Exactly. Got some lovely ones when they're sitting or doing something slow, but that doesn't happen often.
I had more luck with my full frame, the D610 which is very quick, but it's also a beast and I plan to move it on too. Definitely no need for a full frame in my life.
Albeit that grip...
Actually, speed is definitely a plus. I basically can’t use mine when with the kid unless it’s deliberately blurry/flash combo.
