I read a comment by a photographer recently..... the reason why some pro uses 1 - 2 lenses at time is because it will allow them to compose much faster, and when they need to react fast, and instead thinking of chaning lens for this and that scenario, they can focus on shooting instead....
I think some pro only uses just one fix lens, and that's it... so why not??? Just use once single lens.... only thin is to find the range you are comfortable with.
This is true. However if you can switch lens really fast you'll know you can still catch the moment while switching lens. Like reloading a rifle
