I think this is great! I actually joined the Pentax family 1.5 years ago, based purely on its specs, price etc and quickly realized that this is a very 'exclusive' club
I live in Canada and have not seen anyone else with a Pentax on my daily travels (besides my good friend whom I recommended a K5 to), but I was pretty stoked when I was travelling last year, and actually came across someone else with a Pentax camera - twice! Once on a remote island in Thailand (some Malaysian tourist on the boat had a K5), and again at the foot of Mont St Michel in France - a Japanese tourist and his girlfriend. I saw his red on black camera strap, and he saw mine as we passed each other, and we exchanged the universal nod - "good taste in cameras!"
Keep the sightings coming!
