What is the absolute best all-around lens to keep glued to my Canon R5? I know the RF 24-70mm f/2.8 is the gold standard according to almost every review online, but it is just so bulky for my upcoming trip to Italy next month. I also looked at the 24-105mm f/4, but I am worried about low light performance since I shoot a lot of street stuff at night. My budget is around 2k, give or take. Is the constant aperture worth the extra weight or should I just suck it up and get the lighter f/4? Im honestly stuck between wanting that pro look and not wanting to break my back walking around all day...
