You would if your kid was playing middle/high school basketball or volleyball.How many of us shoot at those high ISO figures on a regular basis? One moment people are complaining about noise in m43 at 1600 ISO, and the next minute others are happy to use FF at a far higher ISO. What's wrong with using the denoise feature in DxO etc?
High school gyms are DIM, then couple that with a FAST moving sport.
Maybe even outdoor sports.
My local HS plays football, soccer and lacrosse after school, so while the first game is in the late afternoon sun, the 2nd game (usually varsity), is at NIGHT under lights.
No sunny Saturday games, like back when I was in high school.
Swimming and water polo also go into the night under lights.
Baseball, softball and tennis do not have lights, so they have to be played in the sunlight.
If your kid is in the band, the theater is another DIM venue.
But at least you don't have to use a FAST shutter speed like when shooting sports.
If you don't have kids in these sports/music, then the above does not apply.
