Nikon today unveiled the upcoming DF-M1, a red dot sight designed for photographers who shoot fast and unpredictable moving subjects with super-telephoto lenses.
“With super-telephoto shooting, a narrow field of view in the viewfinder tends to be made visible – making it easy to lose track of the subject,” Nikon says.
The Dot Sight DF-M1 is a hot-shoe-mounted designed to solve this problem by allowing photographers to track fast-moving subjects through the dot sight instead of the viewfinder. By keeping the red dot on the subject, a photographer can ensure that they’re maintaining the topic within the frame of their photos and videos.
It’s a product that “makes it easy to keep tabs on the intended subject within the framework, even if the subject exhibits sudden movement,” Nikon says.
Here’s How it looks like: 
As the release date for the Nikon Dot Sight DF-M1 has, however, to be announced, Nikon is revealing that it’ll be coming in at $175 (Expected) when it hits shop shelves.
