The best part about this is when you go head to head with the unbelievers and are comparing images, either screen or print. The discussion usually starts off with a nonchalant....oh!!….that's nice, or if your lucky.. pretty good, followed by immediate closer scrutiny and even some exif data mining and pixel peeping, all of which is generally followed by...actually, that's very good (and I love this bit)...you must know what your doing...are you a pro ?
At this point you can play the amateur card, and put all the praise on the camera (sort of a reverse "you must have a good camera"). Re-actions are often quite fun to observe.
Our camera club has two other Pentax users, one recently bought my old K5 with a Tamron 18-200, as a backup to their Nikon entry level model, the Nikon is apparently gathering dust now. The other uses a K1. I know two of the state judges that we use are Pentax users, one has the 645.
In our little retail shop in a rural town I sold a few pentax bodies & lenses after putting my old K200 in the window, someone enquired, having a film Pentax and a bag of k mount lenses, and were lamenting the "death" of Pentax.....I pointed they could use their lenses on the K200 and invited them to bring their lenses in a try it. They did, I sent them for a walk down the street with the mysterious digital camera and one of their lenses. Came back...bought it.
Word got around (rural town....its how things work), I had several enquiries from other closet Pentax film users and when I put my K20 in the window, it lasted all of 72 hours and as it walked out the door the person coming in the door was very dis-appointed as they wanted to buy it. Sold them a new one.
Even here, I know of three people with Pentax film kits from family estates. This is probably a market that Pentax could pursue much more aggressively...…(
picture the advert: a young person, sorting through grandpa's old stuff, perhaps in an attic or room, with sunlight filtering through a skylight, and discovering a bag of Pentax stuff...has flashbacks to family days with grandpa/ma taking photos with that camera, filled with fun & laughter. Scene cuts to the modern Pentax K3, KP, K1, whatever, and a voice over saying don't throw away the heritage, just add the new generation to the old and carry on, YOU are that generation...as the old lenses shown in the ad are bolted on). It could be a very powerful advert...and Pentax, its my idea...ya cant use it without negotiation with me.
