Due to rising material costs, we have increased our prices. Thank you for viewing. *Please read the entire text before proceeding. This is a half soft filter created with a width of 100mm x height of 150mm and a thickness of 2mm. It is made with a 7:3 ratio of a soft-effected area to enhance stars and an unaffected glass area. The soft effect makes stars stand out, while the lower part captures sharp images without losing resolution, making it an essential filter for astrophotography. It does not have a starry night (light pollution cut) effect. Example photos taken with this filter are included for your reference. (Please consider these as a guide, as camera settings and retouching methods vary for each individual.) Regarding filter holders, I have used a Kani filter holder, and it worked without any issues. (The lens in the image has a 82mm diameter.) We sincerely apologize, but we cannot offer any further price reductions. As this is a handmade filter, please refrain from purchasing if you are looking for a perfect product, and instead purchase one officially released by a manufacturer. *We will ship with the utmost care, but we cannot be held responsible for any damage that may occur during shipping. Please understand. *Please be careful not to scratch the soft-effected surface with your nails or hard objects, or to wipe it with a wet cloth or while it is wet, as it may peel off. We recommend avoiding touching the soft-effected surface as much as possible. *As this is thin glass, it is very fragile. Please be careful of injuries when opening or using it. We cannot be held responsible in the unlikely event of an accident. *There may be minor scuffs or small chips on the edges of the glass due to individual differences. *Depending on the holder, there may be slight individual differences in tightness or looseness when attaching the filter. *No claims, no returns. #halffilter #softfilter #lens #lensfilter #squarefilter #DSLR #mirrorless #camera #NDfilter #PLfilter #MilkyWay #starrysky #prosofton #nightview #SONY #Nikon #Canon #TAMRON #SIGMA #Sony #Nikon #Canon #Tamron #Sigma #Kenko
