I purchased this from Amazon US, but a Japanese customer canceled their order, so I am listing it as unused. This is a 0.4x ultra-wide fisheye lens. The 0.4x ultra fisheye lens offers the ultimate fisheye effect and high barrel distortion. It exaggerates depth by pulling nearby objects closer and making distant objects fall into the background. For most cameras, the 0.4x ultra fisheye lens achieves a horizontal field of view of 130° (180° diagonal). With a fisheye, you can capture the ultimate action shots, dramatically and practically. With its near-perfect depth of field and unmistakable style, this lens is a must-have for action sports shooters. It is an essential tool for extreme sports and dramatic action shooters. The fisheye lens has been affectionately nicknamed the "Death Lens." With Opteka's unique integral shade/protector, the Opteka fisheye is known as the "Claw" or "Death Grip."
