二手 DSLRKIT 金屬腳架環 D(B)（Canon EF 100mm f/2.8L Macro IS USM 用）

I was worried a used mount ring might wobble, but the D-shaped adapter plate locks on tighter than I expected. It really stabilizes the 100mm macro during close-up focusing.

Screws onto the lens perfectly and the metal feels solid, no wobble at all. I've been using it handheld and on a tripod for macro shots. Saves me from buying a new collar for this specific Canon lens.

Was nervous buying used, but this mount ring fits my macro lens perfectly with no wobble at all. The metal build feels solid and the locking mechanism clicks in tight every time. Exactly what I needed for steady tripod shots.
