Description — Canon RF 135mm f/1.8 L IS USM
The Canon RF 135mm f/1.8 L IS USM is a 135mm full-frame prime lens designed exclusively for the Canon RF mirrorless mount. Its f/1.8 maximum aperture places it among the fastest options available in the telephoto prime category, making it well-suited for portrait work, events, and any situation where light is limited or strong background separation is desired. The lens includes optical image stabilization, which helps counteract camera shake during handheld telephoto shooting.
Weighing 935g, it is a substantial build that reflects its full-frame telephoto prime construction. An 82mm front filter thread accommodates a wide range of standard photographic filters. The lens supports both auto and manual focus operation, giving photographers the flexibility to work in whichever mode best suits their subject or shooting style.
As a prime lens with a fixed focal length, it encourages precise positioning and intentional framing — characteristics that many photographers find improve their overall technique and image quality.
