Disposable cameras are a enjoyable method to get into classical images. Nevertheless, they may also be a helpful supply of fascinating components that may be put to different makes use of. For instance, as [Billt] demonstrates, their viewfinders could be repurposed right into a reasonably fascinating lens for extra critical cameras.
[Billt] was fortunate sufficient to attain a grabbag of used disposable cameras from an area movie lab, and tore them down for components. He was significantly within the viewfinders, since Kodak outfitted its disposable cameras with precise plastic lenses for this very objective.
[Billt] needed to see what these lenses would do when thrown on the entrance of a correct digital digital camera, and set about designing a mount for that objective. The 3D printed half was designed to mount one of many viewfinder lens assemblies on the entrance of any Sony E-mount digital camera. In a reasonably nifty trick, [Billt] realized the lens meeting might be put in within the adapter by pausing mid-way via the 3D print to drop it in. The one unlucky factor? The lenses didn’t actually work, and all of the digital camera might see was a haze of unfocused mild.
With assistance from some cardboard experiments, [Billt] determined to make some adjustments. The entrance aspect of the viewfinder was dumped, with the rear aspect getting used solo as a substitute. This was fitted to the adapter on a easy slide mechanism in order that focus might be reliably adjusted. With these adjustments, the lens got here good, and supplied some actually fascinating pictures. It’s fairly a cropped lens and it will possibly obtain a really shut focus distance, as little as 1 inch in testing. It’s fairly sharp within the heart of the picture, whereas softly blurring out in direction of the sides—one thing that sounds very acquainted if you happen to’ve used one in all these disposable cameras within the wild.
Typically it’s enjoyable to seize a random piece of junk to see if you happen to can flip it into one thing good. Video after the break.
