I'm looking at purchasing a new camera lens, specifically a Canon 16-35 F4L.
I noticed most shops now are selling it for around $1,346.
What is a reasonable number I should be able to negotiate the price down to? Is aiming for 15% reasonable?

Only managed to get the lens for $1,270 from JB Hi-Fi Elizabeth Street
Break their balls, then come back and report.
