For me it is indispensable and universal. Has pros: It perfectly replaces a set of lenses 24-70 + 70-200, which you can carry around all day, just your back falls off (only 70-200 pulls one and a half kg. Excellent sharpness over the entire FR range. I am pleased with both color reproduction and focusing speed. Saved me from the need Constantly change lenses while shooting. Cons below: I could not stand shooting without a flash in a concert hall. Too dark. I had to use his more aperture colleague. The degree of background blur, of course, is inferior to faster models and fixes. But on large FRs it’s very decent.
