This review does not affect all cameras, so check

The shipment was carried out swiftly from England via New Harbour Sales. The packaging is commendable - in addition waterproof antistatic film - and then the usual Amazon carton. There is a faux leather quiver and a cleaning cloth to do so. Rear cover and front protection cover included.
The lenses are made of glass and the metal housing, the threads properly. Unless: Everything OK

Important:
Explanations for use: My camera records in 16: 9 Full HD AVCHD on. (Widescreen)
It may be that, therefore, on a 4: 3 or 3: 2 camera, the result is better. I can not judge because I have no other camera with 37mm connector.

Preparation !! Important, otherwise the are only nothing ..

You have the camera in the menu item "Camera / microphone" first scroll down to the "converter lenses" appears. Here you will then 'wide angle lens' a. The Camera must know nachzuführen to focus.
Once you did, then comes the first surprise:

Attaching the wide converter / benefits
Although you can unscrew the macro conversion lens, it is not only possible to use the wide-angle attachment alone,
because only the close-up lens fits into the internal thread of the camera. Since the Weitwinkelvorsatz but has a male thread, it fits only together with the compensation lens. (It has the camera actually the Menu "Wide Converter". Annoying.)
What now is, who can understand, I do not understand. It makes sense would have been to hold both threads equal to cover 3 ways. So stay only 2 options. 1. Only macro lens and macro lens 2 and Wide.
The intermediate ring corrected well what the camera actually can itself ...

And now the result based on a 16: 9 video - photo-user -> please looking at other reviews here

+ Extreme macro shots go quite well (but were previously already good)
+ If you have slightly zooms actually a slightly expanded field

0 The benefit is relatively low, since the fisheye look zoomed out the edges of intent in the video are fully visible

- The quality of the video image suffers greatly, you zoom the lens in front, are light sources to 4-stars despite precise focus.
- You have so much zoom in that these blur the advantage Wide effect makes right the first push to naught.
- The line distortion was indeed to be expected but is almost unacceptable.
- The entire image is vague and blurred.
- Fogging the lenses inside ... well ... then it says - unscrew brush and let it cool

Also, we should from now schedule recordings. So turn until everything you want to have the wide angle. The unscrewing my sun visor and the placement of that lens I do then only 1x in the best case. Also you must remove the menu of the camera's wide-angle again. Most me has repelled the total of significant uncertainty.

Rating
At the end I asked myself, I keep the lens? Yes or no. The answer is:
Yes, because the price of 11,11 Euro is almost pocket money, I would have bought blindly at the flea market.
Yes, because extreme macro shots are perfectly acceptable.
Yes, because I have no desire to return, (congratulations!)

The Stars,
There are only 2 stars because of the inflexible gland, the blur despite exact setting on the camera, and the only slightly usable range because the lens is visible as long as the video until the zooming already corresponds to almost the original image.

Now yet conclusively again to note that there may indeed be better on a photo camera, but it remains a blur that is unacceptable because I'm sure.

Thus, it remains at 2 stars by pointing out that the original Sony wide-angle 199, - Euro MSRP costs according to the website.
So there is a quite cheap gimmicks left with much Schrauberei without real benefit. A benefit occurs to me: trashy fun videos?
I have to say that the original lens from Sony is also much flatter and outside the overall diameter greater.
So buy again ... No I would not, not even the other in price by 50, - Euro, because they look like and I can not imagine that they are better (long assembly counterclockwise expensive original)
Actually, it would be 1 star but as mentioned .. for experimentation and for the price there are 2 stars.
