I received a response from March:
Hi Steve,
Thank you for your interest in our scope.

You are correct. This 4.5-28x52 does assemble a High Master lens system.
Super ED lenses combined with other lenses are assembled in this scope
and it is the same as the High Master lens system.
Below is an article explaining the characteristics of each scope.
You may gain a better understanding of scopes from this article.

4.5-28x52 and 5-42x56 are wide angle designs and very compact compared with other similar magnification scopes.
Therefore in order to reinforce the IQ of the compact scope, the High Master lens system is assembled.
High Master lens system is to explain what kind of lens we use.
It is true that 4.5-28x52 has the best IQ among our mid class FFP scopes
but some people may assume that a scope with a High master lens system has the same IQ compared even with our other large class High master scopes.
For scopes(4.5-28x52 wide angle and 5-42x56 wide angle) we used a High Master lens system in order to reinforce IQ,
I changed the wording to Super ED lenses in the product page in order to clear misunderstandings.
But now that I understand that it has led to misunderstanding as well, I have added the High Master lens system on our website.
I apologize for the confusion. Scope will be engraved with a High Master logo.
Our normal build time is about 1 month and it will be shipped.
Please let me know if you have any other questions.
Thank you!
Kindest regards,
Mari Morita
