have the purpose of better maintenance ordered the thumb grip. He does this job well, but is pressing the point where one considers just, it angled very slightly in the hotshoe, ergo it wobbles. Thus precisely fit -2 points. Have contrast easy-fit sticker stuck with insulation under the hot shoe on the thumb grip. Now wobbles nothing more. In addition, it comes due to the wobbling while keeping slight abrasions on the camera body. This I solved with simple tape. For the purpose of a lack of alternatives I keep the thumb grip and live with the attendant but correctable ailments. One can keep much better in portrait format just with one hand the camera but yet.
