I use my camera for street shooting and for travel photos.
Before mirrorless, I lugged dslr body with multiple lens and tripod for trips.
Sometime the weight Takes the fun of photography from me. And by end of day I feel dead tired.
As I grew older carry heavy weigh is even more of an issue for me.
So I switch to mirrorless. I find that the image and focusing speed is what I can live with. The selection of lens is quite healthy. I tend to use primes more nowadays making the setup even smaller. The most important is the weight reduction. I can also carry smaller tripod due to the smaller and lighter setup. Shooting becomes fun again
