8–18mm · f/2.8–22
The Panasonic Leica 8-18mm f/2.8-4 offers a useful 16-36mm equivalent range, balancing ultra-wide and moderate wide angles. Optically, it is sharp with minimal distortion when auto-correction is enabled, though uncorrected barrel distortion is high at 8mm. Build quality is excellent: metal construction, weather-sealed, and freeze-proof to -10°C. The lens is compact and lightweight for its class, but lacks image stabilization. It suits landscape, real estate, and travel photographers who value flexibility and robust build.
