The first shot is from the 28mm wide open I believe it is about a 2:1 reproduction ratio meaning that the image on my sensor is 2x the size of the object in real life.
This is a shot with my Sigma 17-70 at about 1:3 it works great as a macro lens but the working distance is almost touching the front element at really close focus which makes lighting hard. It will go to 1:2.3.
These were taken in a south facing window on a hazy saturday afternoon. I could get a deeper depth of field but it would take stopping down more and that entailed shutter speeds too slow for handholding. I will probably end up needing a Macro Rail should I get more into this.
This is closest focus with the K 28mm @ f5.6 ish (Can't remember) the slightest shake makes for motion blur. Definitely a case for using a tripod.
Back to the 50mm @ f8
This is from my 50mm stopped down a little, it has an impossibly thin depth of field wide open. It is close to 1:1.

What on EARTH is a reversing ring, Lloyd? Is it some kind of macro attachment? Interesting. . . Cindy
Cindy,
Look here, this is what I bought: http://www.adorama.com/MCRRPX52.html?searchinfo=reversing+ring+pentax
It is a gadget that screws into the filter threads of a lens that allows you to mount it with the front element facing the camera and the rear element facing front. i.e. reversed. Which allows for greater magnification.
