Photography: Peak Design quick detach clips, strap and baseplate.
Photography is just a hobby for me, so I tend to lean towards 3rd party lenses and accessories that have a good price to quality ratio. I can not overstate how substantial a difference these clips and straps have made for me. There is no comfortable way for someone to hang a camera around their neck or over their shoulder for more than a few hours with the OEM straps, let alone a full day. With these things I have backpacked multiple long weekend trips, taking my camera out of my bag in the morning and having it out all day. I can transition from a cross body dangle, to hanging from my backpack strap in seconds which is critical if I need to free my hands quickly.
Love these things.
