The CX4 brings enhanced image stabilisation and an electronic level to Ricoh’s CX compact cameras

I used the CX4 in a variety of scenes using the auto settings and am pleased with the quality of my images. Auto white balance produces natural tones and the autoexposure is reliable, with exposure compensation at ±2EV available, too.
The CX4 has the same sensor as the CX3, and it handles noise as expected from a ten-million-pixel CMOS sensor, reaching the 20 marker on our resolution charts at ISO 100 with a steady drop off to the 14 marker at ISO 3200. The lowest available ISO is now 100, whereas in the CX3 it was 80. However, any differences in ISO 80 and ISO 100 are barely noticeable.
Following the current trend for improved image stabilisation (IS), the CX4 has a better capacity than the CX3 to shoot sharp images with good resolution in low light. This is because at 3.7EV, the enhanced IS offers three more stops of light so lower sensitivities can be selected for shooting. Using the CX4 image stabilisation I am regularly able to shoot at 1/15sec, which can mean the difference between using ISO 100 rather than ISO 400 in, say, overcast conditions.
There is an array of focus modes including face priority, spot and manual, with a new subject-tracking AF mode. I have tried subject tracking on a few models and have experienced mixed results. The CX4 is no exception, picking up moving subjects well at times, but in more crowded scenes it struggles to keep the focus lock on the subject.
