Question about Rollei C6i

I think that all tripod screw sizes are in the same range, so there shouldn't be any problems. Personally I use the Panasonic Lumix G5 with no worries with this tripod, it's a plate that you screw into the camera which makes attaching to the tripod very practical, it's not necessary to screw for a long time into the camera every time you want to use the tripod. But to be 100% sure you should look at the data sheets of both products in relation to the size of the thread and the screw.
