中古 Canon 77mm プロテクターフィルター - 汎用クリアプロテクションフィルター

I was a bit worried about buying a used filter, but the glass is absolutely clean with no scratches visible once mounted. It screws on smoothly and doesn't add any noticeable colour cast to my shots, which was my main concern.

Put this on my 24-70mm and didn’t notice any difference in sharpness or colour—just peace of mind. The threads screwed on smoothly without any binding, which I worried about with a used item.

Was a bit nervous buying used, but the glass is spotless and it threads onto my lens perfectly smooth. The clear protection is invisible, so I get peace of mind without any hit to image quality. Exactly what I needed for keeping dust off the front element.
