The Optical Structure
To provide such a high-quality image, Panasonic has used a highly advanced and complex optical structure that’s built to Leica Camera AG’s strict quality standards. It comprises 16 premium glass elements arranged into 11 groups, including the use of 1 aspherical lens, 3 extra-low dispersion lenses, and 1 UHR element. These additional elements have been implemented to suppress the appearance of colour fringing, chromatic aberrations, and spherical aberrations, resulting in high levels of clarity, sharpness, and colour accuracy. This is complemented by a super-bright, fast and constant f1.7 maximum aperture that not only excels in low-light conditions but is capable of producing smooth and pleasing bokeh.
When it comes to performance, this lens has been designed to excel with both stills and video capture. The lens is fitted with a Linear AF motor and an internal focusing system that together can deliver impressive fast and quiet focusing performance. As well as this, this design results in next to no focusing breathing throughout the entire focusing range and the optical mechanics offer exceptional barycentric stability minimising image shifts during zooming. This, and the addition of a stepless, de-clicked aperture ring that offers smooth and silent aperture adjustments, makes this lens ideal for video purposes. Furthermore, Panasonic has included a focus clutch mechanism that allows for easy switching between AF and MF modes.
That looks familiar?
Mirroring the aesthetics of the ever-popular Leica DG Vario-Summilux 10-25mm f/1.7 ASPH. lens, this Panasonic Leica DG Vario-Summilux 25-50mm incorporates near-identical exterior dimensions and weight. Further to this, they also share the same 77mm filter ring diameter and utilise unified colour rendering to guarantee flawless switching between both lens types. In essence, this 25-50mm lens stands as the second half of an enhanced two-lens zoom system. By doing so, you can easily and efficiently switch between this lens and the wider 10-25mm without having to change internal camera settings or even adapt your shooting stance. Both lenses employ unified colour balance, consistent image quality, matching bokeh rendition, and resolution to support 4K video. For filmmakers, their identical centres of gravity and overall form factors also make swapping lenses out of a video rig incredibly fast and hassle-free.
