I would search for "Pentax Attachment Lens" or "Pentax Attachment Lens 45-125".

Hi Mark:

I replied to your post, hope this helps. Phil

The Pentax close-up lenses are meant for prime lenses and are not designed for the K45-125/4 zoom.

What you are looking for is a dedicated "attachment lens" labelled 1:4/45~125mm

I don't have one and I've never see one for sale, but I'm sure they exist.

I do have the attachment lenses for my two K85-210 zooms if you want an example.

Great! Yes, Maryland Heights is one of our favorites. Then we walk into Harpers Ferry for some ice cream. Some time I want to go out the Appalachian Trail south of Harpers Ferry. There is apparently an overlook just off the AT, just south of where the Shenadoah and Potomac rivers meet. That would be a good photo op, and it would be fun to go with someone who was a bit more patient about someone stopping to take pics. (My wife is pretty good about it, but it usually means I have to run to catch up!)
I've only been using a DSLR (first was a K-x) for about 4 years, and I've met one other American and a German using Pentax.
Thanks!

Hi Mark, I'm seeing the photos on both computers in all three browsers now.

I live near Shepherdstown, looking forward to a nice sunny comfortable day to hike up Maryland Heights with the DA 10-17 and shoot Harpers Ferry.

Maybe we can get together sometime, in nearly 10 years of shooting Pentax gear, I've only ever seen three other people with Pentax cameras--one is my daughter, one of the others was in Russia!
