When my son saw a picture of classroom in my article The Days in Henan, he thought that I took the picture of the classroom by using a fisheye lens.

He said that he would like to have a fisheye lens for his camera. I told him that it was expensive that I could not pay for it.

Last Sunday after our worship service in Bedok Lutheran Church, we took our meals at the market. After that, we went window-shopping. He then came out an idea that he could use a door viewer instead of a fisheye lens. We then went to a shop and bought an EXTRASCOPE PLUS.

That afternoon he tried to use the door viewer as a fish eye to take pictures. We spent about forty minutes looking for our targets and he was happy with his idea.
