Don't get me wrong Ben, The problem exists, and I think Pentax will fix it. I don't think it is all the problem some make it out to be. Nearly everyone I know shooting with a K10D has never come across it, and those that have seen it have only experienced it on a handful of occasions. I think the few instances that it happens get so much "air time" it makes the problem appear much worse than it really is. If you do an internet search for banding with Nikon's D200 you will find just as many complaining about similar problems, even after Nikon's firmware update. I also think the Pentax issue gets more attention because it is considered a "challenger" to these other cameras, and when you challenge the leaders you have to pretty much be better in every way in order to gain any acceptance from the "Pros". I know Pentax is taking this seriously, I have spoken with a couple of people at Pentax and they are concerned with fixing it, but keep in mind like any big corporation they aren't going to gather every employee in the company together and update them on every problem and their progress fixing it, so I'm sure some of the customer service people at Pentax won't be aware of all the aspects of the issue at this time. This camera has been out 4 1/2 months and has had 3 firmware updates, including one that added several new features, I think this speaks highly of the effort Pentax is still putting into this camera, I'm absolutely sure they are furiously working on the problem.
