● This is a variable ND filter. Adjustment (variable) is possible between "ND2" and "ND400". It's an ND filter used for purposes such as "when you want to slow down the shutter speed" or "when you want to open the aperture and blur the background." ● After attaching this filter, you can attach another filter on top of it. In that case, it will be the next size up, 55mm. Also, when attaching a front cap, the front cap size will be 55mm. (Front cap is not included, but is listed separately.) ---------------------------- ※ This "variable ND filter" is available in sizes 40.5, 43, 46, 49, 52, 55, 58, 62, 67, 72, 77, and 82mm, but the specifications vary depending on the size because the manufacturers are different. ※ You can attach it to any camera lens from any camera manufacturer as long as the filter thread size matches, so please feel free to consider it. ※ I check the entire lens before listing, but please refrain from purchasing if you are seeking perfection. There is no dedicated case or box, but I will pack it carefully. ※ This series includes "ND2", "ND4", "ND8", "ND16", "ND1000", "ND2-400", and "ND2+ND4+ND8 set of 3" types. (Each is currently listed.) ********************************* ↓↓ Common product description from here ↓↓ ■ If you can't find something you're looking for, or if you're purchasing multiple items, I will create a "dedicated page" with a discount for the shipping cost, so please feel free to comment. ■ There may be some changes to the design.
