Really nice lens for 5x4, not sure if it can be used on a 10x8 without barrelling….certainly movements would be restricted. I’ve used this for landscape and full/mid length portraits. It’s in good condition, speeds are all accurate. There are a few specs of dust inside and some of the paint has come off but it doesn’t affect the final image. No fungus, mould. Just found the lens caps, see last picture
