When I speak of "better" I'm referring to value for money, in other words, "bang for my buck" .
One very wise man told me: "if you buy a thing that seldom/ don't use, even it costs you $1 is also consider expensive".
So long you can utilise it fully, how much it cost is no longer an issue.
Whether is this lens you are about to buy is really a "bang for you buck"? Only you have the answer.
