Learn Turkish: Berraklık açısından kusursuz olanlar, diğerlerinden pahalıdır. - Those that are flawless in terms of clarity are more expensive than the others.

It is built from the noun açı (angle, perspective or point of view). It takes the third-person possessive suffix -sı, the buffer -n-, and the ablative suffix -dan (from). When placed after a bare noun like berraklık, it forms a compound literally meaning "from the angle of clarity".

How does olanlar translate to "those that are" in this context?

Olan is the subject participle of olmak (to be), acting as an adjective that means "that is" or "the one being". By attaching the plural suffix -lar, it acts as a standalone noun meaning "the ones that are" or "those that are". Thus, kusursuz olanlar means "the ones that are flawless".

The English translation says "more expensive", but there is no daha in the Turkish sentence. Why is that?

In Turkish, the ablative case (-den/-dan) attached to the object of comparison is often enough to establish a comparative meaning. Diğerlerinden literally means "from the others" or "than the others". Adding daha (diğerlerinden daha pahalıdır) is perfectly fine, but it is optional when the "than" part is already explicitly stated.
