Picked up some older Hoya +1, +2, & +4 close-up diopters made in Japan. They are pretty cool and have super tight depth of fields. They screw on to the front of the lens like a filter. The attached pics of a pin cushion are with the +4. 2 pics are at F2 with and without the +4 and same again at F8 (had to fire the flash). Pen cushion and flowers shot with K10D manual settings using a SMC - Pentax-A 1:2 50mm.

1st shots at F2. Not that impressive. You could enlarge both with and without the magnifier and pretty much have the same quality enlargement. Additionally, they were hard to focus hand held. The F8 shots look much better and show a significant improvement when enlarged. The magnifier performs as expected and allows the image to be enlarged significantly more than than the lens without the magnifier. I had no idea needles and straight pins were so knarly...
