There's a thread over on CN about these, they were designed specifically for APM and the internal construction is shown.

Focal lengths way too long. Prices look alright though. If they make them in 2-3mm I'm in.

These are not optimised for fast newtonians. Bear in mind the european market which APM cater for is mainly refractors with flatteners, SCT and maksutovs, and Markus Ludes has a 16" mak.

And over small fields typical of eyepieces under 7mm field curvature shouldn't be an issue anyway.

Even with my my maks I could use 50 or 60mm eyepieces.
