I'm rather a few wide shots, but then times when I want to make one that I can not usually get enough angle. For these reasons I have decided to use a fisheye. The choice on this Fisheye has fallen, because the depth of field is almost always infinite and thus no autofocus is necessary, the lens has received very good reviews and my rare use would not justify a high price. I have now made some photos and am completely satisfied. The lens is relatively heavy, but compensated with a very sharp and high contrast images. To make a sharp image, it is sufficient to adjust the focus for about two meters (unfortunately no mark) and you're done.
