Super alternative for people who want only now and then a little more focal length

I use the prefix on a Pentax K5 DSLR at 18-55 WR lens.
A Fish-eye lens was too expensive for me as a student, to use only this one for a few photos.
The wide attachment of Minadax has of course not these extreme 180 ° angle of view of a fisheye lens, but for most occasions in which the focal length is not sufficient, the perfect accessory!

However, if only the Weitwinkelvorsatz screwed without the macro lens, the camera is no longer sharp. Also manually is no longer a point of focus in short supply.
With screwed macro lens, there are no problems.
If only the macro lens screwed, also can shoot quite acceptable macro photos. The focusing range is this extremely narrow.

I have uploaded some sample images to illustrate.

All in all, I am thoroughly satisfied with the product! Super processed, including storage bag, cleaning cloth and adapter ring.
For little money the perfect compromise!
Would I buy again at any time!
