The video was recorded on August 13, 2020. Severe smoking occurred when the lens was out of focus at first; due to the pandemic, no photos were taken during the period when no measures were taken to address this issue. Currently, only videos of the situation after those measures were taken are available, and by fast-forwarding these videos, it is possible to see that almost no smoke or dust is visible at the moment of out-of-focus condition.
