Here's a listing for a Pentacon 49mm screw-in G1 filter, which can be surprisingly hard to find. There are some minor scratches and dirt, but I didn't notice any impact on actual photos. No returns or exchanges. Will ship with simple packaging. Please refrain from purchasing if you are overly concerned about condition. #zeiss #49mm #g1filter #monochrome filter #silver frame #protective filter #ihagee #praktica #pentacon #pentacon #madeingermany #m42 #cameraaccessories #lens #oldlens #lensaccessories #filter #lensfilter #eastgermany
