Canon PowerShot G5 X Review
Canon PowerShot G5 X Image Quality
All of the sample images in this review were taken using the 20 megapixel SuperFine JPEG setting, which gives an average image size of around 8Mb.
The Canon PowerShot G5 X produces images of very good quality. It recorded noise-free images at ISO 125-800, with some noise at ISO 1600. ISO 3200 and 6400 show more obvious noise but still remain perfectly usable, although the fastest setting of ISO 12800 is best avoided.
The Canon PowerShot G5 X handled chromatic aberrations well, with some purple fringing effects appearing only in high contrast situations and generally at the edges of the frame. The built-in flash worked well indoors, with no red-eye and good overall exposure, although there's noticeable vignetting at 24mm. The night photograph was excellent, with the maximum shutter speed of 30 seconds and the Bulb mode being long enough for after-dark shots.
Anti-shake works very well when hand-holding the camera in low-light conditions or when using the telephoto end of the zoom range. Macro performance is good, allowing you to focus as close as 5cm away from the subject. The images were a little soft straight out of the Canon PowerShot G5 X at the default sharpening setting and ideally require some further sharpening in an application like Adobe Photoshop, or you can change the in-camera setting.
The extensive range of My Color modes and Creative Filters make it easy to spice up your images, while the Dynamic Range and Shadow Correction modes help to extract more detail from the shadow and highlight areas.
