Hi, its probably been covered, but anyone chip in with an oldish cheap fisheye lens or semi.... funds a little low but for three shots could do with some old glass, dont want a full circle fisheye look just a slight wave bend to make some shots wide/but slightly distorted?? steve

The first one is what you are asking for and the second is going to be more of a real fisheye with 180 degrees coverage

Cheers Spiros. thanks

Also check out the Rokinon/Bower/Vivitar/Samyang 8mm fisheye (it's the same lens sold under several different labels).

It's not old, but still quite cheap.

Thanks John
