The lens I actually served me only for testing and for just under 100 euros one speaks in this case actually a plastic shard. With practice, even good pictures come out. Focus is always relative and I do not think that an image as hard as sharp as the "big" needs to be. I did not really expect much, but get more than expected. Is little light available, you should definitely use a tripod or have ne steady hand. Judging, however, from a sunny day, the colors come out surprisingly well. Although it is almost a meter away at the focusing distance of the object, but macro acts just like macro. (I do not use the macro function actually, because the whole looks the same to me) details are also clearly visible. Among the negative characteristics: it keeps the lens is not fixed, makes it his own business. I knew before and since I'm often on the ground and snapping for me not a big problem. If, sharply with enlargement, there is also the feeling that it would be an earthquake under the camera to go. It reacts to vibrations scary. The one can escape with autofocus or simply screwed times a minute until it thinks is sharp. The version is actually made of metal, which is made of plastic, even at more expensive often!
As I said, I knew beforehand what I anschaffe me there. I had all the negative points known and yet I have it and I will keep it.
Who wants to look simply times the range telephoto photographing without having to set the price equal to one used car on the table, has patience and fun on manual turning to something is sharp, the lens should increase. To practice all awesome.
