Which adapter alternative?

Hello, I wanted to ask you, where Tc Autofocus, can replace the Pentax-F 1.7x AF?

The focal length, or better the multiplication factor is not a problem, okay 1.4 x 1.8 x as a

The important thing is that it provides usable images.
Image quality.


Ps.: Sorry for my bad English
