I have a new lens, a Viltrox 9mm 2.8. Took a test run the other day through raindrops and will do more today. Because it is such a wide angle, it lets you get really close to the subject with minimal distortion with 'flatter' subjects like this puddle. You can see that the camera focused on everything, not just the reflections, so all is clear. I am happy with it so far.
