My R7 is on order and I am gathering the bits and pieces for when it arrives. I want to get the fastest write speed that the camera can handle.but I dont want to but SD cards taht are beyond the camera's capacity to use. Question 1 ... What is the maximum write speed that the R7 camera can perform at? Question 2 ... The Sony Tough has write speed up to 299MB/s is this too much for the camera to handle? Question 3 .. The Sony Tough cards are thicker than others ... do they fit the R7 without any binding issues. Thanks for your help on this Rob ;
