<s>[INST] I'm considering buying a new lens for macro photography. I've narrowed my choices down to two options: a 100mm with f/2.8 IS macro lens or a 50mm f/1.4 non-macro lens with extension tubes.

I've read conflicting information and would love some unbiased guidance. Here are my questions:

1. Working distance: Should I prioritize a longer working distance for better lighting, or is the difference between 100mm and 50mm negligible?[/INST]
