Canon unveils a much lighter and smaller f28 zoom lens for its full-frame mirrorless cameras

Canon has recently introduced a groundbreaking standard zoom lens for its full-frame mirrorless cameras, the RF 28-70mm F2.8 IS STM.

This new lens, weighing just 17.3oz (490g), promises to be a versatile upgrade for photography enthusiasts, offering a constant f/2.8 aperture across its entire zoom range.

A Promising Addition for Photography Enthusiasts

The launch of the RF 28-70mm F2.8 IS STM represents Canon’s latest effort to meet the needs of photography enthusiasts. At only 17.3 ounces, this lens is designed to be both lightweight and compact, making it an ideal companion for Canon’s enthusiast-level cameras. The lens offers a constant f/2.8 aperture, which makes it a compelling upgrade option from Canon’s previous RF 24-50mm F4.5-6.3 IS STM kit lens.

Optical Features and Performance

One of the standout features of this new lens is its 5.5 stops of optical image stabilization. This ensures that photographers can achieve sharp and clear images even in low-light conditions. Additionally, the RF 28-70mm F2.8 IS STM includes a customizable focus/control ring. This feature allows users to change the ring’s function depending on the selected focusing mode, adding a level of versatility and customization for users.

Comparisons with Other Lenses

Moreover, Canon’s professional L-series lenses, such as the RF 24-105mm F4L IS USM, are significantly heavier and more expensive. These L-series lenses are designed for professional use, offering superior performance and durability but at the cost of portability and price.

Ideal for Enthusiasts and Semi-Professionals

The weather-resistant construction of the lens ensures that it can withstand challenging shooting conditions, making it a reliable choice for outdoor photography.

Price and Market Position

This price point makes it accessible for serious hobbyists who seek to upgrade their equipment while still maintaining good value for money.

Advanced Features

Photographers can rely on its consistent performance across various focal lengths, thanks to the constant f/2.8 aperture.

Conclusion and Final Thoughts

Its lightweight and compact design, combined with advanced features and a reasonable price, make it a valuable addition to Canon’s full-frame mirrorless camera lineup.


The Canon RF 28-70mm F2.8 IS STM stands out as a highly versatile lens, ideal for enthusiasts and semi-professionals.

With its advanced optical features and relatively compact design, it promises to enhance the photographic experience without the burden of additional weight.
