Thank you for viewing! This is a Kenko PRO1 F Pro Softon Clear (W) 62mm diameter filter. By screwing it onto a 62mm diameter camera lens, it's a lens filter that makes constellations stand out while keeping the landscape clear during astrophotography. There are Pro Softon A and B, but this is "Pro Softon Clear." Please be sure not to make a mistake. By the way, according to the manufacturer's website, the difference between A and B is: "Use 'Pro Softon Clear' when you want to 'avoid blurring the landscape' and 'subtly bring out the constellations,' along with 'Pro Softon (A)' which has a weaker effect, or 'Pro Softon (B)' which has a stronger effect." Reference manufacturer website (image samples available): https://www.kenko-tokina.co.jp/lp/prosofton-clear/ I used it about twice for astrophotography in the summer of 2026, but I no longer need it because I changed lenses (Tokina 20mm f2). I will sell it to someone whose filter size matches. It looks clean and has no scratches. However, please consider it as a used item. The only included accessory is the case. I will wrap it in cushioning material and send it via Yu-Packet Post Mini.
