I tried the reversed macro lens way back in 2012 for the first time. Back then, I first photographed things that mostly weren't moving at all or just very little. Turned out that the world is really interesting when you look at it from a close perspective, even the non-living things. Drops on a DVD disc, bubbles in a water bottle, concrete, electronic components, mechanical instruments... all of that can look very different from normal when you get closer. And a double ratio reversed lens is more than enough for this. To be honest, I haven't stopped taking macro pictures entirely, especially when it came to colder months of the year when you couldn't find insects and plants alive in nature. Instead, I used artificial objects, which you can photograph anytime at home.
