Fujifilm XF 23mm f/1.4 R Lens

It’s $20 more on amazon, and you get 2 day shipping. Not much of a deal here.

Cameras like the X-Pro 2 don't have much of a grip, like Leicas. I found it more convenient to use my peak design slide, and almost never use my wrist strap, just because it isn't the most ergonomic thing to hold for a long period. Slide lite or leash is perfect for Fuji lenses. Ironically, I found that I use a wrist strap with my Nikon DSLR more, probably due to ergonomics. Don't get me wrong, Fuji's ergonomics are fine, but a camera that small is just hard to hold onto sometimes.

Thew slider strap is an odd choice to go with a Fuji lens. Fuji cameras are on the small/light side of the spectrum. Especially compared to Canon/Nikon DSLRs. A hand strap or wrist leash might be more practical. Or possibly one of the aftermarket slip on cases.
