I will use it mainly with my A50/1.4 lens.
Hi Luben, I've owned a lot of Pentax and compatible TC over the years and if I were to buy just one from the lot that I've owned it would be the Pentax 1.7AF TC, next choice would be the Pentax 1.4X-S TC. In my opionion most early Pentax and non- Pentax teleconvertors really aren't worth wasting time with, they often lower contrast significantly and introduce aberrations such as CA towards the edges of the frame.
