Since I bought an L plate for my a6000 the problem was how to use it with my tripod since it is not compatible with arca swiss. My choice was either to change the entire head or only change the plate. Clearly the second option was much cheaper so I went ahead with it. I bought an arca swiss plate 38mm from amazon (the same plate comes in different brands eg neewer \ andoer) at a cost of 16 euros. I am very satisfied with the build quality (given the cost) and finally I can use the L plate with my tripod. As we see the head screw is unusual and strongly recommend that use a boss adapter female to male to abut the plate. I personally do not use boss adapter and I have not encountered any problem. The plate has a hole 3/8 "and can use the existing screw Manfrotto. Together with the plate is given and one adapter 3/8" to 1/4 ''. I thought it good to share if someone wants to convert the plate of Manfrotto in arca swiss.
