Asahi Pentax PC-LW407 wide angle fisheye lens adapter.  This has a 46mm thread for attaching to your lens, but I've used it with a 52mm-46mm step down ring which is included in this sale.  The lens is excellent condition and has barely been used.  It comes with both front and back lens caps, instructions, a leatherette finish case and the original box and instruction booklet.

I have used this with the standard Pentax 18-55mm lens.  At the 18mm end you get the classic fisheye vignetting.  This disappears at the 55mm end - I've attached photos showing the results.  Obviously this can be used on any camera that accepts filters using an appropriate step down ring if required.

 

I'm looking for £25 posted.
