The trusty professional standard zoom as gone from 35mm to 70mm to 24mm to 70mm. Canon then made life interesting producing a range of professional zooms, a little slow but more range. The Canon 24-105mm f/4 has long been popular for Canon users.
Nikon finally copied and improved with their recent Nikkor Z 24-120mm f/4 which has been a sellout.
Now Sony are getting in on the act and have just announced a very interesting lens. a 20-70mm f/4 zoom. So for people who generally prefer to go wider but still need that reach into the mid short telephoto range a great lens for them.
