Tamron 28-75 question

[Jmurman]

After readng the posts about this lens and seeing the tests, I decided to buy one tonight.

The question I have have is about chromic abberation. How do I test for this?

Thanks!

Take a picture of some tree branches with a bright sky behind it at f2.8.
Sort of like here:
