Sigma may release an unprecedented new telephoto lens

Sigma may release an unprecedented new lens. Recently, the president of Sigma revealed in an interview that Sigma is developing a new lens, which is an "unprecedented" telephoto lens, focusing on sports photography and ecological photography. It is very attractive and is being developed with full efforts. More parameters and specifications and specific release time cannot be disclosed for the time being. (It is likely to have Sony E and Leica L mounts)

I don’t know if photographers are often disturbed by the reflected light from the water when using telephoto lenses, especially when photographing birds. Now, buy the K&F CONCEPT CPL filter to filter out the stray light reflected from the water surface and make the bird’s feathers more colorful.
