Samsung EX2F review
Noise, resolution and sensitivity
These images show 72ppi (100% on a computer screen) sections of images of a resolution chart, captured with the lens at its 80mm setting. We show the section of the resolution chart where the camera starts to fail to reproduce the lines separately. The higher the number visible in these images, the better the camera's detail resolution at the specified sensitivity setting.
With a 12.4-million-pixel resolution, it comes as no surprise that the EX2F outresolves its 10-million-pixel predecessor, impressively scoring 28 on our charts all the way to ISO 200. This is a strong performance in the centre of the frame, while at the wide 24mm focal length there is a minor drop off in edge detail due to lens distortion.
It is difficult to extract the best possible detail from the raw files using the company's Data Converter raw software. This is reflected in our resolution charts, where processed JPEGs outresolve the raw equivalent at ISO 100. Certainly, in low light it is best to shoot in raw, and once the camera's raw files are compatible with software such as Adobe Lightroom, I would expect to get more detail from the files.
There are key points where the noise levels increase noticeably with a subsequent drop the level of resolved detail. At ISO 800 there is a significant drop in resolution as detail begins to become mushy, as it does at ISO 3200. I would avoid this final native setting, along with the two new extended settings that takes the ISO ‘sensitivity' up to 12,800, because detail is poor and the tones are flat. The EX2F is a camera that performs particularly well in good light.
