I already have a 50/1.4 lens and plan to buying a more expensive version of this lens which only just came out and still not available in most parts of the world. Since this is a brand new lens, there is a large online community that is eager to know how these two lens compare. What is a proper way to do lens comparison? What tools would I need? And is it possible to do it at home?
Should I be printing out test charts? If so where? And what about lighting conditions, would it matter? What are some comparison shots I should prepare? Center vs corner and others?
