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

The RF 28-70mm f/2.8 IS STM covers wide to short telephoto at a constant f/2.8
in a body noticeably smaller and less expensive than the RF 24-70mm f/2.8 L.
Starting at 28mm rather than 24mm is the trade you make for that, and the barrel
collapses for transport. For everyday shooting — landscapes through portraits —
it works as a single-lens kit.

Optics

• Two ultra-low dispersion elements correct chromatic aberration and lighten the front group.
• Two glass-molded aspherical elements control aberrations while keeping the barrel short.
• Super Spectra Coating holds contrast in strong backlight.

Autofocus and stabilization

• STM stepper motor — fast and quiet for both stills and video.
• Optical Image Stabilizer — up to 5.5 stops, or up to 7.5 stops with a compatible in-body system.
• Controlled focus breathing — framing holds steady through focus pulls.

Build

• Collapsible design for portability.
• Customizable Control Ring plus a separate manual focus ring.
• Weather-sealed against dust and moisture.
