Review on Canon EF 24-105mm f/3.5-5.6 IS STM Lens, 9521B002: Versatile Zoom Lens for Superior Photography by Carrie Porter

Bought this lens for my Canon 6D. I liked it very much. Better picture quality than pro reviews. Also slightly lighter than the f4 version and quieter. Colors looked very good and sharpness was good in the center across the range, maybe a bit softer in the corners but that's not a problem. Worked very well for portraits and casual outings. Would have kept it but due to the size opted for a very good Canon 24-85mm copy. I don't like carrying heavy gear!
