NiSi SWIFT 52-62mm 系統轉接環（適用於 Swift 系統濾鏡，52mm 標準螺紋 – 62mm Swift 濾鏡）

I was a little worried about whether it would fit my older 52mm lens, but the threads engaged perfectly and the machining feels precise. The bayonet mount onto the Swift holder clicks with a satisfyingly solid feel, and it hasn't loosened at all during use.

This ring clicks on securely and the threads are precisely machined. I’ve been using it to swap Swift filters between lenses, and the adapter makes the process quick and frustration-free.

I was worried the ring might not seat flush, but it clicks into place securely with zero play. The step-up from 52mm to 62mm lets me use my larger filters without any vignetting.
