It seems - and correct me if I'm wrong - that the battery grip for the X-T3 adds 2 extra batteries, a bigger grip and duplicated buttons, but NO extra features. I believe it is sold with 2 genuine batteries. Can anyone confirm this? It is sold in Australia for AU$478 and the batteries sold for AU$132 each, which would make the grip cost $214. So if I just bought 2 batteries, I can have a smaller and lighter body and $214 to put towards another lens. So my question is: Do you think buying the battery grip is worth it or not? Please VOTE, so we can easily see the way the chips fall. Thanks.
