The focus adjustment is +8 on my copy. It focuses very quickly and accurately, and is a joy on the K1 II.
The minimum focus distance of 2m makes for a reasonable long macro.
The only negatives are it's weight, the lens focus buttons have to be avoided, it is prone to vibration and shutter shock (better on the K1 II). In very low light something faster would be nice.
My Sigma 500 f4.5 sits forlorn in the corner.

I used this extensively with the DA*300, not at all with other lenses.
There is very little image degradation with the TC. It is sharp, and doesn't hinder focus as long as there is enough light. 420mm is a very nice length.
I ran into three things that were negative.
The bokeh in some situations, for example lowish light busy background is very unpleasant. Hard and confused. The DA*300 can produce this on rare occasions, but the TC made it worse.
The metering is a stop difference, but the effects of light drop off are a bit more extreme. I ran into blotchy contrasty shots in less than optimum conditions. It needs lots of light.
For some reason it seemed to severely exacerbate shutter vibration. I had to use quite a bit higher shutter speeds for handheld. This hasn't been a common issue, so it may be the body lens combination, but it was over two K-3's and two copies of the DA*300. Again, if there is adequate light this is less of an issue. Unfortunately where I live there is often not adequate light.
