The Sony RX10 has the same 20mp sensor as the Sony RX100 II that is well thought of and it has an equivalent 24-200mm f2.8 Zeiss lens. Having a package that includes the equivalent of a 24-70mm f2.8 and 70-200mm f2.8 makes the $1200 price easier to take.

$1200 RX10


$1000 GX7
$1300 12-35mm f2.8
$1500 35-100mm f2.8

You can't change the lens on the RX10, but a lot of m4/3 people would be quite happy, I think, even if all they had were the 12-35mm and 35-100mm for their m4/3 camera.

I have read that the zoom-by-wire is poor because turning the zoom ring causes the focal length to change very slowly. Maybe that can be fixed in firmware? Still, this looks to be a very interesting camera. It isn't very small, but I can imagine that for some people this could be enticing. More dof, of course, than FF or APS-C and slightly more than m4/3, but that isn't a big deal for everyone.

I could see that some people might have an m4/3 body to use with a couple of fast single focal length lenses and the RX10 instead of buying the expensive 12-35mm and 35-100mm lenses.

Need to be careful with that equivalence. For exposure f2.8 is f2.8 so it is just as fast as a FF f2.8. In terms of light gathering (and effect on noise) and Depth of field though a 1" sensor is a stop slower than m4/3 and 3 stops slower than FF. So in those terms it is 24-200 f8.

My 25f1.4 gives me the equivalent of f2.8 for the occasions when I want shallow DOF. The RX10 would need to be f1.0 at least at the wide end to achieve the same.

It is a very useful and compelling range of focal lengths I have to agree but I do like to go a bit wider than 24mm and 200mm is often not enough reach for wildlife. The wider the range of focal lengths the more compromises the lens designer has to make so I think it best to have an interchangeable lens system.

The RX100 was more compelling because it does what no m4/3 camera can do, and that is to fit in most of my pockets (even in a case) Even the GM1 can't quite manage that with a lens attached.
