The intent lenses are likely to be used only against a normal lens.

Although I had wondered about the extremely reasonable price, but gave me no particular thoughts. When the package came, I was surprised that it is not self-sufficient lenses, but only to objective intentions in the sense. That should necessarily know and which was not so in the description.
If you have a camera with normal lens simplem who buys here an enormous amount of creativity for comparatively little money. You can all the filters and lens attachments screws before its normal lens and I suspect that will work.
But we have the camera already with two zoom lenses and for this set is not in my opinion be used. First, any conventional zoom has a better message than this intent and secondly, you have the zoom anyway relatively much light loss compared with the normal lens, and if you still screwed before a conversion lens, then it turns not even the Auto Focus.
I could not test with normal lens, because I have none, but I would sometimes tap halfway "green light". For zoom lenses, I would not recommend this set. I returned it and hope everything checks out with the refund.
