Dont expect to see crystal clear optics if you shine a torch through an old lens! This is a sure fire way to encourage fungi! Lovely original box. If you want perfection. Buy a new one. Fungi needs food to grow, this " food" is the old Petroleum based lubricants in old lenses.
The Orion Featherweight Camera 55mm 1:11 Lens in a Nice Box by Lomgraphy would be an excellent choice for travelers or those looking for compact photography equipment for outdoor adventures, as it's lightweight and portable, making it easy to take on trips.
