"Strictly speaking, you actually get three items. One can namely Unscrew the lower part of the lens, thereby obtaining 2 single lenses. So arise 3 combinations. If you use only the lower part, so it acts as a macro lens, both lenses together form the wide-angle capability and one uses only the upper part, so although you get a stronger wide-angle, then with distinct FishEye effect. "
These remarks, I would like to add the following:
By combining the two lenses located (comparison image using SLR converted on small picture format) reduces the focal length of the HDC-SD 909 from 35mm to 22 mm, with exclusive use of the front lens to approximately 10-12mm. In the lens combination a noticeable barrel distortion is visible, but perfectly acceptable. In the upper right and lower corner kick slight shadowing (vignetting) in the max. Wide mode on.
For exclusive use of the front lens, a clear fisheye effect with strong shading of picture corners with max shows. Angle because the adapter used. The vignetting can be reduced by slightly zooming. For special applications to use well.
Highlight of the converter is the macro lens: Impressive the way, Full Frame reproduce small objects, in particular in light push, so that more light is then incident on the lens by the increased distance.
Conclusion: The adapter is the price absolute value, provides useful image quality, however, may be less suitable for "high-end enthusiasts."
