Don't listen to anyone who belittles this lens except because of the price! I'm a professional with 30 years of lens sampling experience. This SHARIE lens is wide open. Some barrel distortion at 24mm but easy to fix. Good colors and fantastic bokeh with 9 petals. IS works fantastic on the new A7R3 and focusing is very fast. The weight isn't an issue and the size is very comfortable given the zoom range. Also great for portraits. Here is SOOC .jpeg
