Yeah... that strap looks like a guitar strap at heart, and ought to work fine.
So far... and today is so far as the camera just arrived this week so that today was my first time out with it... I love it! Relative to the SLX2 it is a real step forward. Have to wait and see how the shots come out, but if they don't it's likely "on me". Even though it's technically heavier, it feels lighter because the sport grip / handle... is closer than the grip I have for the SLX. Much more refined and akin to current shooting standards... for auto. Typically I am Mr. Manual, but love to have AUTO for just "snaps". But today, since I'm thinking to get a CLA for good measure, I just wanted to put the whole through it's paces. And it really handles nicely. Well thought out. Great weather... high 60's and sunny today. So I shot about 5 rolls. With rain in the forecast for tomorrow, I'm hoping to develop a few. At the moment, the only PQ lens I have is the 80mm. But for the SLX2, I have a set 50-80-150-250 that I call my Barry Thornton Rollei Set (he had a SL66)... since I'm a fan of his work. The 250 is a shelf queen and there as a rare user. Mostly I'm a Zeiss shooter, so the Rollei sucked me into the vortex. Not sure how or why I didn't go down the Hasselblad route, but I didn't. Guess it was to have something like a Leica M6 TTL in Medium Format.
