Fit Manfrotto N8 fluid head? I have a Canon 5D ...

Fit Manfrotto N8 fluid head? I have a Canon 5D Mark IV with battery grip and 70-200mm f/2.8 II. I need something under the lens ring to raise the camera, so that the battery grip won’t be blocked by the fluid head from moving back-forward. Will this plate help? Thanks.
Asked by: Qiao
It may work. Unfortunately, we cannot test here. My concern is the 577's height of less than an inch is insufficient for what you want to do But I would suggest trying to see if it works. If it does not, I would suggest this riser. There are other risers but they are more expensive and I do not think quite right.

question

Does this hold a Ronin Original Plate?
Asked by: Adrian
Unfortunately not. A very good solution for what you wish to do is using the CineMilled Quick-Switch Mount Plate for DJI Ronin B&H # CICM401. This will allow you to go from the Ronin to the tripod and back again.
