Lets find out the fisheye inexpensively. The results are not perfect tjrs, especially when we do not know. For example on my 50mm AC is useless, it's just rotten, while 18-135 is on my nickel, I turn to the macro (I made a very pretty picture of the full moon placing it above my mirror telescope for example). In short, it makes you want to have fun and to invest in the above range to take full advantage of the fisheye effect.
