The Panasonic 25mm f/1.7 is a compact normal-range lens for Micro 4/3 cameras. Key features include:
Great for street, landscape, and general-purpose photography
Excellent for low-light shooting
Fast, smooth, and nearly silent autofocus
Seven-blade curved aperture diaphragm
Standard Focal Length. With a focal length equivalent to 50mm after sensor-crop factor, the Panasonic 25mm is a great normal-range lens. Its normal perspective is great for street, landscape, and general-purpose photography.
Fast Aperture. The fast f/1.7 aperture works well for low-light shooting and enables better depth-of-field control than a kit lens. A rounded seven-blade diaphragm produces a smooth bokeh when working with shallow depth-of-field techniques.
Stepping Autofocus System. Its stepping motor delivers fast, smooth, and nearly silent autofocus performance to benefit both still photograph and movie recording applications and is compatible with Lumix cameras’ contrast-detection focusing systems.
Sharp Optics. One ultra-high refractive index (UHR) element and two aspherical elements help to reduce chromatic aberrations and distortions for consistent edge-to-edge sharpness and illumination. This design also helps to maintain a compact overall form factor, measuring just two 2” in length and weighing 4.4 oz.
