I was talking about the istore. Yes I know you can purchase third party software across platforms.
From what I've read all the manufacturers have Patented their lens mounts. If you have a link that shows that Pentax didn't patent the K-mount or any other preceding mounts then please post it. Pentax files patents for all of its inventions or creations.
Here's a link describing the pentax K-mount patents (Asahi Pentax and Pentax SLR 35mm Cameras 1952-1989
By Danilo Cecchi):
Asahi Pentax and Pentax SLR 35mm Cameras 1952-1989 - Danilo Cecchi - Google Books
Which means if you manufacture the lens mount and put it on a lens you build, it would be unlawful to sell it without obtaining permission in the form of a license from Pentax - which you gotta pay cash-money for.

Microsoft bundled Internet explorer with windows to shut out the third party browser companies.
Or, Microsoft cannot prohibit another software company from creating software to suit Windows, in fact Windows encourages it and facilitates it with freeware. Much like Apple applications, you can make an app and sell or give it away for free for Iphone. If you sell it Apple takes a 30% cut.
But what I meant refers to third party manufacture of any manufactured good. For instance non OEM car parts. The car manufacturers tried to stop third party manufacturers by invalidating a cars warranty if the owner used third party parts - the courts over turned this.
If the manufacturers had their way there'd be no third party anything and we'd get gouged by them. Courts and governments want diversity in the economy.
Regarding lens mounts and pins: Pentax would have patented it, which means you cannot make it without paying for a licence from Pentax. Much like in the communist era, Fiat sold licences to the commies to allow them to make Fiat 500's 124's etc.
I've seen similar debates on Pentax forums about Chinese knockoffs such as the cheap unlicensed battery grips for sale on ebay.

Nice !
But the guy at Sigma who decided to put USB ports on its lenses to facilitate firmware updates may need a tin foil hat too !
I think we're gonna see more USB connectivity on our camera products particularly the third party manufacturers, and perhaps to a lesser extent the body makers.

So I'm thinking that as Pentax and the other camera manufacturers make changes to their firmware - whether to sabotage the third party manufacturers or not - they wind up causing problems for their own products. To which they are liable to correct with firmware updates, but could in fact correct the problems for 3rd party makers.

Yes, so my hypothesis is looking plausible. I have a Sigma flash which works fully on older Pentax models, but on my K-5 it does not remote fire.
I believe that third party manufacturers have a right to manufacture their products only they have to pay licensing for making the mounts/connections, plus the manufacturer need to provide firmware for the lens to communicate with the body. Much like the Microsoft Internet explorer anti-trust case:

Over the years I've read and seen reviews discussing new lenses and flashes. Some third party lenses will sometimes not auto focus properly on occasion, and similarly some flashes will over expose occasionally.
The theme to these glitches are, that 90% of the time the lens works fine, or the flash works well 90% of the time - 1 in 10 there is a fault.
Now seeing how the camera body can read which brand of lens or flash is on the body, I'm suspicious that all the brands will run software or "algorithms" to cause the 1 in 10 faults.
I remember seeing a review by a pro on YouTube where he was reviewing the Sigma 70-200 f/2.8 and 9 times out of ten it focused perfectly, but the tenth it was off. So as a professional he did not recommend it and preferred the Nikon or Canon lens because it works perfectly every time. To me, the camera body is creating the auto focus data, and the lens is the slave and it has no sensor to see with.
The million dollar question:
Do the camera manufacturers build into their camera bodies algorithms to cause glitches, as to sabotage the third party manufacturers and make you buy the original equipment ?
