محول NiSi لعدسة Sigma 12-24mm f/4 HSM ART لحامل فلاتر NiSi 180mm

Was a bit worried about compatibility, but the aviation-grade aluminum build feels solid and it locked onto my 180mm filter holder without any issues. Exactly what I needed for my Sigma 12-24mm f/4 ART lens.

For the price of a clearance item, this adapter is machined beautifully—the aviation-grade aluminum threads engage smoothly with the filter holder, no wobble at all. Only minor quibble is that the included instructions are sparse, but the fit is perfect on my Sigma 12-24mm.

The milled aluminum feels rock-solid when I lock the holder on, and the fit on my Sigma is exactly tight with zero wobble. Sure, it's clearance stock, but the machining quality doesn't show any corners cut.
