Make your GR III or GR III SE a wide-angle shooter with the GW-4 Wide Angle Conversion Lens. Using this 0.75x lens, you'll get a 21mm lens (equivalent in 35 mm format) to take images and video through. The wide field of view is great if you wanna get more in your frame. Especially if you are planning to vlog with this camera, this accessory is something you should really consider.

Note: Lens adapter GA-1 is required to use this accessory!
