However, I can exclude tha trick with "establish reputation and then lower the
quality". If some scopes from China can be called semi-apo, while they are
plain achromats (Mergrez) or they can use such methods of color correction
"improvement" as internal aperture stop, then it is difficult to exclude
objective design change in worser side.

Must be read as "However, I CAN'T exclude a trick"
