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.



Hi John , while as enthusiasts we will explore further { uwa, long telephotos, fast primes etc} .For many people who shoot at or under 800ISO , which looking through the likes of flickr makes up a huge percentage of photographers. Even though I have an extensive mFT kit and even more extensive FF kit at least 90% of my photos are done at low ISO and between 24-200mm .As a one camera do it all { well do most } i think it looks very interesting


Hi Jim

Yup. I did write that it was a useful and compelling range of focal lengths, so I don't think we have any disagreement about its appeal to the population at large. Henry in his original post was talking about the appeal of this camera to m4/3 users and not the population at large. Its not a shirt pocket camera like the RX100. I can't see any reason why anyone having a small m4/3 camera and a selection of lenses would want or have any need for an RX10. Unless they have a phobia about changing lenses. Its all in one nature does not give it any really significant advantage, but it has several limitations.

  • Smaller sensor, with all that that entails. (Darned good at base ISO though)
  • Fixed range of focal lengths. Thats it - no wider or longer unless you use supplimentary lenses.
  • No opportunity to use a faster/wider aperture
  • You cannot add or upgrade system elements incrementally as you do with a system camera.

There is also the price. I think that most people would have to be pretty serious about photography to stump up that kind of cash. The RX100 wasn't cheap but it is a device that I am happy to carry along with my other kit. The RX10 is small but still too bulky to perform the pocket camera role

I agree that it is an interesting product. If it were not for the price it would be something I would seriously consider buying for one of my Grandchildren.
