I am looking at buying a case for my GX1 with 20mm mounted. The official Panasonic case for GX1 is DMW-CG13K. My question is whether a case designed for GF5 (DMW-CG10K) would fit the GX1 as well. Dimensions of each case: DMW-CG13K: (W x H x D) 125 x 95 x 85mm DMW-CG10K: (W x H x D) 130 x 105 x 85mm The dimensions are actually puzzling because the GX1 case is smaller, yet GX1 is larger than GF5: GF5: 107.7 x 66.6 x 36.8 mm GX1: 116.3 x 67.8 x 39.4 mm Has anyone used the case of either camera with the other camera? Any fitment issues? Thank you.
