In cooperation with Leica, Panasonic is launching a new, exciting zoom lens. Like the complementary 10-25mm, the now officially launched LEICA DG VARIO-SUMMILUX 25-50mm has a continuous minimum aperture of F1.7. In terms of dimensions and weight, the two lenses are very similar. (approx. 88 x 128mm, 654 and 690 g respectively). The focal length of 77mm is identical, of course.
As a team, the two lenses can cover a typical KB-equivalent focal length range of 20 - 100mm on the MFT mount and thus save frequent changes of the corresponding fixed focal lengths. Not only thanks to the starting aperture of F1.7 but also due to the other optical properties, the new 25-50mm should also be able to serve as a prime replacement for videographers.
In addition to silent operation due to internal focusing, the stepless aperture ring as well as the aperture change in extremely small steps help to easily adjust brightness changes when zooming or panning.
The optical design is said to provide exceptional barycentric stability to minimise image shift when zooming. The LEICA DG VARIO-SUMMILUX 25-50mm / F1.7 ASPH. also ensures high-quality video recording by minimising focus breathing as much as possible. However, an image stabiliser has unfortunately not been implemented.
The robust, dust- and splash-proof design should allow use in harsh conditions down to minus 10 degrees.
The LEICA DG VARIO-SUMMILUX 25-50mm / F1.7 ASPH. will be available in stores from August 2021 for 1,999 euros (RRP).
