How To Make A Working Lens Out Of Sand And Rocks

If you are particularly keen to difficult DIY projects, this one may be for you.

Andy George of How To Make Everything redefines the concept of DIY with this project: a lens build from scratch using raw sand, rocks, and metal, and a huge amount of skills too, I guess.

Previously, Andy built a pinhole camera, as you can see in the video below.

Not satisfied with the pinhole camera, Andy decided to build a lens from the scratch. Well, it took him a dozen attempts before getting it done right. Guess making your own glass isn’t everyone’s thing. The video below explains all steps. Enjoy.

Therefore we are probably one of the youngest photographic companies that have received such an award and recognition from the world’s oldest independent design organization, the Hannover-based iF International Forum Design GmbH, a group which organizes the iF PRODUCT DESIGN AWARD.

Learn How To Clean Your Lens With A Candle, A Spoon And A Lens Cleaning Cloth

Not sure if you should try this at home though it worked for Mathieu Stern as you can see in the video below.

What is it about? Instead of using a lens cleaning pen, you can do the same job with a candle, a spoon and a microfibre cleaning cloth. The tip of a lens cleaning pen is covered by “carbon cleaning compound”, which basically is soot. Soot sticks to oils and fats and hence works perfectly with those fingerprints on your precious lens. What is shown in the video is how to make your own “carbon cleaning compound”.

Watch the short video below carefully before trying it. Be aware that soot is a gentle abrasive, but still an abrasive. Using this trick too often might damage the lens over time (though it seems to work fine for Mathieu Stern).
