Hi guys,

 

I would like to understand how a lens can be tested in preparation for a shoot. I get how you check whether the lens barrel calibration is accurate. However there are so many different charts you can test the symmetry, distortion and other factors with and I would love to know how it is done and what the charts are called for each test.

 

Also I once saw a camera assistant test his lens and he had written -2 -1  0  +1 +2 on a paper which was pinned on a wall. Then his second AC had to point to each of the numbers. Can you tell me what these numbers are for because usually you always test at the widest f-stop, so I guess that was not changed here. 

 

Thank you,

 

Melanie
