Originally posted by Uluru However, I think that if an APS-C sensor is used, then a benchmark for size would be Leica X1 & X2. If Ricoh can make it better than Leica, they have a sure winner. Actually, if they make it less clunky, faster in operation and slightly less expensive than Fuji X100(s), and integrate better LCD than Leica (which isn't hard task at all!), they can have the best APS-C compact in the market.
They already do. The GXR 28mm.
So it doesn't make sense in terms of both those cameras you mention being a benchmark that Ricoh can match for size, because they are both actually bigger than the GXR.
The Ricoh GRD on the other is a compact camera even smaller than the GXR. Which means the Leica X1/2 and the Fuji X100 aren't even in the hunt when it comes to competing in camera size.
So nor does it make sense if people think the GRD ought to have the same size sensor as its larger GXR 28mm cousin, because then it wouldn't be a GRD any more - it would be the GXR 28mm. Which they've already got. Why would they make two same cameras? So this is a non-story.
My wager is the GRD will have a 1" sensor. An APSC sensor simply won't fit in a GRD - otherwise Sony would have put one in their RX100 which is similar size, which means that camera has shown a 1" will actually fit in a GRD.
