We came across this Tweet in a casual scroll and couldn’t help but wonder… How many of you have tested your lenses right after buying them? We’re betting that most don’t because it’s typically a safe assumption the lens works like it should and like you expect it to. Our friends over at B&H argue that you should test it anyway and they even show you how to test the lens. Check it out!

Now that you know how to test a lens, will you start implementing this into your newly purchased gear checklist?
