RF-S 55-210mm f/5.0-7.1 IS STM is a high-performance RF-S standard zoom lens engineered for Canon EOS R system mirrorless cameras. Features STM autofocus, optical image stabilization, and premium optical coatings.

The Canon RF-S 55-210mm f/5.0-7.1 IS STM stands out in the Canon RF lineup as a versatile zoom lens. At just 270 g (9.5 oz), its remarkably compact design makes it an easy addition to any camera bag.

Optically, it punches well above its weight, ensuring that your creative vision is never limited by your gear. The STM motor ensures smooth, quiet focusing adjustments, particularly beneficial during video capture. Its built-in optical image stabilization (4.5 stops standalone / 7.0 stops coordinated with IBIS) effectively mitigates camera shake, ensuring sharper handheld shots.

Specialized UD (Ultra-Low Dispersion) glass elements are employed, delivering edge-to-edge contrast and color accuracy.

It's a fantastic entry point into the RF ecosystem, offering genuine value and great image quality.
