Welcome to the forum.
That is a really good lens, hopefully it will give you many great images.
You did not mention which K&F adapter are getting, they make several, but not all of them have the aperture control ring on them. Since that lens does not have an aperture ring, the price for the adapter with the ring (if you want it) is not much more than for the one without the ring.
I am mentioning this so that if the menu does not allow you to change f-stops for that lens - adapter combination (the lens will stay wide open for every shot), it is still possible to get it to work.
Best wishes.
