I doubt it, as the R2A is thinner than the R-D1. I have the grip and the R-D1 and will try it in the next day or two (i won't be home till late tonight). In terms of having a grip on the R-D1, I have a half case with the grip built into the case and it is pretty nice, although depending on the size of your hands it can start to feel a little bulky. Whenever I go back to my bessa I realize how small that thing really is.
