Okay, say I am aTom or someone who constantly takes pictures of things that he really doesn't have the right to. Sure, I'd look like a real pervert if I aimed by camera in the neighbor's next door window, but what if I was aiming it at some birds (while still looking at the neighbor's window)?
That is the concept behind Opteka's Right Angle camera. A way to look like you're photographing something else for those who might not be get their picture taken. This special lens is designed only for select Fuji cameras, but if it gets popular, the paparazzi might be shooting in the other direction.
You can get it for about $40, and I don't know if I would suggest getting it.
