There are no technical limitations for which the K-mount could not compete at least to Nikon F-mount levels.
Okay what's the reason to get a FF when it comes to lenses, smaller DOF right.
you can't make a lens faster then 50mm f/1.2 for the k mount so such a lens for APS-C can never compete with the 85mm f/1.4 on FF for example.
A mount with a bigger opening, smaller register or both solves this issue.
I'm not talking about a mega change, hell they could keep the layout of the mount the same and simply change the register and the size of it, so an adapter would be very easy to make.
Lens register of 30mm and mount opening of... well lets make it big, 55mm that would make lenses possible like
30mm f/0.6
35mm f/0.7
50mm f/1
Or maybe even faster, also zoom lenses with f/2 are in reach.
That's what i mean with making APS-C camera more competitive against FF.
Hell Pentax can keep the K-mount for the FF camera's nothing wrong with that, you can't use APS-C lenses on FF fully anyways so the lost is less great.
The only reason i can think off that they need to keep using the K-mount for ASP-C is that you can use k-mount lenses on it, it's a big reason but i would be happy to move forward if there is a good adapter form the new mount to the K-mount.
actually.... what would you guys think if Pentax, Ricoh and Leica will work together?
Pentax can use the leica M-mount for ASP-C, they need to digitalize the mount and make it work with AF but it would open a new market.
Pentax make the DSLR and EVIL (<budget) Ricoh has said they won't make consumers camera anymore but the have the RCH with the M mount, and Leica make range finders and higher end EVIL
So pentax has the APS-C market and Leica the FF market, if you want pentax FF buy a Leica EVIL or rangefinder is then the answer.
Pentax make the budget lenses, the limited pancake and the DA* type lenses, Leica the high end prime lenses.
50mm f/0.95 Noctilux on a pentax DSLR
21mm f/1.4 Summilux would be great for street photography.
Do we need more reason?
