Title: Measuring Canon Lens Focus Micro-Adjustment
Post by: Gregory on December 16, 2007, 08:29:16 pm
I have a Mark III with Lens Focus Micro-Adjustment functionality.

how do I test and measure the adjustment required for each of my lenses? I do a lot of photography where the DoF is only millimetres deep so perfect focus (wysiwyg) is an absolute necessity.
