I'm not exactly sure that I'll ever understand people's need to explain a problem away. I'd certainly be on board with you if I was the only one that ran into the issue, or it was limited to merely three users, but based on the level of activity in this particular K3 forum itself, I'd call the mirror-flapping issue anything but rare. Do you realize we've collected more reports of this issue than the forum has collected serial numbers of owners itself, and double the amount of positive reviews that exist on Amazon for the camera?
Ultimately, it's an issue that effects a wide range of serial numbers. We've likely exhausted the members here with the issue, but that doesn't mean it should be swept under the rug, thought of as a "feature" or ignored by Pentax.
In response to the notion of shooting weddings, Karro brought up the point of missing the shot. This is part of the reason it was an issue for me. What I'm shooting professionally cannot be recreated. If a shot or footage (from time-lapse) is lost, it's gone forever. When a client is relying on your to get that shot, no backup camera is going to help once the moment is gone. If it only happens, on average, every 3000 shutter actuations, you can say all you want that it's "uncommon" and shouldn't matter, but if your paying client ends up being the one to suffer the lost photos, good luck explaining it to them.
But, I also brought up weddings as an example of a quiet atmosphere where the mirror-flapping issue could actually do more than just cause you to lose the shot. I'd hate to think that in the middle of a quiet church, the camera would suddenly become a disruption itself, ruining the moment for the couple, their guests and even the videographer. Not only might you lose the photo, but you could easily become the focus of some pretty angry clients. Weddings, Christenings, Vow Renewals, Corporate Keynote Speeches... any paying gig in front of an audience in a quiet venue would cause me a lot of concern... and could be reason enough not to rely on the K3. Oh, and back to that once every 3000 number again... if you're a busy wedding photographer, it's not unheard of that you'd be shooting 1000 photos a week. Would it be acceptable for you to run into this issue once a month or every two months? That could be a lot of partially-botched weddings.
Yes, maybe professionals shooting weddings are a subset of a subset of K3 owners... but if a camera company is trying to grow its brand and wants a good reputation, having an issue like this crop up with enough reported cases isn't good for them - and that's bad for everyone, including the casual shooter. Look at Fuji as an example with it's light-leak issue. I'm sure XT1 owners who shoot astrophotography are a subset of a subset of Fuji owners, but Fuji still tracked the issue down quickly, addressed it, and repaired the cameras of anyone who had the problem. I tried to research the issue as well to see how many "reports" through forums they had, and I seem to only be able to count up about 50ish.
As stated earlier, we've had at least two reports of people who had the issue that, at least in theory, seemed to lead to other problems. One user had the camera cease to function at all after a mirror-flapping incident. Another had material spewn onto the sensor and into the viewfinder after a mirror-flapping occurrence. Call both anecdotal or coincidental if you want, but given the violent nature of the runaway mirror itself, it's not hard to imagine that it might cause other problems, even if it only happens to you once.
For me, it comes down to reliability. As a professional photographer, if one particularly camera is less reliable than another, I have no choice but to pick the best one for the job. I chose Pentax initially because part of what I do is commercial time-lapse. As a camera with a built-in intervalometer you would assume Pentax wants to be known as a camera maker who produces a body that can accomplish the job. But with the K3, that isn't the case. I'm happy to report that the K5-II and K5-IIs seem to operate flawlessly, and as intended... but that just isn't so with the K3. It's not an over-reaction to state so, as it's clearly a problem.
Last, but not least, inside of this thread we haven't even addressed other reliability issues with the K3. Along the way I had the camera lock up a lot more than any other camera I've ever shot with (by far). I'm talking about lockups without mirror-flapping, just silent, camera-will-not-respond, freezes that required the camera to be turned on and off several times, or the battery to be popped. You can see one of those lockup right in my video in the original post at the beginning of this thread. I also had lockups in the middle of shooting time-lapse, where the camera just stopped shooting, but it actually looked like it still was shooting (in the sense that if you hit the menu button, it would show you the status screen as if all was fine - it wasn't unresponsive, just not shooting anymore). These odd silent lockups occurred across all firmware versions, and happened with both K3s I owned. So, there's an even bigger issue of overall reliability that could be discussed here. Again, maybe not one that occurs ever time you turn the camera on, but one that certainly caused a lot of concern for me, especially in comparison to other bodies that seem to perform much more dependably.
Ultimately, at least in theory, it seems Pentax is trying to address the issue behind the scenes by stating that Japan is working on it. Since they haven't been more transparent or public about it, all I can do is assume it's true. I do hope that's the case - for all of us who want Pentax to continue to make great cameras into the future, and for the subset of the subset of us who really want to use these cameras professionally.
