Thanks to everybody! Your infos are pretty useful..
So.. I'll try to find a TX to k-mount adapter and modify it as SOldBear explained. Otherwise I'll keep using T4 to M42 + M42 to K bayonet maybe trying to disable the pin in order to keep the stop down, as suggested by Nesster.

Thanks for you answer. I only found a T2 to k-mount adapter by Fotodiox.. but T2 is different from T4 because T2 has a screw mount whereas T4 a bayonet mount.
Elsewhere I read this answer:
"There is no T4 Pentax K mount. The K mount did not exist until 1975-76. The T4 lenses pre-dated the K mount. The TX lenses were introduced starting in 1975 and the series included a K-mount. However, there is no Ka mount as the TX series pre-dated the Ka cameras. A TX mount will fit on a T4 lens, however, you will lose one stop and automatic function, which is why the TX was introduced."
I'll keep looking for it otherwise I'll go for a TX to k-mount adapter; I guess it's hard to find, anyway..

Hello everybody!
Here's my issue:
I have a 70's Soligor 135mm f/2.8 whitch has a T4 mount to M42 adapter ring ..
Anyone knows if there is a T4 to k-mount adapter ring? In the web I haven't found it.. Now I use it with a further adapter ring from M42 to k-mount, but like this I only can use it at 2.8..
Anyone can help me? Thanks!
