Canon RF 24-70 f/2.8 – Standard Zoom Lens
The Canon RF 24-70 f/2.8 L IS USM lens represents the heart of Canon’s professional zoom lineup for mirrorless cameras. Designed for the EOS R system, this lens offers the perfect blend of optical excellence, speed, and durability.
Its bright constant f/2.8 aperture allows you to shoot in low light and achieve a stunning depth of field across the entire zoom range. The lens also includes Canon’s advanced optical image stabilization, which provides up to 5 stops of shake correction, making it ideal for handheld shooting in tricky lighting.
Detailed Overview
This lens is part of Canon’s elite “L” series, meaning it’s built with top-quality optics and materials. It includes a Nano USM (Ultrasonic Motor) that delivers fast, silent, and precise autofocus performance, essential for both still photography and video recording.
The control ring on the barrel allows quick adjustments to ISO, aperture, or exposure compensation without diving into menus. The optical construction includes advanced lens elements and coatings that minimize flare and ghosting, even when shooting in bright or backlit environments.
With a minimum focusing distance of just 0.69 ft at wide and 1.25 ft at telephoto, the RF 24-70 lets you get closer to your subject, capturing fine details with exceptional clarity.
Its weather-sealed design keeps dust and moisture at bay, making it suitable for outdoor and professional work. The lens feels well-balanced on Canon’s full-frame mirrorless bodies like the EOS R5, R6, and R3.
What Is Good
The Canon RF 24-70 f/2.8 delivers exceptional sharpness and contrast across the frame. Its image stabilization system gives you more freedom to shoot handheld, especially in low-light environments. The autofocus is nearly silent, which is ideal for video shooters.
The customizable control ring is another plus, letting you quickly adjust critical settings without distraction. The build quality is rugged yet refined, and the lens provides consistent performance across all focal lengths.
What Is Bad
The main downside is the price, as this lens is expensive even for professionals. It’s also slightly heavier than its competitors, which may affect portability. While it’s superb for stills, video shooters may notice a bit of focus breathing during focus pulls, though this is minor compared to older Canon lenses. Some photographers might prefer even lighter options for travel or documentary use.
Overall Verdict
The Canon RF 24-70 f/2.8 is a powerhouse lens that lives up to its “L” series reputation. It’s sharp, fast, and reliable in almost any shooting scenario. The combination of optical stabilization,
Nano USM autofocus, and intuitive control features makes it an excellent investment for serious Canon users. If you shoot with an EOS R camera and demand professional results, this lens remains one of the best choices available today.
Sony FE 24-70 f/2.8 GM OSS II – F2.8 constant aperture Standard Zoom lens
The Sony FE 24-70mm f/2.8 GM OSS II is Sony’s latest upgrade to its flagship standard zoom. It combines advanced optics, lightning-fast autofocus, and exceptional portability. Sony’s G Master line has long been praised for its image quality, and this version brings major improvements over the original.
It’s designed for both stills and video, offering superior sharpness, reduced focus breathing, and enhanced control. This lens targets professionals who demand consistent, high-end performance from their full-frame Alpha cameras.
Detailed Overview
The Sony FE 24-70 GM OSS II features two XA (extreme aspherical) elements, two ED glass elements, and two Super ED glass elements that work together to eliminate chromatic aberration and distortion. This advanced optical design ensures edge-to-edge clarity even
when shooting wide open at f/2.8. The floating focus mechanism and improved coatings further enhance contrast and color accuracy. The result is a lens that produces incredibly detailed and vibrant images in every frame.
Despite its professional-grade optics, this lens is surprisingly compact and light. Weighing just 695 grams (24.6 oz), it’s over 20% lighter than its predecessor. The smaller size makes it a perfect companion for long shoots or
handheld videography. Autofocus performance has also evolved dramatically, powered by four XD Linear Motors that deliver ultra-fast, precise, and quiet focusing. Whether you’re shooting stills at 30fps or recording 4K 120p video, the lens tracks subjects effortlessly.
What Is Good
The Sony FE 24-70 GM OSS II excels in clarity and contrast. It’s one of the sharpest zooms Sony has ever made, with outstanding color rendition. The lightweight design makes it far easier to handle than other pro lenses in its class.
Autofocus is blazing fast and whisper-quiet, which is great for hybrid shooters who do both photos and video. The new aperture unit allows smooth, clickless control, enhancing creative flexibility for filmmakers.
What Is Bad
Its biggest limitation is the absence of built-in optical stabilization, which some users expect at this price point. While most Sony bodies offer in-body stabilization (IBIS), videographers using gimbals or
older cameras may still notice this gap. Another point to consider is the premium cost, which places it at the high end of the market. However, its lightweight construction and improved features justify the investment for serious users.
Overall Verdict
The Sony FE 24-70 f/2.8 GM OSS II is one of the most advanced zoom lenses available. It’s sharp, compact, and optimized for both photos and video. The autofocus system is among the best in its category,
and the reduced weight improves overall handling. Sony’s focus on innovation makes this lens a top pick for professionals who want maximum performance without compromise.
