Overview

RF28-70mm F2.8 IS STM

The RF28-70mm F2.8 IS STM lens is great for both still and video content creators who may have a smaller budget but want high quality. This lens is now the smallest, lightest, RF zoom lens with extremely high image quality (equal to that of an L-series lens). For still image creators this light and compact lens weighing in at just over one pound will be a “take anywhere” kind of lens. Offering a fast f/2.8 aperture throughout the zoom range, photographers can work in low light situations or take creative control and blur the foreground and background with wide apertures not available on standard kit lenses.

Features

Compact Size and Weight for Everyday Carry

This lens accomplishes the incredible feat of being a fixed aperture zoom lens that you can actually carry around all day without wearing your arm out. One size-reduction feature is the image stabilization unit that has been completely redesigned for this lens. Additionally, the collapsible design and the smaller focus element due to the optical system make the lens lightweight and portable. Taking advantage of the benefit of electronic distortion correction, this large-aperture zoom lens with a fixed f/2.8 aperture achieves both high image quality across the entire image and a compact optical system.

High-Image Quality and Optical Design

There is a lot that contributes to the optical quality of this lens, and it starts with two Ultra-low Dispersion (UD) elements (marked as dark green). The large-diameter UD lens at the front is a unique configuration previously found only in L lenses. This configuration effectively corrects chromatic aberration, reduces the weight of the front lens group, and contributes to ease of use by suppressing the change in the center of gravity felt by the user when changing the zoom range. Two glass-molded aspherical lenses (marked as light green) are effectively placed to achieve high rendering performance with suppression of various aberrations and compact size. The lens provides clear, high-resolution images from the maximum aperture. This design also features dust- and weather-resistant construction (another L-series feature).
