I have the fisheye and its very good. Great fun. I use RawTherapee to edit and I have a lens profile for it so I can remove the fisheye effect if i fancy too so its double versatile
Great buy but if the fish eye body cap lens was at this price, I'd purchase this.
Couldn't resist. Something to experiment with. Reviews aren't too bad considering it's price. Good find.

Thanks. It's £29 delivered (white or silver) from their EBay store. Went for the silver as something fun for a little Panasonic GF5 I picked up earlier in the week.
