I skipped posting on Sunday, so I'm double posting today.
Here are a couple new photos from my macro set, the top photo is the aperture and focus rings on a Yashica f1.4 38mm lens made for a made for an old 8mm camera. Since I don’t have a camera for this lens it makes a great paperweight.
Below are the actual blades of the aperture mechanism. This lens is great for explaining what aperture is since the blades are so easy to see.
