Since I bought my E-500, I had been dreaming of a fisheye lens. But until now, I still cannot afford one. What I like about the fisheye lens are the effect of the round distortion and it can cover super ultra wide angle of sight. These 2 effects really attract me to fisheye lens.
Since I cannot afford one, I been searching around internet for method of D.I.Y. fisheye lens. After looking through 2-3 sites to get some idea on how to make my own fisheye lens project, I successfully made one myself.
