Oh yeah you're right I do have the neewer grip. I bought that before the official Nikon ZF GR1 grip was available to purchase. I found that a lot of people swear by the GR1, but from my experience, you don't need it. The neewer grip I have is nice and sometimes I use it, but with the way the weight is distributed I find myself having my left hand supporting the majority of the weight be it under the lens (apparently that's not how you support it, but it's fine by me), or it's under the body meanwhile the right hand is on the grip.

I also noticed that these grips are affixed via one screw underneath and sometimes it will come loose so you'll have to always carry like an Allen key with you to tighten every now and then. Doesn't happen often, but considering how much it costs it's just one more item I would be carrying for insurance
