These are really good. It is important to use exactly the right extension, which may vary slightly depending on the version. Getting it wrong will increase purple fringing.

Thanks Lou. That is a very helpful tip.

I have bought one of these (with an offer) and hope to be using for S&S.

I recall someone (was it you?) testing how slight changes in extension can have a big effect on this and the conclusion being as you say: you need to be exact.

Would you have have a link to that thread? I can't seem to find it.

I only made a brief comment about that, in this thread:

In that thread Ray and others mentioned similar experiences with their MM objectives.
