The Fujifilm X-T20 and X-T10 are more similar in size than any of the other cameras Fujifilm has refreshed so far this generation. The Haoge Vertical grip below is an inexpensive, yet functional grip for X-T20/10 cameras that I have heard very good things about from X-T20 owners. The Fujifilm X-T20 has also been discounted for the first time $50.
