Yep....That's it! I guess I have always had the e-Front Curtain shutter on and only heard one click. Should I turn it off? Is that how all the cool kids shoot?

Cory, for shutter speeds faster than 1/1000 EFCS affects the bokeh in a negative way. Other than that it’s fine. I’ve started either shooting fully electronic (no bokeh issues but risk of rolling shutter) or full mechanical (no efcs), mainly because I keep forgetting to turn it off when over 1/1000
If you want to keep it simple though just turn it on. I used it on for years
