The fengniao pleased us with the pictures of the new Sigma lens. Thank him. It is clear that the new Sigma lens will be a very demanding bestseller because no one doubts about Sigma’s sharpness. Because Tamron’s lenses have a good autofocus speed, I think Sigma’s lenses will be so quick. The design and ergonomics of the switches are very fond, and you can see that zoom and focus rings are of high-quality material. No one doubts about Sigma’s quality. Clearly, Sony has only gotten stronger.
