Apa itu step up ring?
Step up ring merupakan aksesoris lensa yang berfungsi untuk memperbesar ukuran diameter lensa kamera. Misalnya begini, kita punya lensa kamera dengan diameter lensa 49mm, tapi masalahnya filter yang kita punya memiliki ukuran 52mm, maka solusinya biar filter tetap bisa dipakai di lensa dengan diameter 49mm, maka kita perlu step up ring 49mm to 52mm.
