no order in my case ... even if the 85L could be sufficient by itself.
TSE 17L4.0 (100% lanscape)
24L1.4II (walkaround and indoor life)
85L1.2II (sticked for any uses in the life like for my last 20 years with FD85L1.2 portrait, action/sport, landscape, ... )
200L2.0 or 300L2.8ISII (sport and portrait)
I missing a good WA macro lens .. I use sometimes a sigma 24F1.8
But of course 2 bodies FF and APSH, so it makes 8 lenses in real life..... that's all !
