Originally posted by Rico om02013 sent back one camera for dust in the viewfinder. The other bodies they sent back I am not sure what the problem they had for sending them back they are so busy supporting anyone who posts something negative about the K-1. It is kind of odd that tom02013 has been a member since March 2016 has made 135 posts and has 106 likes. That must make them the highest liked per post Pentaxforums member and they have already switched to Canon.
Body 1 went back for dust in the view finder and dust stuck to the sensor that could not shift with a blower. It's not that big a deal. I've had similar with a D750 that arrived in a similar manner previously. It happens to every manufacturer.
Body 2 simply had what I consider to be a misaligned focus sensor (described earlier on page 1) - unable to focus DFA* 70-200, unable to focus 24-70 or 150-450 accurately after focus tune. The camera store confirmed and replaced with a third body.
Body 3 had much better focus performance but the issue with the sticking mirror as shown in the video that I provided on page 1. I was shooting a wedding when this occurred, thankfully I have a K3ii backup that has since become my primary.
With respect to commenting on my join date - March, and my likes per post as a community member here. I don't really feel that It's something that I need to defend or loose sleep over.
FWIW - I still shoot Pentax, I have a K3ii with either a 31mm or 77mm permanently welded to the thing and I shoot it daily. It's a great camera. I'm not married to a particular brand, I simply care about creating beatiful images. I do enjoy the Pentax community here who I regularly find to be very kind, helpful, open minded and pragmatic.
The tone of this thread is intended to promote those values (without diminishing your choice to buy a K1) but in the context of assisting others who may have experienced similar quality control issues and giving something back to the community in the form of useful information - PDF's on erratic focus tune, video demonstrating sticking mirror - that may help others get a positive resolution from either Ricoh or their dealer.
I'm not a brand jumper bashing for the sake of it. Put yourself in my shoes, you are shooting a wedding and mirror starts to stick on a body, you would want a resolution.
