🧑‍🎤 Canon Ef 24 105Mm F 4L Is Usm Vs 24 105 Stm

Old 24-105mm F/4L still worth it? So it turns out you can get a used 24-105 F/4L IS USM lens for about $320-400. Is it worth it at that price? My current main lens is the EF-S 18-135 F/3.5-5.6 IS nanoUSM. Shooting on a Canon 7dMk2 (though I'd like to upgrade to a C100 mkii at some point). A9QxW.
