light but strong with shadows

On my Panasonic FZ 200 screwed (thread of this lens very tired, housing valent) take the edges of the lens at the wide angle into the picture. So you have to zoom into the image to no longer be seen in the corners of the image, the edges of the lens. Here then is lost and the wide-angle effect.

Who would like to show fisheye images with almost circular image sections who finds this intent well.
My light meter in the camera makes no difference with or without lens. The glasses are really bright.

I personally use the lens for a different effect. The background is slightly blurred zoomed faster and thus I can so better make the bokeh. This effect is normally only get with a large sensor and a 50 f1.4. Quite as strong of effect with this lens is not, but it goes in this direction.

The super wide-angle lens is in two parts and consists of a pre-screws Marko lens. The can also solo screw on lens and make Marko pictures. These are indeed strong Markos recorded, the images are still interesting.
That makes this macro lens strongly recorded sense, because it resembles the strong distortion of the wide angle lens. Thus, you have to the whole essay a pretty good Verzeichnungsqualität attest for the low money.
