This lens feels like a filmmaker’s dream and a photographer’s power tool combined, offering stunning brightness and an inspiring zoom range for creative freedom. The Panasonic Leica DG Vario-Summilux 25–50 mm f/1.7 is a premium tele-zoom for Micro Four Thirds, covering an equivalent focal length of 50–100 mm in full-frame terms with a constant f/1.7 aperture throughout. Its optical construction of 16 elements in 11 groups, including an aspherical element, three ED elements, and one UHR lens, ensures exceptional sharpness, contrast, and minimal chromatic aberration. The autofocus system, powered by a linear motor, is smooth and quiet, and the AF/MF clutch gives you immediate control to switch between auto and manual focus. With a minimum focusing distance of 0.28 m at 25 mm and 0.31 m at 50 mm and a maximum magnification of 0.21× (0.42× 35 mm equivalent), you can easily capture detailed close-ups. It features a 77 mm filter thread and a 9-blade circular diaphragm that renders beautiful, natural bokeh. The body is substantial yet manageable — 127.6 mm long, 87.6 mm in diameter, weighing around 654 g — and built to withstand dust, splash, and even freezing temperatures down to –10 °C. If you’re looking for an all-in-one, high-quality zoom for both photos and video, this lens delivers professional-level performance and control.
