Very interesting and perplexing, the mount height can't change, it's the most critical dimension, all they can do is to add clearance to the angled area above the mount. Potentially Sigma have had various mounts as variations along production of certain lenses. I know that they have pretty good records as I enquired about re-flashing one of my Sigma lenses and it fell outside the serial range where that was possible for that model
Cheers,

That minute gap will also create focus consistency errors across the frame, particularly in the case of wide angle lenses. That's my concern, not so much the sealing issue.

LOL, plainly you're not an engineer ;)

I'm quite serious, no doubt after the first lot of modified lenses come back from Sigma there will be a chorus of cries about how repaired lenses don't focus properly any longer plus I simply can't afford to have half my lenses away being modified as a working photographer.
The body mod would be quite easy and safe for anyone who knows what they are doing (much less chance of damage than putting WR bodies under running water for instance), I certainly wouldn't recommend doing it that way but it suits me.
I promise to post pictures.

It's a crock anyway, they have screwed up in the past. The first Pentax body to implement that hideous prism overhang was the K10D from recollection.
That lovely bit of jutting plastic wouldn't allow the A*200/4 macro to rotate to portrait mode whilst the pair was mounted on the supplied tripod mount as the set screws on the mount collar collided with the prism overhang, they didn't offer to fix that. It also made using the aperture ring less than comfortable.

It only needs to be a similar size to the mystery cutout above where the Sigma lenses rub, no great drama.

I can see myself loading it into a press with a nice cutt-off disc and producing a neat little scalloped cutout much like the mystery one above. A good vac and a little touch-up paint and she'd be as good as new, just better.

Lenses I generally keep, cameras I don't, so it's the camera that gets modified for me.

I don't believe that anyone is forcing anyone else to participate in this thread.

LOL, for sure, I'm in the same boat, I have a lot of capital locked up in K mount lenses and even the thought of the process of swapping leaves me a little sick in the stomach. I'm shooting professionally and it's a very difficult thing to be doing running Pentax K-mount, I love the Pentax philosophy and ergonomics but I won't support their obvious blunders. Nikon has some great product still and significant support in the amateur and professional community.

Indeed, if I finally end up switching brands after 30+ years of continuous Pentax use it will be to Nikon and I will buy mostly Sigma glass. The body is simply a mirror-box and sensor for my lenses.

Modern, IOW fast silent AF and in the case of the K1, for optimum performance, discount any lenses that don't adequately cover the FF image circle, not many left to choose from then.

Indeed, and the agreement is so good that we can't buy most modern Tamron lenses in K-mount and pay a hefty premium for the equivalent rebadged Pentax version.

Phrase it however you like but if Pentax modifies it's mount in order to exclude previously perfectly usable third party lenses, lots of people will dump Pentax and run, they shouldn't be so smug.

That's what Dremels are for. I have 4 of the lenses on this list, and the total to replace them with equivalent Pentax kit would be well over $10k, much cheaper to modify the camera. The fact that they or their beta testers didn't test/discover this over the years of development is baffling to say the least. If they want good uptake of the camera make it compatible with the main lenses on the market.
