How does it work anyway? I have 2 theories, either it uses the 60 fps frame rate and some sort of mechanism in the 3D lens to alternate taking a photo from each lens, or it uses the higher resolution of the sensor to simultaneously record left and right lens images on the left and right halves of the sensor (which would explain why you lose digital zooming in 3D mode).
I have a previous version of your camera and the 3D lens. It came as a package with a model number of SDT-750. The lens for yours is upgraded a little, but very similar.
It works very well. If you have any interest in 3D and a TV that will play it, you will enjoy the adapter. Although the displayed picture has a black border and is slightly smaller the effect is as good as 3D Blu-Rays I bought.
Attaching the lens turns the camera into a standard 3D format called "side by side". With my 55" Sony 3D TV and the required glasses, the result is spectacular. Videos taken by my granddaughter of things like the dog running around or her dad on a bicycle are clear, entertaining and very 3D. The best 3D effect is of objects about 10 feet away, although scenery still works.
Uploading the 3D footage to YouTube works too. YouTube can convert it to the form that requires cheap colored glasses.
On a two day trip into Zion National Park, I decided to do the whole thing in 3D. The camera worked fine, but I learned that for scenery, 3D makes you work harder at certain things, especially holding steady. The next time I do a 3D scenic, the camera will not come off a tripod!
Assuming yours came with an instruction manual, read the part on the lens. Although it works very good at adding 3D capabilities, it is an adapter that disables a number of features.
If you get serious about 3D and make it a primary mission, you will need to upgrade to a camcorder were it is built in. You might enjoy reading about 3D here: http://www.avsforum.com/f/192/3d-source-components
