How Do You Test a New Lens?

I don't know, Brant. That flag looks awfully blurry… Are you sure it's not a decentered element?

How'd I miss that!!!

I think it is a Image Stabilization problem. I would keep the lens and if it bothers him he can send it to Canon and tell them the IS isn't working.

And it doesn't even have an IS ON/OFF switch.....what is this, an EF-M lens???

It's going back....
