A bribe? Taking Sigma top managers to some nice resort, perhaps, drink high quality sake, have fun in various ways and then "hey, why are there so few K-mount Sigma lenses?"
That could work, but I'm not sure $100,000 would be enough...
Originally posted by RonHendriks1966 Maybe it is time to upgrade the current K-mount to a full electronic mount called KAF3 (still backward compatible with old lenses). So new lenses don't use the lever for aperture but also do that electronic.
That was my question for CP+, which made into the interview; except that I forgot to explicitly mention the background compatibility assumption.
The answer?
"It’s true that if we were to modernize the mount specifications and removed the legacy linkage we could save a lot of work for lens development and manufacturing. However, compatibility with existing lenses and accessories is as important as our readiness for the future. That’s why we always care about compatibility. We will not suddenly stop compatibility with current products."
They might do it if there's a strong reason for this and can still keep backwards compatibility. I don't think they have plans for that now.

Sorry but Sigma built their own, some decades ago.
