Recently, I heard that Pentax and Nikon will soon release the other “compact” interchangeable lens system cameras. Pentax will use 1/2.33″ inch sensor which you generally found in compact cameras, and Nikon will likely to use smaller sensor too, but probably bigger than that and have 2.5x crop factor. For comparison, micro four thirds system has 2x crop factor.
If the rumor is true, I would like the Nikon approach more than Pentax choice. I think 1/2.33″ sensor is too small for my liking. It is hard to get shallow depth of field and image in high ISO will likely to be full of noise. In addition, most compact cameras with this sensor size already has very nice zoom lens with macro capabilities.
But 2.5X crop factor of Nikon is very interesting. Perhaps it will be more successful than micro four thirds system, Samsung NX or Sony NEX system because in those big sensor system, manufacturers can keep reducing the size of the camera, but the lenses are usually still very big, especially zoom lenses. By decreasing image sensor to certain point, the compromise can be reached. The lenses will be smaller, but the image quality is still significantly better than a compact camera.
If the design and performance done right, this new Nikon system will be likely to be the best portable compact interchangeable lens system ever.
UPDATE: Pentax system will be named “Pentax NC-1 camera system” It will be announced in the next few months.Related Post:
