You know, I have to agree with Wheatfield on this.
I guess there's a proportion of you guys who like to speculate and whine, some haven't even got a K-5 and yet are bitching about supposed issues that they haven't even encountered first hand but merely read here on the forums. Well all I can say is if it makes any of you so unhappy or bummed out that it deters you from making a buying decision, then don't buy the K-5. Just keep using your obsolete and discontinued or existing Pentax camera or better still jump ship. Why lose sleep and suffer angst over a mere camera? For every disgruntled Pentax whiner on the internet who threatens to pull the trigger towards other brands, there are a horde of new users who truly love their new Pentax cameras.
Thanks to my stellar local agent, I was one of the earliest to get my K-5 in the world and yes I had a sensor stain but that aside, I never fretted or felt flustered but trust that my local agent would work things out with Pentax Japan. I got my replacement from Japan a day or two before the New Year and I have never been happier. Clean sensor, can't find a focusing issue, and there are plenty of other K-5 who I know who are pleased as punch with their cameras. And trust me, we got plenty of K-5 users in Singapore, so much so that our local agent can't even get enough stock to the local photo stores. Locally, I'm still amazed at the number of new Pentax users in Singapore, so rather than an all doom and gloom outlook for some of you, it is bright and sunny over here...
