Fisheye lens

I’ve had a few applications where I needed a really wide angle lens, but the Sunex Superfisheye is about the widest angle I’ve ever seen. With 185o this can actually see back behind the camera – well just a little anyway. And at $800 it seems pretty good value too.

When would you use such a lens? Well imagine you want to look at the inside of a tube – perhaps you’re inspecting a telescope - just put this lens at the entrance and there’s no need to scan or rotate.

Yes, there is a significant loss of resolution, so you’ll need a hi-res camera. But since the lens comes with either a Canon or Nikon mount that shouldn’t be too much of a problem.

Judging by the website material, the main users of this lens would seem to be realtors, but there’s no reason it shouldn’t be put to work in a machine vision application.

Now before I go, this Thursday is Thanksgiving here in the US. That means you shouldn't expect any more posts from me until Monday because I'll be sleeping off all my turkey. See you next week.
