What is it ? The so-called "one inch" or Nikon CX imager size measures 8.8x13.2mm, with a diagonal of 15.9mm. It is the next size down from M43 with about half the area of a M43 sensor. For some reason unknown to me this size uses a 2:3 aspect ratio which I find a bit puzzling as the 3:4 ratio used by M43 and most of the smaller sensors, makes better use of the available image circle.
Cameras The two most notable camera types to use this sensor size are the Sony RX100 fixed zoom lens compact and the Nikon 1 System cameras with interchangeable lenses.
The Sony RX100 arrived to great fanfare last year with some excited previewers claiming it would be the most important camera of the century etc, etc....... Once users got their hands on it some deficiencies in ergonomics became evident. However it still remains a landmark camera because of the high pixel count (20 mpx) and image quality which Sony managed to extract from such a small sensor. The DXO Mark score is 66 which is the same as the Canon EOS 60D and 7D both of which have less pixels on the much larger APS-C sensor size. I rate a DXO Mark score of 66 as indicating good enough image quality for a wide range of users, uses and photographic challenges.
Nikon introduced it's strangely named "1" system to a distinctly unimpressed cadre of camera reviewers in 2011. One photo magazine editor described the V1 as a "mongrel". There were many problems with the first round of 1 system cameras. I think the fundamental one was that the product development people at Nikon appeared to be uncertain as to the target buyer. Was the 1 system for snapshooters, snapshooter upgraders, expert/enthusiasts or gadget /gimmick lovers ? The V1 and it's siblings featured atrocious ergonomics, making one wonder what planet the 1 series designers had been living on while the rest of Nikons' enterprise rolled out millions of DSLR's with mostly decent ergonomic capability (with a few notable glitches). The V2 is a complete redesign of the 1- system -with- EVF concept featuring improved but still not excellent ergonomics. Unfortunately image quality as measured by DXO Mark anyway, has gone backwards, from 54 to 50.
Development potential I think this format has considerable development potential. I rate it as the smallest practical sensor around which a fully featured interchangeable lens system can be built and the largest practical sensor which can be accommodated by a compact camera with inbuilt viewfinder and zoom lens of useful aperture and range. The second proposition is almost proved by the Sony RX100, although this camera lacks an EVF.
To test the first proposition I made a wooden mockup camera with exactly the same dimensions, WidthxHeightxDepth, as the V2. You can see the photos of this mockup at the top of this article. This mockup features a fully ergonomic handle and control interface design, with all the hard controls you would expect to find on a full featured pro level DSLR. It is very comfortable to hold and operate. It has three set and see dials on the top plate with the very efficient quad control system on top of the parallel top handle. There is a JOG lever within easy reach of the right thumb without having to shift grip with the right hand.
The mockup lens shown is about 15mm longer than the actual 10-100mm f4-5.6 1 Series superzoom lens. If this were a real lens I estimate it would be about 10-120mm. This makes an extremely compact all purpose, superzoom one lens kit ready for almost any purpose and ideal for family, travel, holiday or junior soccer. Don't laugh, junior soccer action is very difficult to photograph. There are very few cameras on the market today which can cope with the unpredictable, constantly shifting pace and direction of the player's movements.
When Nikon can source a higher performing sensor for the 1 series and correct the V2's remaining ergonomic deficiencies, I think they will have a very competitive product line. Oh, Yes, realistic pricing would help too.
