قاعدة العدسة Sigma TS-81 لعدسة 150-600mm f/5-6.3 DG OS HSM Sport

Switched to this foot for my 150-600mm and the solid metal mount locks in tight, completely eliminating any play I had with my old adapter. Now my setup feels rock-solid even with the lens fully extended.

Finally got this foot for my 150-600mm and it's a huge upgrade from the plastic original—the metal base feels rock-solid on my tripod plate.

Fit is spot-on for the Sport lens, and the Arca-Swiss dovetail locks into my clamp with zero play, which is a relief after dealing with a wobbly third-party plate. It’s pricey for what is essentially a block of metal, but the machining is clean and the stability when panning feels noticeably more so
