This is a 72mm filter that allows you to take IR Chrome-style photos. It is not a genuine Kolari Vision IR Chrome filter, so the quality and color reproduction will differ. Please consider this as a practice or trial filter. I used this temporarily before purchasing the real one. It is a used item. There is some fine dust and minor scratches, but it does not affect photography. > Requires a full-spectrum modified camera to use > Recommended for beginners / trial use > We cannot accept claims regarding product quality (due to being manufactured by NANTONG FORIC) ※ Can be attached to 72mm diameter lenses. Recommended for step-up rings. ※ Please check the images and only purchase if you are satisfied To prevent any issues, please refrain from purchasing if you are seeking perfection or have any concerns.
