I used to use the Peak Design connectors with one on the lens and one on the camera. There was another thread in this forum that discussed
Safe ways to carry a large lens with a strap? (Where to attach strap.)
and I determined that my method probably wasn’t the optimal approach. I tried the Magpul strap with QD on the RRS foot that I had on the lens. But I didn’t like the balance. The FTZ adapter moves the lens further away from the camera and so the balance point is upset.
@Patty15 mentioned the Hejnar foot specifically for the Z9 and 500PF in that thread, so I purchased it. It hangs very comfortably and balanced. So far so good. And kudos to
@Patty15 !
