I got my System 1 cameras about 5 weeks ago.
What started as a kind of so-so relationship developed over time into a rather positive thing. As with all photographic gear, nothing will fit all purposes - neither will the System 1 be able doing so. The reason, why I started getting into this system was that for me Nikon did some of the basics right - to be able and the potential to build a solid platform over time around the new mount, like the company proved it for more than 60 years for the F-mount. A camera is a collection of hundreds of attributes - ranging from technical data, to size, to weight, to form, to usability, to agitility, to image quality to price to name a few. It is rather seldom possible to assess the overall performance of a complex technical thing in one aspect.
What is the value of a superior sensor technology, if the AF is not able to focus in a certain condition? What is the merit of a perfect AF, if the sensor is incapable? What is the value of a great package, if the speed of turning on, let the phtographer miss 50% of his opportunities? What is the benefit of having the smallest package, but you need 5 spare batteries to survive a single day? It's the package, not the individual components.
As an (extreme) example: It is significantly easier to get a sharp photo with better resolution with a J1 and the AFS 30-110 set at 110mm (equivalent 300mm) and open aperture vs. a D3x and the 70-300mm VR (Same output size). Due to the optical limitations of the 70-300mm VR at 300mm and wide open, the superior sensor of the D3x is not capable to show its benefits vs. the "weaker" CX sensor. The combination of vibrationless exposure (mirror and shutter), a superior VR (due to lighter lens elements to shift around) and an AF which by the way it is constructed can not exhibit font/back-focus by design and the benefit of a small sensor for the lens design (perpendicular rays through micro lenses, no vignetting wide open, almost no distortion, good flare/reflections characteristics) make the overall difference.
Shooting 300mm (equiv) at 1/40sec handheld and getting sharp images is not the exception it is the norm. 1/5 sec with the 10-30mm @ 30mm (80mm equiv) is no problem either.
It is this level of "ease of use" which turned my view of the System 1 cameras around. This interaction of subtle things can not be deducted from data sheets, it won't tell the whole story if you look at some test charts. It is this kind of utility of a complete system which creates an experience, value and makes fun. I've only shot around 5.000 photos in 5 weeks for myself and most of them turned out to be above what I expected.
Will I give up DSLR cameras and F-mount lenses? No. Is the System 1 a great complementary system? Absolutely. Will other mirrorless camera systems loose their ability to take incredible pictures? Heck, no. Can there be choice? I bet.
This camera will not win hearts and mind by data sheets, but by users actually using it. Photos printed in high quality in A4 are excellent. If the source image is excellent, printing in A3 is no problem as well. Pixel peeper will hate the quality of individual pixels, a specialized quality which is irrelevant for the intended audience interested in great photos taken with ease.
Take it easy,
