Which one is better, Shenglang lens or Yongnuo lens?

Yongnuo lenses are good.

1. Good texture. The Yongnuo lens is very smooth, clear, has high pixels, the lens texture is very good, and feels heavy in the hand, while the Shenglang lens has low resolution and unclear image quality, so the Yongnuo lens is better.

2. Good focus. The focus ring of the Yongnuo lens is very smooth and full of wide-angle, with no blur or sound. It is sharp inside the focus and soft outside the focus. However, the Shenglang lens can only be used to shoot immobile objects and cannot focus when the distance is far. So Yongnuo lenses are good.
