I bought time ago the Peak Design Slide in blue (I think it's an older version). I use it for both my Canon 5d mkII and Fuji XT-2 and I'm very happy. I can change quickly the strap from one camera to another, and also adjust very quickly the length (something I do frequently and drive me nuts with the camera manufacturer straps).
I forgot the Slide at home these vacations, so I'm seriously considering to buy a second one exclusively for the Fuji. I like the Slide model because it seats very comfortable on my neck, but packing it attached to the Fuji it's a bit cumbersome.
I'm considering the Slide Little or the Leash, but then I'm afraid of the pressure around my neck, since it distributes the weight in a narrower area. I may have to check for an extra pad. Opinions and suggestions would be appreciated.
BTW, I have two cords on the right side of the Fuji, to use it as a crossed shoulder strap (when desired) without the need of a plate.
