Quote:The lens is very large because the lens designers of the mirrorless companies are less skilled, and the companies perform serious price gouging because the market for the non-kit lenses is mostly wealthier amateur users. They charge such a crazy amount for a mere 300/4 because people will buy it for that.
I assume you have some highly specialist knowledge about lens design to make that statement. However form what I can gather you are Brendan form Lens Rentals - a young 2nd year optical engineering student. No offence intended, but perhaps the more senior designers who work in the industry may have some experience and knowledge which should not be so easily dismissed.
