peephole = fisheye

just made this door peephole into a lens attachment...lots of info online about it (more specifics then I have), has some interesting results. Its still hit and miss for me. do a google search and u will find out tons. Generally, if there is a straight line in the foto it will be distorted, things VERY close to the lens, and taking the photo on an angle (up or down) seems to usually produce an interesting image. oh, and circular subjects as well. Anyone else have any info on the peephole? let me know
