Ring structure macro particle is distributed on grid by the volume-weighted model method and can be more accurate than face-weighted method.

在该程序设计中，宏粒子采用环宏粒子模型，用体积加权模型将每一个宏粒子电量分配到格点上，相对于面积加权模型更加精确。

Additionally, it features a macro switching ring on the lens barrel which instantly shortens the minimum focusing distance to approximately 20cm (from image plane), allowing the camera to capture small, close-up subjects with exquisite detail.
