Revisiting Joesph Holmes' article on lens variability (my head still hurts) got me thinking.
I have neither a) his knowledge, b) his patience or c) a number of 'identical' samples of a lens to compare against one another....so, for a typical user, is there any strightforward set of steps that can be undertaken in order to check that a lens (and I'm thinking tech camera lenses here) performs as expected.
Basically: Does anyone use a specific workflow to test the lens, or is it shoot a brick wall at f8 and then pixel-peep 'til dawn?
