This Kenko Fish-Eye 180° lens is converted with φ55mm adapter, so that it can be directly mounted onto the front of any lens that has a φ55mm filter-ring.

For example, if you have a Canon Breech-Lock FD 50mm f/1.8, you can screw this Fisheye lens onto the front of the Canon 50mm f/1.8, set the Canon lens to infinite and the aperture at 1.8, and then, set the fisheye lens at 50 on the scale 30 ~ 200 at the bottom of the lens, and then, use the fisheye lens to adjust the aperture size. You then can take pictures with the fisheye lens.

A 50mm lens with this fisheye lens may give you a smaller size of the picture on a full-frame camera, but a 135mm lens with it may give you a full-frame picture on a full-frame camera.

The lens has been just cleaned inside haze. The glasses are clean and clear. There is no fungus, no mold, no haze, no dusts.

It comes with a screw-on front cap and a 55mm screw-on end adapter. No other accessories.

Thanks for watching and shopping.
