Hi,
The lens I am looking to get next; Canon 24-105mm F4 L, seems to have that "quality" issues.
Some people report that while it is a very good lens, there seem to be copies of that lens out on the market that are not as good as they should....as if the internal QC at Canon was letting inferior copies out. IS there a quick and easy way to test a lens? What is your approach in buying lenses in general? Are you concerned with getting a copy that somehow doesn't deliver?
Please help.
I didn't find the right solution from the Internet.
