But Dick valuable

I had already feared, because I bought the teleconverter of the same manufacturer: the thing is determined quite heavy and large. True, but this must be so! As much quality's inside and it takes its place and even has its weight. To use: I use the converter to my Canon G 30, which has been a huge wide angle and now it's just above ground: almost 180Grad angle and (wait for it) without pillows or barrel distortion. Hard to believe, that in the price! Since I take the weight loose in purchasing. Finally, the camera work is more stable, take that into consideration.
Zooming from wide to telephoto without disturbing circle illustration as Fisheye, so frames attitude even in the extreme wide-angle! Everything sharp from wide to telephoto. Clearly it can be quicker to get reflections in the sun, which is optically to be expected, but makes great effects.
Important: Be sure to take the time Aufschrasuben the converter. This part is very precisely made and so man must fit exactly otherwise you dirty the lens thread of your camcorder.

Absolutely highly recommended and quite cheap compared to original converters.
