Complementing the lens itself, the Canon RF 28-70mm f/2L USM Lens with UV Filter Kit from B&H bundles the standard zoom with a 95mm UV filter.
Canon RF 28-70mm f/2L USM Lens
Combining the versatility of a zoom with the speed typically reserved for a prime, the Canon RF 28-70mm f/2L USM is a wide-angle to portrait-length lens distinguished by its impressively unique f/2 constant maximum aperture. This bright design yields excellent low-light performance along with enhanced control over depth of field for isolating subject matter. Ultra-Low Dispersion glass is employed in the optical design, and greatly reduces color fringing and chromatic aberrations in order to realize high clarity and color accuracy. Complementing the advanced optical properties is Canon's proven ring-type Ultrasonic Motor, which delivers fast and quiet autofocus performance along with full-time manual focus control. Additionally, unique to RF lenses, this 28-70mm incorporates a configurable Control Ring for intuitively adjusting exposure settings, including ISO, aperture, and exposure compensation, from the lens itself.
Standard wide-angle to short-telephoto zoom lens is designed for use with full-frame Canon RF-mount mirrorless cameras.
Impressively bright f/2 maximum aperture maintains consistent illumination throughout the zoom range and suits working in low-light conditions as well as affords increased control over depth of field for working with selective focus techniques.
Ultra-Low Dispersion (UD) elements are featured in the optical design, and help to suppress color fringing and chromatic aberrations in order to achieve greater clarity and color accuracy throughout the zoom range.
A ring-type Ultrasonic Motor (USM), along with an internal focusing design, optimized focusing algorithms, and a high-speed CPU, is employed to deliver fast, precise, and quiet autofocus performance as well as full-time manual focus override.
Configurable Control Ring can be used to adjust a variety of exposure settings, including aperture, ISO, and exposure compensation.
As a member of the esteemed L-series, this lens has a weather-resistant design that protects against dust and moisture to enable its use in inclement conditions.
Rounded nine-blade diaphragm contributes to a pleasing bokeh quality.
Chiaro 95mm 98-UVATS UV Filter
The 95mm 98-UVATS UV Filter is one of Chiaro’s highest-rated protective UV filters with 98% light transmission. It’s ideal for photographers of all levels who demand high-quality glass and other essential features for excellent image fidelity and construction.
To achieve 98% light transmission, Chiaro uses highly-polished optical glass, multi-coating, and additional advanced elements that improve the filter’s light transmission. A scratch-resistant coating minimizes scratching of the glass and helps assure that water, oil, dust, and fingerprints are removed with a gentle wipe. Its hard-anodized aluminum filter ring is designed to screw on and off effortlessly, and it is thin to prevent vignetting when used with wide-angle lenses. Side knurling helps assure that you’ll have a firm grip when attaching or removing your filter.
Image quality is what matters most at Chiaro. The company has tested and combined many features and essentials to achieve superior image quality and the highest light transmission. To help take the confusion out of selecting a filter, Chiaro prominently displays the light transmission levels so that you can choose the perfect filter for your lens and photo session.
98% Light Transmission
Protecting your lens doesn't mean you have to lose optical quality. By using highly-polished optical glass and advanced coatings, Chiaro offers a 98% transmission rate, which is an excellent transmission rate for glass. And the company verifies the ratings with ISO certified lab testing.
The layers of advanced resistance coating on the filter are designed to resist moderate scratches, and allows you to easily clean your filter. Water beads up and rolls off your filter, and oil and fingerprints can come off with a gentle wipe. Dust and debris won't adhere to the filter and can be removed with a puff of air.
Polished Optical Glass
Glass that's polished to perfection is essential to achieve a high level of light transmission. The optical glass in this Chiaro filter is highly-polished for flatness that ensures excellent optical clarity.
Multi-coating enhances light transmission to the demanding level set for all Chiaro filters. It reduces unwanted internal reflections and ghosting that can compromise your images.
The filter blocks UV light and reduces the bluish cast of daylight that can affect color accuracy, especially at higher altitudes.
Hard Anodized Aluminum Construction
The process of hard anodizing toughens and strengthens the aluminum for a lightweight yet durable filter ring.
Measuring only 3.2mm, this filter is slim enough to use on wide-angle lenses without experiencing vignetting.
Top and Side Knurling
In addition to top knurling, Chiaro added side knurling that helps offer better options to grip the filter when you're attaching and removing it, or when you're stacking filters.
It takes two full turns to mount the filter on your lens. This feature will securely hold your Chiaro filter through the most demanding photo shoots.
The front threads on the filter allow you to stack filters by screwing them onto your Chiaro filter.
