The Versatile Everyday Lens
Combining a fast aperture, compact dimensions, and a wide-to-short telephoto zoom range, the Canon RF 28-70mm f/2.8 IS USM Lens is an ideal all-in-one solution for a variety of content creators. With its 28-70mm zoom range and fast f/2.8 aperture, this lens excels at everything from sweeping landscapes to intimate portraits and more. It offers L-series quality optics in a more compact and affordable package.
Compact and Fast
Compared to its L-series sibling, the RF 24-70mm f/2.8 L, the RF 28-70mm is notably smaller and lighter. This is achieved through an innovative optical design and a slightly more modest 28mm wide-angle start. When not in use, the lens collapses to save even more space in your bag or when carried over your shoulder.
The fast f/2.8 aperture provides significant advantages over other lenses with a standard f/4 aperture, such as better control over depth of field for stunning portraits and improved performance in low-light conditions. The lens’s wide aperture also delivers beautiful bokeh and excels at gathering light.
L-Series Optical Performance
Canon has infused the RF 28-70mm with optical performance on par with their renowned L-series lenses. This accomplishment is impressive given the lens's compact size. Its advanced optical design ensures high-resolution images across the zoom range, even when shooting wide open.
- Two Ultra-low Dispersion (UD) Elements: Located at the front, these elements correct chromatic aberration and lighten the front lens group, a feature previously exclusive to L-series lenses.
- Two Glass-molded Aspherical Elements: These reduce aberrations while helping to keep the lens compact.
- Super Spectra Coating (SSC): Minimizes backlight flaring and ghosting, maintaining light transmission and high contrast.
The RF 28-70mm also features a fast and silent stepper (STM) autofocus system and an Optical Image Stabilizer to ensure sharp imagery. The autofocus system locks onto subjects efficiently, while the stabilization helps to reduce blur from camera shake.
- Stepper (STM) Autofocus Motor: Quick and quiet, perfect for both stills and video.
- Controlled Focus Breathing: Provides smooth transitions during video recording.
- Optical Image Stabilizer: Offers up to 5.5 stops of stabilization on its own, or up to 7.5 stops when combined with a compatible camera’s in-body stabilization, minimizing blur from camera movement even in low light and at slower shutter speeds.
Lightweight and Durable Design
The RF 28-70mm’s compact, lightweight, and robust construction contributes significantly to its success. The weather-sealed build, similar to that of L-series lenses, ensures reliability in various weather conditions.
- Collapsible Design: Reduces the lens's size when not in use.
- Customizable Control Ring and Smooth Manual Focus Ring: Enhance the tactile experience of using the lens.
- Weather-Sealed Construction: Allows operation in challenging weather conditions, making it a dependable choice for photographers and videographers alike.
