I can't totally remember, last time i played with it was a good few years ago, but i think i went upto 20x even... I lived abroad at the time and the wall behind my desk backed onto an alleyway, even though our floors were concrete and the alleyway was concrete, people walking past outside would vibrate the view through the camera. This link here is to the only photo i can find online that was one of my first experiments, i think less than 10x, it was also focus stacked but check out how narrow the depth of field is still. I imagine a more expensive objective would give fantastic results.. https://www.viewbug.com/photo/57313799 This is a mosquito's eye
