Just received a new Sigma 18-300 lens for my 7D. When zooming, it is a lot stiffer than other zoom lenses I own. How can I determined if I have a problem or if this is normal for this lens? I called B&H and they suggested I use it for a while and see if improves. Need to make the determination within their 30 day return policy.
a. Many things with moving parts are stiff when new, use it a lot for a week or two.
b. B&H sold it, Sigma made it, contact them to ask the question.
