You are all sooo wrong. You see, this is a trick question!
No hipster would use a camera made in Japan with interchangeable lenses... it's not a Holga or a Lomo.
If it were, then the proper strap is a $75, hand-made braided mess made from the yak hair off of a Fed 2 package fresh from Ukraine. A small portion of the proceeds must go to a group of eco-terrorists attacking missionaries trying to prevent malaria with pesticides in sub-Saharan Africa, with the bulk of the funding going, through several subsidiaries, to Haliburton and Dick Cheney's next heart, this time from a Time Lord 🙂.
Now, since it's a Bessa, a Domke Gripper 1" is appropriate. Get a forest green or an olive one.
