My father loved SLR cameras and used them. He's not the type to buy cheap ones. The manufacturer is mainly Kenko. Filters: 37mm 40.5mm 46mm 49mm 72mm 77mm diameter Conversion adapters: 39mm to 49mm 72mm to 77mm There are quite a few filters; I think you'll enjoy taking photos. I don't understand them as a novice, but I think there is some minor dirt. There are no scratches. Immediate purchase is welcome! No claims, no returns. I want to have a pleasant transaction! Thank you!
