If the product has scratches or marks of use on the filter thread, it is best to put the lens aside and look for other models.

Turn the wheels for focus and zoom. All rings should rotate easily and smoothly. If available, check the sliders for switching the focus mode, activating the stabilizer, etc. Shine a flashlight at an angle to the lens and estimate the amount of dust that may have accumulated inside the device. New optics shouldn't have a lot of dust inside the case.
