The EW-4530 30mm HD 0.45x Wide Angle Conversion Lens from Helder provides 0.45x magnification to any 30mm lens, for wide-angle shooting. Whether you're shooting landscapes or working in tight spaces the EW-4530 opens up the scene and allows you to get more into your frame. Attach the conversion lens to the 30mm front thread on your lens and start shooting. You can even attach 43mm filters onto the front lens mount for added protection and image quality.
0.45x Magnification
Having 0.45x magnification means your focal length will be cut nearly in half, widening your camera's field of view and giving a much wider perspective.
30mm Rear Lens Mount
Screw this onto the front end of your currently attached lens and the EW-4530 will transform your camera and lens from a standard or telephoto to that of a much wider angle.
43mm Front Filter Thread
Add any 43mm filters to this conversion lens for increased protection and creative effects.
