The Canon RF 135mm f/1.8L IS USM is a high-performance prime lens designed for full-frame and APS-C cameras using the RF mount. Its wide f/1.8 maximum aperture allows you to capture images in low light and create a shallow depth of field that beautifully isolates subjects from their background. This optical system consists of 17 elements in 12 groups, utilizing nine rounded aperture blades to produce smooth, natural bokeh. To ensure sharp results even when shooting handheld, the lens features built-in image stabilization providing 5.5 stops of correction, which can increase to 8.0 stops when paired with a compatible stabilized body. The Nano USM motor enables fast and quiet autofocus, while the full-time manual focus option gives you precise control over your composition. You can get as close as 700mm to your subject with a maximum magnification of 0.26x, making it a versatile choice for portraiture and sports. Built for professional use, the lens is weather-sealed to protect against the elements and weighs 935 g. It measures 89.2 x 130.3 mm and uses 82mm filters. The package includes an ET-88B lens hood, an E-82 II cap, and an LP1319 case to keep your equipment protected during transport.
