I have tried with simple magnifying glass, and you can see that it could be useful when you need to take a macro photographs, or to took picture of some text . It is first try, so it might be only better than that. Left picture is normal A780, and right is with magnifying glass. If someone buy those lens from that site it would be nice to post some pictures.
