honestly one thing I didn't never pay attention to was the battery grip I always told myself that if I ever can purchase the 90D brand new I was going to kit it out. Never really had a full camera that was kitted out I just used the camera as it was but come to find out the battery grip was very helpful it takes two batteries hey with two batteries in the 90D I can shoot all day The downside is is the one memory card but that's not really a downside when you got a USH 2 The UHS 2 works lightning fast for the 90D. I've pulled at least 135 frames per second after 90D in high speed continuous shooting I don't know where 10 frames per second come from but that's not what I got on a clean memory card
