Nice DIY adapter! I also use the S5 mini since shortly (with the Kowa adapter
) and I'm equally pleased with the results. E.g. this video here: https://youtu.be/5eYJv884Xxo
As the camera of the S5 mini has rather modest specs, I wonder what can be done with the better phone cams of S5, S6 or Sony Xperia Z5...
While the image quality does not really superpass my previous set up with the Canon S95 compact camera, the ease of use is way better. As everything is more compact and much lighter, the entire handling is easier. There are much less vibrations when taking a pic by slightly touching the screen (or even without touching at all by using the speech control), so no time lag is needed as with the compact camera. Also zooming in and out is easy and intuitive. And a surprise bonus is that the screen view also allows for easy sharing of the view simultanously with several observers.
