What We Like
+Extremely compact and lightweight at 440g with f/2.8 constant aperture
+Excellent sharpness throughout zoom range, nearly matching premium 24-70mm GM II
+Smooth, creamy bokeh from 11-blade circular aperture
+Superb close-focus performance with 19cm minimum focus distance
+Versatile focal range ideal for travel, street photography, and video work
Worth Knowing
−Significant barrel distortion at wide end requires in-camera correction (non-disableable in RAW)
−Pronounced lens breathing during focus pulls, limiting video flexibility without breathing compensation
−Narrow zoom range (24-50mm) sacrifices 70mm coverage compared to standard 24-70mm lenses
−No optical image stabilization, relying solely on in-body stabilization
