Sigma 400 AF lens

Hello, My name is Duncan Sellars and this is my first time here, not sure if I am doing this correctly.

I have been thinking of buying a Sigma 1.4 tele extender for my Sigma 400 AF lens (not Macro) and am wondering if it is compatible. Any responses will be appreciated.

I am using a K20D now, also still shooting my PZ1P at times. My first Pentax was a K1000 purchased in 1978. Also had, and still have, a couple of ME Supers.

Should work, yup As long as the lens isn't SDM (which it isn't) the TC will work fine.
