I don't have any opinion about whether Sigma is right to make K-mount products without a license, but I do see a lack of common sense on their part. It appears that Sigma have sold no less than eleven lens models in K-mount that are fatter around the mount than any Pentax made K-mount lens in history. That is just asking for trouble. You would think it would make sense to build your lenses within the size dimensions of the largest Pentax made lens, so that this issue could never occur.
It looks like the prism is set quite far forward on the K-1 compared to other cameras, so I imagine the forward slant was necessary for that and is not some kind of cosmetic flourish. You can't blame Ricoh for not adhering Sigma's lens specifications, which I'm sure were not decided in consultation with Pentax, Ricoh or any other manufacturer. So, it's only right that Sigma takes in upon themselves to fix it, which is what they seem to be doing. I just hope that it ends up easy for users to get their lenses working properly.
Actually, I don't think either side comes off looking bad here, as long as Sigma is proactive in fixing the issue.
