[This series will feature chapters that showcase key lenses in the LUMIX S Series lineup—built for photographers and filmmakers who demand high quality, consistency, and creative flexibility. At the top of the lineup is the S PRO series, offering the highest level of optical performance, precision, and expressive power.]
The LUMIX S PRO 24-70mm F2.8 is a standard zoom lens built for professionals who need flexibility without compromising image quality. Whether capturing portraits, landscapes, events, or video, this lens is designed to deliver consistent results across a variety of scenes.
When LUMIX set out to design this lens, the goal was to create a reliable, high-performance lens that meets needs in both still videography and photography. It was also designed to meet the strict standards required to earn “Certified by LEICA” approval, which showcases its high optical and mechanical quality.
Balanced Optical Performance
A key part of the lens design was achieving high resolution throughout the zoom range. Many standard zoom lenses tend to lose sharpness at the edges or at certain focal lengths, but the S PRO 24-70mm F2.8 maintains sharpness from corner to corner, whether at 24mm or 70mm, and at all apertures.
In addition to resolution, bokeh was carefully considered. Smooth background blur helps isolate the subject and adds depth to images, and this lens was designed to produce a pleasing, natural bokeh. The optical design also keeps peripheral aberrations under control, so that even points of light in the background appear clean and free of harsh outlines.
Color reproduction was another priority. Chromatic aberration — which can cause color fringing around high-contrast edges — is minimized using four ED (Extra-low Dispersion) elements strategically placed inside the lens. These elements help maintain true-to-life colors and contribute to higher overall resolution by preventing color bleed.
Chromatic aberration is minimized through the use of ED (Extra-low Dispersion) lenses, ensuring sharp, high-contrast images with accurate color reproduction.
Advanced Focusing System
One of the standout features of this lens is its double focus system. Instead of moving a single focus group, this system moves two lens groups simultaneously. This improves autofocus speed and accuracy, and it helps maintain a flat image plane, so subjects stay sharp across the entire frame even at close focus distances.
A flatter image plane is especially important for portrait and product photography, where edge-to-edge sharpness and controlled depth of field are critical. In video, the double focus system also helps reduce focus breathing — a shift in angle of view when focusing — which can be distracting when recording motion.
The dual focus system benefits from LUMIX's expertise in electronic control, originally developed in the Micro Four Thirds system and refined for the full-frame format. By electronically coordinating the two focusing groups, the lens achieves precise movements that are quiet and smooth, essential for professional video work.
The double focus system enhances AF speed and accuracy while keeping subjects sharp across the frame—even up close.
Sophisticated Zoom Construction
The internal construction of the lens is complex, using seven moving lens groups arranged to maximize optical performance at every focal length. The arrangement includes a positive-negative-positive pattern with additional groups added to further control aberrations and maintain consistent image quality throughout the zoom range.
This design allows the lens to perform reliably, whether shooting wide open at F2.8 or stopped down for greater depth of field. Even at close focusing distances, sharpness and contrast are preserved.
The use of multiple moving groups and specialized glass materials adds manufacturing complexity, but it’s a key reason the lens delivers consistent results in challenging conditions. The design also reflects careful collaboration between optical and mechanical engineers, ensuring that every element works in harmony.
Designed with bokeh in mind, the lens delivers smooth, natural blur that enhances subject isolation and image depth.
Designed for Real-World Use
Beyond optical performance, the S PRO 24-70mm F2.8 was built to be a dependable tool in the field. It features a robust, weather-sealed construction to handle outdoor shoots and tough environments. The lens is also designed to work seamlessly with LUMIX camera bodies, supporting fast, accurate autofocus and smooth aperture control.
For creators who need one lens to handle a wide range of subjects — from spontaneous moments to carefully planned portraits or video sequences — the 24-70mm F2.8 stands out as an essential choice. It embodies LUMIX's commitment to combining precision engineering with practical usability.
