What Buyers Say
Panasonic Lumix G Leica DG Vario-Summilux H-X1025 10-25mm
The Leica 10-25mm F1.7 is widely praised for its exceptional sharpness, beautiful bokeh, and robust build quality, making it a top choice for both photography and video on Micro Four Thirds cameras. Users highlight its constant f1.7 aperture, smooth manual focus clutch, and click-less aperture ring as standout features. However, it is noted as large and heavy for the system, with a high price and no optical stabilization, and some report autofocus hunting in video mode. Despite these drawbacks, most consider it a spectacular lens that delivers uncompromising image quality.
