I have a Pentax 35-105 Macro Zoom lens I bought new, in '85 for $ 375 Canadian. It has been a fantastic lens, IMO.
Robust, reliable, takes very clear shots. I have used it for over 20 years as my prime lens, attached to our 35 mm, K1000.
The macro feature isn't all that much of a close up, but it isn't bad.
I'm looking for a digital slr and the fact that I have this lens, is the big reason why I'm considering Pentax, so I can continue to use it.
