This review is part of the test of the Nikon V1. Strengths, weaknesses, conclusions and practice shots are recorded in the test of the Nikon V1 and associated lenses for the Nikon 1 Series: Nikon 10-30 mm and the Nikon 30-110 mm . The measurements for this test were performed using Imatest. For the test method and explanation of terms, see FAQ.  Nikon-1-V1

Sensor resolution

The Nikon V1 delivers, both with the Nikon 10-30 mm zoom lens as the Nikon 30-110 mm zoom lens, reasonably good results in terms of resolution. A Jpg file has over all ISO settings in the center a resolution of about 1500 lines per image height on average. At the lowest ISO settings, the resolution of 1800 LW/PH is at the highest to finish at 6400 ISO at about 1300 LW/PH.

With a standard editing of the RAW files in Lightroom, a greater impression of sharpness is obtained, which translates into an average resolution of nearly 2000 lines per image height. By not applying noise reduction to the RAW files, the resolution remains constantly above 1700 LW/PH in this chart.

Dynamic range

The Imatest measured total dynamic range of the sensor is on average nearly 10 stops, both for a RAW file and a jpg file. That is what you would expect for a 12-bit sensor. Much more important is the useful dynamic range. A poor signal/noise ratio in the shadow parts reduces the dynamic range of jpg files to a usable dynamic range of 6 stops at the low ISO settings up to 2 stops at 3200 ISO.

The Jpg files perform, by in-camera noise reduction, seemingly better than the RAW files at all ISO settings. Yet, that is not the case. We test the raw files without using noise reduction. That is how you maintain the highest possible detail in the shots, while the noise (though measurable) is not visible in a print. If you carefully optimize contrast, sharpening and noise reduction of RAW files, it is possible to realize a usable dynamic range for RAW files, which is better than or equal to that of the jpg files.

Noise

Comparison of the noise in jpg files with the measured noise in RAW files without noise reduction shows that a modest noise reduction occurs at all ISO settings at the jpg files.

Nikon has chosen the ISO range for this camera well. We know from experience that if the noise is less than 2.5%, a photo can be printed on A3 + size without the noise being experienced as disturbing.

Below are examples of noise when you would show an unprocessed RAW file without any noise reduction at full size on your screen. By applying noise reduction, it is possible for the RAW files to achieve even better results.

The output for noise of the Nikon V1 are at 6400 ISO a little lower than the measurement results for a RAW file of the Panasonic G3 at 6400 ISO. Visibly, it is difficult to see the difference.

The Nikon V1 offers RAW files with an excellent color reproduction for both RAW files and JPG files (neutral) directly from the camera. The color reproduction is also very consistent across all ISO settings. The green and yellow colors of the jpg files are a little (measurable, but almost invisible) too saturated with the Nikon V1. The average measured saturation of RAW files that are converted in Lightroom is between 105 and 107%.

The picture above shows the color errors of a 100 ISO jpg (neutral) picture taken in daylight. The further the ideal color (square) is removed from the color display of the camera (circle), the greater the color difference. For the test method and explanation of terms, see FAQ

The automatic white balance does its job properly with the Nikon V1. The color deviation is certainly greater than in daylight shots, but these results are very good. In terms of color rendition and white balance, the Nikon V1 belongs to the better cameras.

With Camera Review Stuff I hope to make a modest contribution to the pleasure that you get from photography. By testing cameras and lenses in the same way, evluating the results and weighing up the pros and cons, I hope to help you find the right camera or lens.
