I see the body of the E-M5 III is manufactured from plastic. Does this mean that the non slip finish on the finger and thumb grips are moulded directly into the body or are they separate units which are added later, as in the E-M1 models?

Presumably, if they are moulded directly into the body, it will avoid the problem of them becoming detached with use, as can happen with the E-M1s. On the other hand the textured plastic finish might be as 'grippy' or pleasant to hold as the rubber grips.

Does anyone know which system is used?
