I found this forum a couple years ago when I was looking for information on the K10d / K100d cameras. I ended up buying the K100d. I have used primarily pentax equipment since the early 80's starting with the K1000. I also have and use the me super, the sf10, the zx-50, a ricoh kr10, and another that I can't remember. Just recently I was able to purchase a k2000 from a starving college student at a good price. I like taking images of nature, creatures, macro, etc.
Lately I have been spending some time with a tamron adaptall 80-250mm f3.8 lens. I have some images from this lens on my flickr page:

I also like the vivitar 100mm 1:1 that I picked up a while ago, and I look forward to using the tamron sp 90mm macro that I just acquired.
