Actually, I have these filters myself and, although everyone says they aren't parfocal, they certainly seem so to me. I have never needed to refocus with mine, despite checking carefully with a Bahtinov mask.

That's good news. What filter wheel do you have Luke?

I have one of these, a Scopteknix. They are the cheapest on the market, and not particularly highly regarded and for only a few quid more you could get a better one, but it does the job.
