How can I test to make sure I have a good copy?

Recently, I purchased, and have been using, the DA* 16-50 f/2.8 and seem to be getting good photos when using it.

But!, I want to be sure.

Can someone suggest a simple test that I might do to verify it being a good one?

All response, help, tips, suggestion and answers will be greatly appreciated.

Thanks in advance.

Ed

Hi Ed,

Not sure you've seen this before, but it will look familiar once you do. A friend sent this to me when I was asking him about testing for information about back focus issues. Here's the link.

Good luck.

Thanks, I had not seen it in its entirety. I'll check it out.
