Low light AF improves with a faster lens. Canon 50mm lens has a bright f/1.8 aperture that feeds much more light to the AF sensors and lets you use quicker shutter speeds, so it locks focus more reliably on dim scenes and moving subjects. The STM drive is quiet and accurate.
Drawback is a tighter field of view for wide star fields and some corner aberrations, but as a budget upgrade it markedly improves low light focusing and image quality.
My go-to exit is weaponizing chores. I smile and say I've got to swap the laundry or the toddler will start free-styling outfits & but this was nice. Or I drop the work line, I've got a call in five, and start backing away. Works way better if your feet are already moving.
