Hi @markangeltrueman! Sorry for responding until now, I was on vacation and traveling for 4 weeks. :-)
You are right about the importance of the aperture of your lens, however that will vary depending on what you will be shooting. For example, for landscape photography you will use high f values (like f/16), while for night photography you need very low f values like f/2.8. I might write a different article talking about lenses and how to pick one depending on what you will be photographing. Thanks for the recommendation!
