I don't think, that there will be anything about Pentax FF at Photokina at least this year, maybe next one.

Thank you :)
One really small issue remains: sometimes the smallest aperture i can set is 5-7,1 instead of 4-5,6. After some photos it goes again to 4-5,6. But this is a small issue now :D

Hahaha :D great, now it works :D Thank you a lot :) i had this idea too, but then i didn't believe that it has something to do with it, because there was no hole and this was actually the point :D

Thanks.
I see, so this is just for manual set of the aperture. It works only if the boomerang is down, else aperture can't be closed.
Unfortunally i can't find anything about flashing F with changing numbers, everything i could find is flashing aperture with --.
I tried to move the lens a bit off the camera, that the aperture still has numbers on the lcd, then the flashing stopps and i can set an aperture from 1,8 up to 32, what is wrong, because the lens allows only F4-22. If i make some photos then the aperture stays at open and doesn't change.

thanks for your reply :)
It shouldn't be the spring of the aperture. I post 2 photos. 1 photo with a red circle, i don't know the purpose of this thing.
I think there is something wrong with the contacts, but i don't know which ones, i tried to rub them with a finger, but still no effect. I also don't know how could i damage there something, because i repaired only the mechanical parts.

I can't edit my messages and i have some updates. This would be my updated message, i think now is something wrong with the electronic. My other kit lenses working fine on my K-X.
Hello,
i bought my Tamron on ebay, but didn't see that it has a defective aperture. The problem was that the ring, which has to be rotate to open the aperture was deformed, so the spring was too weak to rotate it back to the close form. I disassembled the first 4 screws and a ball and a small spring were falling out. As i figured later, the ball came from aperture ring it has another bigger spring for pressing. But what i can't figure out is the place where the other small spring came. :(
Now i repaired the metalic ring, so the ring comes back to closed form, but the aperture of the lens still doesn't work :( The aperture now is always closed, but if i use the lens on camera in manual mode(switch button on the camera) it shows F=4 and it blinks to aperture which i set often, but the most photos are made in F=4, somehow i managed to do F=13 and F=14 photos. In the Auto mode there is no blinking, it's always at F=4 and i can't set anything else. I tried it in M and Av modes.
I don't know what i did wrong, because now it should work. Maybe it has something to do with the spring, which i can't identify.
I hope someone can help me.
I added photos of the lens together with the spring.
Dimitri
