I recently got, from someone on Freegle, an old Pentax S1 film camera. With the camera came a box containing various old enlarger lenses, but there was also a 10cm diameter simple glass lens. It’s flat on one side and convex on the other. Having played with it a bit I realised it would make a great “accessory lens” for the camera on my Samsung Galaxy Tab. I found that if I set the Tab’s camera to Macro and held the lens in front of the Tab’s own lens, I could focus really close.
Here’s one of my first tries. These two fuschia flowers were part of a hanging basket and looked great in the morning sun. There was, however, a quite strong wind which was blowing them about and making it hard to focus and frame. I decided to take advantage of the sunshine, but inside rather than outside in the wind.
We have a beautiful Phalaenopsis orchid, so I put it in the sun and part closed the curtains so only the orchid was lit. This made the background nice and dark. I turned the orchid round to give good cross lighting texture and a strong shadow, and framed nice and close to capture the detail of the flower. The highlight on one part of the flower is a bit burnt out, but that’s always an issue with small sensors.
I reckon that for a free lens it’s a good buy, so why not check out Freegle yourself? Who knows what you might find!
