Canon RF-S10-18mm f/4.5-6.3 IS STM ultra-wide-angle zoom lens launched – Times of India

Canon has launched the RF-S10-18mm f/4.5-6.3 IS STM, a new ultra-wide-angle zoom lens designed for APS-C EOS R cameras. Compact and lightweight to match APS-C camera bodies, it has a smaller footprint compared to its EF-S and EF-M counterparts. Its 16mm to 29mm full-frame equivalent focal range offers ultra-wide coverage ideal for travelogs, selfies, and shooting in tight spaces.
The company claims that the RF-S10-18mm f/4.5-6.3 IS STM delivers sharper, steadier images even in low light condition. With built-in Optical Image Stabilizer (Optical IS), camera shake can be reduced by up to 4 shutter speed stops’ equivalent, so images are less likely to be blurry even when the shutter speed slows.
One can turn off the AF at the 10mm mark to shoot even closer (closest focusing distance: 0.086m) and achieve half-macro (0.5x max. magnification) shots with the unique Centre Focus Macro effect.
Despite its lightweight body, the RF-S10-18mm f/4.5-6.3 IS STM delivers image quality that surpasses its bigger EF-S counterpart. The RF mount’s short back focus enables a lens configuration that optimises image quality while minimising the number of elements, keeping ghosting, chromatic aberration, and colour blurring well under control. Ornate details are rendered in crisp quality all the way to the edges.
