The EF-2537 37mm 0.25x Fisheye Conversion Lens (Black) from Helder provides 0.25x magnification, to any 37mm front-end lens filter thread, for wide-angle shooting. Whether you're shooting creative portraits and landscapes or working in tight indoor spaces, the high definition EF-2537 opens up the scene and allows you to get far more into every frame. Attach the conversion lens to the 37mm filter thread on your lens and start shooting.
Having 0.25x magnification means your focal length will be cut by 75%, widening your camera's field of view to an extreme degree and giving a much wider and distorted perspective.
37mm Rear Lens Mount
Screw this onto the front end of your currently attached lens and the EF-2537 will transform your camera and lens from a standard or telephoto to that of a much wider angle.
