Screw-on-Fisheye attachment lens

I realised that at the moment there's no way I can afford a 10-17mm Fisheye

So (even having read how bad they are...) I bought myself a 50 screw-on type affair...

Here is something I've noticed for those who may be considering....

Wide open (f3.5 on kit-lens) the edges are VERY soft... but at f11 (actually from f8) the results are fairly promising

For a 'just a bit of fun' cheap alternative (while I save!!) to a real fisheye lens its really not that bad!

could you post some samples? I used to use one of these on my canon P&S and it was fun to play with. in the pentax mount, some cheaper but good options are the zenitar 16mm f2.8 and the Rokinon FE8M-P 8mm F3.5 Fisheye Lens for Pentax. The latter I think is available in other brands like samyang and a couple others I believe.

Samyang makes the 8/3.5 and it's rebadged as Rokinon, Vivitar (I think) and others. It ain't that cheap but it's apparently a good performer. The Zenitar is pretty fishy on FF but only moderately so on an APS-C dSLR, with the same characteristics as the DA10-17 @16 but 1.3 stops faster. All of these are frame-filling rather than full-circle fisheyes. Then there's the 12/8 badged as Vemar and others, which on FF is full circle but not 180 (with it circular lens hood) and on APS-C is frame-filling and pretty damn fishy.

For full-circle, I can't recommend anything modern 'cause I just don't know enough about what's available, but I do have fun with an old Kenko 180 Degree FE adapter. Mounted on an 18-55 or 28-80 @ ~40, I get a full circle on an APS-C frame. But for anything like edge sharpness, I need an aperture of around f/40. Slow and steady...
