Well the photos seem far away that u don't even realise they are shot with a fisheye.. they could have been taken with any lens really.Ian Kachmar said:
But when you go close it makes the distortion much more noticable, and thats the idea of wide agnle lenses.. to gte up close and still manage to get alot into the frame.
So yeh just go closer.. the fifth shot is close enough just you could of composed it alot nicer.
