This is a Vivitar 28 - 210 Zoom Lens F3.5 for the Praktica Bayonet. The lens is in really good condition with clear optics and no fungus although there is a tiny amount of dust inside, as is normal for its age. This does not effect anything. I have lubricated it and it is very smooth and focuses well and the aperture is smooth. It has been film tested and produces really good images. It has a lens cap and bayonet cap. If you have any questions, please ask.
