I have 2 questions regarding the lens and combo

I have looked at one on and off for many months, but passed on it so far due to 2 problems.

I found CA very bad with the AF TC. Much worse than my 300mm F4 with the same TC, and second, with the PKA adaptors I tried, and the store had 4 of them, I could never go below F4 with the lens.

Is that just due to older PKA adaptors?
