Panasonic Lumix S PRO 50mm F1.4
Only one whitelisted tester, Digital Trends, published hands-on impressions of this exact lens, within an L-mount roundup where it is named the best portrait option. It praises excellent image quality, sharpness on high-resolution bodies, and a top-notch weather-sealed 'Pro' build, while flagging the near-Leica price and the 2.1-pound, over-five-inch size. (1 sourced review.)
Praised: Excellent image quality and superior sharpness, even on high-resolution bodies; Top-notch, weather-sealed 'Pro' build with a sturdy feel and manual focus clutch; Bright f/1.4 aperture with 11-blade diaphragm for low light and circular bokeh.
Flagged: Price approaches Leica territory; Large and heavy for a 50mm (2.1 pounds, over five inches).
