My first Pentax was a '70's K1000 screwmount on "loan" from my grandfather. "Loan" turned into a "gift" after he saw the first few rolls of film. And so, a monster was created! My second Pentax was another secondhand K1000, but this time I moved up to a bayonet mount! I admit to having let my interest in photography slip to the point where I settled for a point-and-shoot until I splurged on the *istDL. The DL served faithfully until I found the K20 at a price too good to resist. The monster was reborn, and lives still! Then, I discovered the joys of the digital darkroom, and now it's a tossup between which is more fun - going places to take the pictures or running home to view them and give them a few "tweaks".
Pentax K20D, 18-50 kit lens; Tamron 70-300, and Pentax 10-17 fisheye, which is my current favorite. There are also a lot of odds and ends of "rescued" lenses that I can't bear to part with.
