I had a lens that produced similar issues with varying results, cost me a repair bill for a rebuild and a couple of parts.

Does this mean that whatever the distance you calibrate the results should be the same?

Lighting is relevant, if you are using a lens for landscape I would suggest calibrating in daylight..... the longer wavelengths of tungsten will make a difference. As you are aware so are the issues with slower speeds induced by often lowish lighting indoors. They also suggest working at the distances most used in practice...... so making a macro lens perfect at 15 feet is not the best plan. Pray for a bright cloudy day , with a constant EV.

Gear ... what I need to get the job done , after all you don't see mechanics listing their brand of spanner as a qualification .
