Canon RF 28-70mm f/2.8 IS STM Lens

Canon RF 28-70mm f/2.8 IS STM Lens

Being the first f/2.8 constant aperture non-L RF Zoom lens, the RF 28-70mm f/2.8 IS STM's new design concept emphasises a balance of size, image quality, functionality, and price, bringing a more affordable f/2.8 zoom lens option to photo amateurs and content creators.

RF 28-70mm f/2.8 IS STM features a single large diameter lightweight UD lens in the front element, new compact IS unit and a retractable lens design to help reduce the size and the weight. It weighs only 495g and 92.2mm long when retracted, achieving compact and lightweight portability.

With the RF 28-70mm f/2.8 IS STM, users can enjoy beautiful and soft bokeh at any focal length throughout the easy-to-use 28-70mm zoom range and f/2.8 constant aperture. The use of 2 UD lenses and 2 Glass-Moulded (GMo) Aspherical lenses also help suppress various aberrations to achieve high rendering performance, offering high quality images equivalent to the RF 24-105mm F4 L IS USM. Its built-in Optical Image Stabiliser offers up to 5.5-stop1 shake compensation at centre and attains up to 7.5-stop shake compensation at centre and 7.0-stop in peripheral2 when paired with EOS R-series cameras with In-Body Image Stabilisation, to facilitate low-light and hand-held shooting. RF 28-70mm f/2.8 IS STM also features high level of durability and shock resistance with dust-and-water-resistant design equivalent to that of L-series lenses, giving peace of mind to users when shooting outdoor.

Features:

An innovative compact and lightweight f/2.8 Standard Zoom lens which weighs 495 g and 92.2mm long when retracted.

The use of a single large diameter lightweight UD lens in the front element, new compact IS unit and retractable lens design help to reduce the size and the weight. The light weight of the front element also makes the centre of gravity closer to the camera, making the lens feel lighter than its actual weight.

Newly developed 15 elements in 12 groups optical design4 with the use of 2 UD lenses to correct chromatic aberration throughout the zoom range and effective placement of 2 Glass-Moulded (GMo) Aspherical lenses to achieve high rendering performance with suppression of various aberrations and compact size.

9-blade circular aperture delivers beautiful and soft background blur.

Optical Image Stabiliser offers up to 5.5-stop1 shake compensation at centre, when paired with EOS R-series cameras featuring In-Body Image Stabilisation, up to 7.5-stop shake compensation at centre and 7.0-stop in peripheral2 can be achieved through Coordinated Control IS.

0.24m (MF) and 0.27m (AF) minimum focus distance at 28mm.

0.24x max. magnification at 0.35m focusing distance at 70mm.

Equipped with Leadscrew type STM featuring a magnetic sensor that reads the motor’s rotational speed. By increasing the motor’s rotational speed and adopting feedback control, high-speed and high-precision AF has been achieved.

Supports Electronic Full Time Manual Focus5 during One-Shot or Servo AF.

Compatible with Focus Breathing Correction6 during movie shooting.

“Focus mode / Control Selector” switch design enables swift switching of “Focus / Control Ring” for manual focusing or Control Ring operation such as aperture, shutter speed, ISO speed or exposure compensation adjustment.

Renowned Super Spectra Coating and optimised shapes of lens elements help to improve anti-ghosting and flare performance.

Optional Lens Hood EW-73D further enhances flare resistance.

High level of durability and shock resistance with dust-and-water-resistant design equivalent to that of L-series lenses.
