Panasonic Lumix G 25mm f/1.7 Asph Black

Panasonic Lumix G 25mm f/1.7 Asph Black – Compact 25mm Prime with F1.7 High-Speed Aperture

This Panasonic LUMIX G 25mm f/1.7 Asph is a compact, lightweight prime lens that delivers a high-speed f/1.7 aperture. The large aperture produces attractive soft focus for both photo and video and enables shooting in dimly lit conditions without using a flash.

Natural 50mm-Equivalent Perspective

The lens provides a 25 mm focal length, which is equivalent to 50 mm on a 35mm camera. Therefore, it offers a natural viewing angle close to the human eye. As a result, you can use it for a wide variety of occasions and change composition freely—more dynamic or up-close—according to your subject.

Optical Design and Image Quality

The optical system consists of 8 elements in 7 groups. It includes two aspherical lenses and an Ultra-High Refractive Index (UHR) lens. Designed with a focus on low-frequency contrast, the lens aims to deliver clarity and sharp, crisp images. It maintains uniform descriptiveness from center to edges while suppressing spherical aberration and distortion.

Focus System and Video-Friendly Features

The lens incorporates a superior inner focus system that supports excellent resolution and contrast from the closest focusing distance to infinity. In addition, a stepping motor drives autofocus, producing smooth and silent focusing action suitable for both photo and video recording. When you mount this lens on LUMIX G DSLM cameras, you can take advantage of the high-speed, high-precision Contrast AF system with a 240 fps digital signal exchange.

Aperture, Build and Coatings

The aperture uses seven blades to create a rounded shape, which produces an attractively smooth effect in out-of-focus areas at larger aperture settings. The lens features a highly reliable metal mount for durability during active use. Furthermore, multi-coated lens elements minimize ghosts and flare to enhance shooting performance.

Use Cases

• Shooting in dimly lit environments without a flash, thanks to the f/1.7 aperture.
• Natural-looking general-purpose photography with a 50 mm-equivalent perspective.
• Photo and video work that benefits from smooth, quiet autofocus driven by a stepping motor.
• Situations that require consistent sharpness across the frame, from center to edges.
