if i could comfortably fit the gear i want (gripped 5d3 and now a 5d4 too) 24-70 f2.8 and 70-200 f2.8, and a speedlite and my 50 f1.4 and 1.4X tc in my dark brown 1984 vintage F2, id still carry it all in that. i used to have a pair of F1-n bodies, 24 f2, 35 f2, 50 f1.8, 85 f1.8, 200 f2.8, speedlite quantum battery, and 8-10 rolls of film (both color and b/w) in that bag...
digital gear is just so much bigger and heavier, i had to move to an F-7 double (about the same footprint but definitely deeper) and ive got an f1x or something which is about the same height as the f2 but longer... they just dont fit ME the way the f2 does and neither of the have the velcro on the top flap and across the pockets to "lightly secure" the top flap. i need to rectify that...
-im just trying. sometimes i succeed
