The Canon 100mm Macro is my favorite walk around lens. I really enjoy the exercise of framing shots with the prime lens. I felt like for me having a medium zoom, 24-105mm like most beginning photographers, I'd become over reliant on changing the focal length without properly evaluating the perspective and framing of the shot.

When I did this shoot

I got frustrated with switching between a wide and relatively long lens and having to clean up dust spots afterwards that I got one of these

which is great for just walking around and I use it for outdoor running events where I can get pretty close and the long end is long enough but the wide end is good useful for crowds

Thing is I sent out my old α7ii body out to be repaired and got a monster backpack

so now I go out with two bodies and even more lenses though I tend to have a cycle of having a heavier and heavier pack until I get an injury, lightening up, healing, and then getting a heavier packer again.

I definitely enjoy prime lenses too, I have more 50mm's that I can rationally explain, also the Sony 90mm macro lens which DxO says is the best lens Sony makes

which is not just good for macro work but also portraits and just random stuff. There is definitely something fun to spending a lot of time with a prime lens and working your perception of space around it. Back when I had a Canon I had just a 20mm full frame lens fitted to an APS-C body.
