Welcome! There are two Pentax 85mm f/1.4 lenses so which one you bought is unknown. It could be the FA*85 f/1.4 as mentioned above or the Pentax-A 85mm f/1.4. Both are exceptional but the A version is manual focus only.
You might want to look into fine tuning the auto-focus on your 24-70, or check for decentering. Most folks seem to find it very good at least as good as other zooms in that price range.
