Nikon 1 J5 Key facts
Image sensor and processing
With a megapixel count of 20.8, the 1 J5 outstrips all other 1 series cameras to date, and the image sensor is backed up by a new EXPEED 5A processor. Autofocus and metering are carried out via the image sensor.
The hybrid autofocus system is fast and competent. Contrast-detection AF is split into 171 focus areas, and the central 105 areas also support sensor-based phase-detection AF. The camera decides how to combine contrast or phase detection, depending on shooting conditions.
The maximum burst rate of 60 frames per second is phenomenal. It’s a shame that the buffer depth of 20 shots in either RAW or JPEG quality modes means that you can only shoot for a third of a second. Other continuous drive rates of 10, 20 and 30 frames per second are also available.
Metering is based on information gathered from the main image sensor. As with autofocus, the lack of a conventional reflex mirror precludes having a separate metering module, as fitted to D-SLRs. Metering is largely accurate and ‘matrix’ mode generally gives balanced images.
The J5 is slim and light, but feels a little plasticky in places (especially the covers for the battery compartment and HDMI/ USB connection ports). The microSD/HC/ XC cards are similarly fragile. However, the controls have a good, solid feel and the textured covering enables a firm grip.
Need to know
Despite the potential for high-speed continuous shooting, the speed between successive shots in Single drive mode is slow. In our tests, the camera locked us out for about two seconds between shots, in JPEG quality mode as well as in RAW and RAW + JPEG modes.
