Please note: Agena only sells DGM's "first quality" filters. However, it is our experience that even their first quality filters often have pinholes, sleeks, and/or light scratches. These flaws will have no impact on optical performance and the spectral characteristics of the filter are not compromised. DGM occasionally sells "cosmetic seconds" via their website. We do not sell DGM's cosmetic seconds but please be aware that your first quality DGM filter purchased from us might still have some minor pinholes, sleeks, or light scratches. Despite these imperfections, we believe that DGM filters offer a great value at their price point.
