I don't know the specifics. I don't really know what they're for. Mostly, they seem to be Kenko lens filters, but there might be a couple that are different. The frame is detached from the 67mm lens. Two are detached, but I stopped investigating further. Others might be detached as well. There might be scratches, but I'm not sure, so please take them as a set. The one in the Tamron case seems to have quite deep scratches on the lens. For those who are interested, please.
